Executive Summary This Baseline Phase report outlines the initial findings of the Subtidal Benthos Monitoring Program undertaken between May 2012 and July 2012 as per the methodology outlined in the Ichthys Project Nearshore Environmental Monitoring Plan (NEMP) (Cardno 2012a). As part of the NEMP, sampling was undertaken to characterise the baseline (pre-dredging) conditions of the infaunal assemblages and physical parameters associated with the subtidal soft sediment habitats in Darwin Harbour Inner and Darwin Offshore.

The key objectives of the informative Subtidal Benthos Monitoring Program are to:

> Investigate the potential effects of dredging and dredge spoil disposal on the abundance and diversity of soft-bottom infauna and epifaunal communities;

> Determine whether there are significant changes in sediment characteristics (sediment particle size distrubution (PSD), oxidation-reduction potential (ORP) and pH) before dredging/spoil disposal compared to during and after and how this affects abundance and diversity of soft bottom communities; and

> Follow the subsequent recovery of any infauna and epifauna that may be impacted and relate this to depth of sedimentation, nature of sediment and ORP.

Specific objectives of the Baseline Phase are to:

> Assess the abundance and diversity of infauna and epifaunal assemblages;

> Sample seabed sediment to determine PSD in the predicted Impact and Control locations;

> Assess the ORPand pH of the sediments; and

> Investigate the relationship between the physico-chemical characteristics of the sediment (ORP and pH) and the composition of infaunal and epibenthic assemblages.

The Baseline Phase included an inshore (Darwin Harbour Inner) and offshore (Darwin Offshore) component and was carried out in four consecutive field trips between May 2012 and July 2012, during the Darwin dry season (May to October) and prior to any dredging and spoil disposal activities. Epifauna (animals living mainly on the surface of the seabed), were sampled remotely using a high-definition underwater video drop camera and frame. Sediment samples were also collected with a Ponar grab for abundance and diversity counts of benthic infauna (animals living within the sediment), PSD, pH and ORP.

The overall percentage cover of epifauna was sparse, with ascidians, sponges, hydroids, anemones, bryozoans, macroalgae and filamentous algae collectively accounting for less than 1% of the total mean cover in both the Darwin Harbour Inner and Darwin Offshore surveys. These results suggest that areas likely to be directly affected by dredging activities within the harbour and offshore spoil disposal do not provide any unique or significant habitat for subtidal soft sediment epifauna.

The Darwin Harbour Inner and Darwin Offshore infaunal assemblages sampled were diverse, including several types of crustaceans (amphipods, isopods, tanaids, cumaceans, penaeids, copepods, ostracods, shrimp, hermit crabs, ghost shrimp and brachyuran crabs), polychaete worms (from a variety of families), molluscs (gastropods, bivalves and opisthobranchs), echinoderms (ophiuroids, echinoids, holothurians and seastars) and other worm taxa such as nematodes, nemerteans, oligochaetes, phoronids, platyhelminthes and sipunculids. Other taxa recorded but identified to broader groups included anemones, bryozoans, hydrozoans, sponges, and pycnogonids (sea spiders). A total of 15,487 individual animals comprised of 155 taxa were recorded from the Darwin Harbour Inner survey and 10,295 individual animals comprised of 150 taxa recorded from the Darwin Offshore survey. Darwin Harbour Inner infaunal assemblages did not vary significantly among Control and Impact locations but did vary among sites. Darwin Offshore assemblages varied between Control and Impact locations and among sites within locations.

Darwin Harbour Inner sediments generally had higher proportions of clay and silt with varying proportions of sand and gravel. Darwin Offshore sediments consisted predominantly of sand and gravel with the exception of Control location 2, which contained high percentages of clay and silt. Sediment pH was relatively consistent, varying between 7.3 to 8.0 for Darwin Harbour Inner sites and 6.9 to 8.1 for Darwin Offshore

sites. Mean ORP ranged between -200 mV to 322 mV, for Darwin Harbour Inner sites and -108 mV to 185 mV for Darwin Offshore sites, with strongly reducing conditions typically associated with clay and silty sediment types.

No clear relationships between any physical parameters investigated and the infaunal assemblages observed were evident, suggesting that other hydrographic, physico-chemical or biotic factors drive site and location level distribution patterns.

1 Introduction

1.1 Overview

INPEX is the operator of the Ichthys Gas Field Development Project (the Project). The Project comprises the development of offshore production facilities at the Ichthys Field in the Browse Basin, some 820 km west-south-west of Darwin, an 889 km long subsea gas export pipeline (GEP) and an onshore processing facility and product loading jetty at Blaydin Point on Middle Arm Peninsula in Darwin Harbour. To support the nearshore infrastructure at Blaydin Point, dredging works will be carried out to extend safe shipping access from near East Arm Wharf to the new product loading facilities at Blaydin Point which will be supported by piles driven into the sediment. A trench will also be dredged to seat and protect the GEP for the Darwin Harbour portion of its total length. Dredged material will be disposed at the spoil ground located approximately 12 km north-west of Lee Point. A detailed description of the dredging and spoil disposal methodology is provided in Section 2 of the Dredging and Spoil Disposal Management Plan – East Arm (DSDMP) (INPEX 2012).

1.2 Background

The Baseline Phase monitoring program investigated benthic assemblages of infauna (aquatic animals that live within the soft sediments of the seabed) and epifauna (animals that live on the surface of the seabed), within the subtidal benthic habitats in Darwin Harbour and the nearshore coastal environment. The infaunal component focused on macrofauna which are classified as animals that are retained on a 0.5 mm mesh sieve. This group comprises the vast majority of biomass found in benthic soft sediments (Schwinghamer 1981). In tropical macrotidal estuaries such as Darwin Harbour, infaunal assemblages generally contain burrowing organisms such as polychaete worms, amphipod crustaceans, bivalve and gastropod molluscs and other worm-like phyla such as nemerteans and nematodes (which are often abundant). These animals are generally found within the upper 30 cm of the sediment. As well as being a source of food for organisms higher up the food chain, such as fish and large invertebrates, they also drive nutrient cycling through reworking of the sediments (bioturbation), altering physical and chemical processes, excreting nutrient-rich wastes and feeding on phytoplankton (Pennifold and Davis 2001). The activity of benthic assemblages in nearshore sediments is linked to pelagic processes and thus affects exchange processes between coastal and offshore systems (Eyre and Ferguson 2005; Connell and Gillanders 2007).

The composition of infaunal assemblages is expected to vary both annually and seasonally in relation to the intensity of the wet season and recruitment success (Metcalfe and Glasby 2008). Fluctuations may also occur at shorter time scales (e.g. days to weeks) due to diurnal activity patterns or migrations (Wildsmith et al. 2005). Infaunal assemblages also vary depending on sediment type (Brown and McLachlan 2006). Changes to sediment particle size distribution (PSD) or physico-chemical properties of the sediments are therefore likely to affect the composition of assemblages that are found there. Physical parameters measured as part of the Monitoring Program included sediment PSD, pH and Oxidation Reduction Potential (ORP), which are useful indicators of change, potentially related to dredging/spoil disposal activity.

Epifauna can generally be classed as either sessile (i.e. attached to the seabed) or mobile. Sessile organisms are often attached to hard structure such as reef or gravel, although some sponges, hydroids, ascidians, burrowing anemones and tube building polychaetes can also establish within soft sediments, although epifaunal biota found in association with soft sediments is comparatively sparse compared to that of hard bottom or coral reef substrata. Mobile epifauna associated with subtidal soft sediments often include echinoderms (e.g. seastars, echinoids and holothurians), gastropod molluscs, nemerteans and sipunculid worms among others.

Infaunal and epifaunal assemblages within Darwin Harbour Inner and the spoil disposal area have potential to be affected by dredging activities via three main mechanisms:

> Direct removal from within the dredge footprint;

> Direct smothering via placement of dredged material within the offshore spoil disposal area; and



> Indirect changes to their habitat from the physical changes of the sediment (e.g. through re-suspension and deposition of finer sediment particles released during dredging and spoil disposal activities).

Dredging will remove most of the associated infaunal and epifaunal invertebrates occurring within the dredge footprint. Impacts on subtidal benthic assemblages are likely to be localised and relatively short-term, persisting until re-colonisation occurs. Dispersion of the sediment plume may also have affects beyond the vicinity of the dredge footprint by clogging of respiratory and feeding appendages.

Recolonisation of dredged areas by benthos is likely to occur relatively quickly, occurring within a few months of the cessation of dredging, due to the colonisation of opportunistic species (Sarda et al. 2000; van Dalfsen et al. 2000; Newell et al. 2004). Recovery of benthic assemblages to comparable pre-dredging conditions may, however, take much longer. The rate of recovery of infaunal assemblages will depend on local hydrodynamic conditions, the degree of changes in sediment composition caused by dredging (van Dalfsen et al. 2000) and the successful recruitment of larvae and immigration of mobile species. Recovery may result in assemblages that are quite different in structure from that originally present due to changes in sediment composition and changed water depth. As the material to be mobilised by dredging is not contaminated or vastly different in composition from that at the spoil disposal area, it is unlikely to prevent subsequent recolonisation of disturbed areas (URS 2009).

1.3 Aims and Objectives

The aim of the Baseline Phase is to collect baseline data within Darwin Harbour and offshore spoil ground on the soft-bottom benthos around the predicted Impact and Control locations prior to the start of any dredging and spoil disposal activities.

The objectives of the Subtidal Benthos Monitoring Program are to:

> Investigate the potential effects of dredging and dredge spoil disposal on the abundance and diversity of soft-bottom infauna and epifaunal communities;

> Determine whether there are significant changes in sediment characteristics (sediment grain size, ORP and pH) before dredging/spoil disposal compared to during and after and how this affects abundance and diversity of soft bottom communities; and

> Follow the subsequent recovery of any infauna and epifauna that may be impacted and relate this to depth of sedimentation, nature of sediment and ORP.

Specific objectives of the Baseline Phase are to:

> Assess the abundance and diversity of infauna and epifaunal assemblages;

> Sample seabed sediment to determine PSD in the predicted Impact and Control locations;

> Assess the ORP and pH of the sediments; and

> Investigate the relationship between the physico-chemical characteristics of the sediment (ORP and pH) and the composition of infaunal and epibenthic assemblages.

This report outlines the findings of the Subtidal Benthos Monitoring Program undertaken during the baseline (pre-dredging phase) as per the methodology outlined in the NEMP (Cardno 2012a). The report includes results and analyses of sampling that has been carried out to date, an outline of the methods and Quality Control (QC) procedures that were adopted and a discussion of the outcomes of the Baseline Phase. The Baseline Phase monitoring was carried out during the Darwin dry season in four consecutive trips over neap tide cycles between 30 May 2012 and 17 July 2012.



2 Methodology

2.1 Sampling Locations

2.1.1 Darwin Harbour Inner

Sampling locations within Darwin Harbour (hereafter referred to as Darwin Harbour Inner sampling locations) were selected on the basis of the dredging areas and predicted areas for sediment deposition and turbidity plumes indicated within Section 6.5 of the DSDMP. The sampling design included four locations (ZoMI, ZoI, Control 1 and Control 2), with six sites randomly selected within each location, yielding a total of 24 sites (Figure 2-1). Habitat maps provided in the DSDMP were used to identify sites with similar sediment characteristics.

2.1.2 Darwin Offshore

Darwin Offshore sampling locations were selected to investigate the impacts of the spoil disposal area located approximately 12 km northwest of Lee Point (Figure 2-2). Previous surveys have described the spoil disposal area as a flat seabed with depths ranging from 15 m in the south-west end to 20 m in the northeast end, comprised of a relatively featureless seafloor with sand/silt and very sparse epibenthic fauna (URS 2009).

In additional to the spoil disposal area, two sampling locations were included to the east of the spoil disposal area: Zone of Impact (Near) and Zone of Impact (Far). Based on model predictions, these are located in the zone of sediment suspension and deposition from the dredge spoil disposal area.

Two Control locations (Control 1 and Control 2) were situated approximately 20 km west of the spoil ground and away from the proposed pipeline location, north-west of Charles Point, following a similar 10 m to 14 m depth contour as the Impact locations (Figure 2-2). These locations were chosen as they were expected to have similar depth and bottom type to that previously observed at the spoil disposal area. Six sites within each location were selected at random within each location.

Locations for the Darwin Offshore survey were similar in size as the dredge spoil disposal area (i.e. 5 km x 2.5 km). Sites within locations were also standardised to an area of ~200 m x 200 m.

2.2 Sampling Design

The proposed sampling design is consistent with the ‘beyond BACI’ (Before, After, Control, Impact) sampling approach, which makes use of multiple controls in space and time (Underwood 1991, 1992; Long et al. 1996). This allows changes at a potential impact location to be evaluated against variation measured at multiple control locations. The design requires that sampling be carried out in at least two external control locations in addition to the potential impact locations. Monitoring was undertaken at Darwin Harbour Inner and Darwin Offshore sampling locations in relation to the dredge area and spoil disposal areas. As the Baseline Phase survey was carried out during the Darwin dry season (May to October), further surveys during and after dredging will be carried out at the same time of year to allow comparison.

The monitoring program would be conducted in four phases:

> Phase 1: Baseline sampling;

> Phase 2: During dredging (the most intensive phase);

> Phase 3: Post dredging (at the end of dredging); and

> Phase 4: Post dredging (one year post-dredging).

The sampling design for each area is outlined below (Table 2-1).

2.3 Field Methodology

2.3.1 Epibenthic Habitats

Epifauna was photographed using a high-definition underwater video drop camera and frame (Figure 2-3). The drop camera yields high quality photographs in low light and low visibility conditions and produces images suitable for photoquadrat analysis. The drop camera consisted of a Sony HDR- CX700 (1080i) digital video camera, fitted with a 0.6 wide angle conversion lens video camera, pointing downwards, mounted within a watertight housing and frame and deployed from the survey vessel. The camera automatically adjusts focus and exposure to suit conditions on the seafloor. The frame was built from solid aluminium and consisted of four padded legs and a cradle to hold and secure the housed video camera. The unit was deployed with 1.35 kg of lead weight attached to each leg as ballast to provide stability in surge or current. A length of silver rope was attached to each corner of the frame for deployment and retrieval of the unit. The camera was lowered to the seabed at the start of each transect and raised and lowered to approximately 50 cm above the substratum as the vessel drifted with the current (between 0.5 and 1 km/hr) until the end of the transect. The camera sat approximately 50 cm above the seabed providing a quadrat size of ~ 40 cm x 65 cm. Fifteen replicate quadrats were taken per transect. Darwin Harbour Inner transects were approximately 50 m in length and Darwin Offshore transects approximately 100 m in length. Upon completion of each transect (A and B) at a site, the video camera was retrieved and video footage was downloaded onto a laptop computer and external hard drive as a back-up.

GPS positions of each site were recorded so the exact same positions could be revisited in future surveys. Vessel movements throughout the course of the day were also tracked and downloaded.

2.3.2 Benthic Infauna

Sediment samples to be analysed for benthic infauna, PSD, pH and ORP were collected using a stainless steel Ponar benthic grab deployed by winch to the seabed at each site. The Ponar grab can collect up to 4.5 L of sediment, with a bite depth of 90 mm and was fitted with stainless steel mesh flaps to retain surface biota greater than 0.5 mm in size. Sample volume, water depth, time and GPS position of each grab sample were recorded. Infauna samples were sieved on board the vessel through a 0.5 mm mesh sieve, with retained sediment and biota transferred to a labelled bag. The sieve was examined after removal of retained sediment and any animals trapped in the mesh added to the sample, rinsing with water to avoid any cross-contamination. The sample was then preserved on board the vessel in a solution of 40% formalin and seawater with Rose Bengal dye. Formalin stored on board the vessel was bunded within a plastic container to ensure no leakage onto the deck. Sample bags were labelled internally and externally with project details, time, date, location, site and replicate number and placed in a sealed labelled poly-drum.

2.3.3 Particle Size Distribution (PSD)

Sediment samples collected for PSD analysis were sealed into labelled bags and placed in a cooler to be stored below 4°C until transfer to a freezer on land. They were later dispatched to a National Association of Testing Authorities (NATA) accredited laboratory (ALS Laboratories Darwin), accompanied by a Chain of Custody (COC) document for external laboratory analyses.

2.3.4 pH

Immediately after sample collection and prior to sieving, pH measurements were recorded using an Oakton Instruments waterproof pH tester pen (Figure 2-3). The probe was inserted 4 to 5 cm into the sediment sample and left until the value on the instrument remained stable. Values were recorded on the field data sheet. Tester pens were calibrated prior to each field trip and rinsed in a bucket of fresh water between measurements.

2.3.5 Oxidation Reduction Potential

Immediately after sample collection and prior to sieving, ORP measurements were recorded using an Oakton Instruments waterproof ORP tester pen (Figure 2-3). The probe was inserted 4 to 5 cm into the sediment sample and left until the value on the instrument remained stable or after 30 seconds (whichever was sooner). Measurements were then recorded on the field data sheet. Tester pens were calibrated prior to each field trip and rinsed in a bucket of fresh water between measurements.

2.4 Laboratory Methodology


Still images of each camera drop were captured using VLC Media Player. Each captured still was colour corrected using Adobe Photoshop to allow for better quality images and aid in the processing of photoquadrats. Each video transect was reviewed and a general habitat description recorded. Photoquadrats were processed using the Coral Point Count with Excel extensions (CPCe) program (Kohler and Gill 2006). The analysis involved digitally overlaying a virtual photoquadrat (scaled to approximately 40 cm x 65 cm) with 64 points in a random stratified grid on each captured video frame (Figure 2-4). Each point was then assigned a category as indicated in Table 2-2. This provided an estimate of the percentage cover of each habitat category (including biotic and abiotic categories).

2.4.2 Benthic Infauna

Samples for analyses of infaunal assemblages were sent via road freight to Cardno’s in-house laboratory. Excess formalin in samples was initially drained from each sample over a 0.5 mm mesh sieve and appropriately disposed of. Samples were then rinsed under tap water and transferred to an alcohol solution for preservation and further processing. Large sandy samples (greater than 0.5 L) were elutriated to separate animals from the substrate and improve sorting efficiency. The coarse fraction settled out from the elutriation was then sorted in a tray to remove any larger invertebrates (such as bivalves) which may have not been extracted during the elutriation. Animals were then removed from the sediment and elutriate fractions under a binocular microscope using forceps and stored according to their taxonomic group with the Project details and sample information. Animals were identified to Family level with each taxon separated into an individually labelled vial. For groups where further identification would require a large expenditure of time (e.g. oligochaetes and nematodes) or where taxonomic status in Australia was insufficient to achieve a finer level of identification (e.g. anemones), identification was to a lower resolution such as Class or Sub Order.

2.4.3 Particle Size Distribution (PSD)

Samples collected for analysis of PSD were dispatched to ALS Laboratories, Darwin, a NATA accredited laboratory, accompanied with COC documentation. The distribution of particles sizes greater than 0.001 mm and median grain size were determined using the dry sieve (AS 1289.3.6.1) and hydrometer (AS1289.3.6.3) methods.

2.5 Statistical and Analytical Methodology

2.5.1 General Findings

General findings for infaunal assemblages are presented as total numbers of individuals and total number of taxa (taxon richness) occurring among sampling sites. General findings for physical parameters (PSD, pH and ORP) are presented as averages and standard errors (SE) of the mean for all sampling sites.

2.5.2 Multivariate Analyses

Statistical analysis of infauna data was done using PERMANOVA+ (based on Bray-Curtis dissimilarity matrices) in PRIMER v6. This is a permutational approach to analysis of variance (ANOVA) that is superior to traditional methods (Anderson et al. 2008) in that there is no assumption of normality in the data and designs can be unbalanced (e.g. different numbers of replicate samples at different places or times) if necessary. The approach yields exact tests for each level of an experimental design and is robust to differences among variances. Post–hoc permutational t-tests or ‘pair-wise’ tests using PERMANOVA+ were performed to examine significant interactions of main effects. Prior to analyses, any samples with greater than 50% poor quality/shadow or indeterminate categories were removed.

As transformation of data to achieve normality was unnecessary, abundance data were not transformed. In order to help discriminate between groups of interest (in this case locations/treatments and sites), multivariate data were represented graphically using Principle Coordinates Analysis (PCoA), a generalised form of Principal Components Analysis (PCA), which complements the permutational ANOVA procedure (Anderson et al. 2008). Samples were projected onto linear axes based on their dissimilarities in a way that best describes the patterns among them using as few dimensions as possible (Clarke and Gorley 2006).

Similarity Percentage Analysis (SIMPER) was used to identify those taxa, or groups of taxa contributing most to dissimilarities between assemblages where appropriate.

Differences in the dispersion of data between surveys were examined using the PERMDISP routine in PERMANOVA+. This routine was used to separate the effects of differences in dispersion of points within clusters from differences in the relative positions of the clusters (Anderson et al. 2008).

The design for the statistical analyses for each component of the baseline survey was as follows:

1. Darwin Harbour Inner Drop Camera

> Location: 4 levels (ZoMI, ZoI, Control 1, Control 2), fixed;

> Sites: 24 levels, random, nested in treatment;



> Transects: 2 levels (A and B), random, nested in site; and

> Replicates: x 15.

2. Darwin Harbour Inner Grab Sampling

The design for the statistical analyses (Darwin Offshore) was:

> Location: 4 levels (ZoMI, ZoI, Control 1, Control 2), fixed;

> Sites: 24 levels, random, nested in treatment; and

> Replicates: x 5.

3. Darwin Offshore Drop Camera

> Location: 5 levels (spoil disposal area, Zone of Impact (Near), Zone of Impact (Far), Control 1, Control 2), fixed;

> Sites: 6 levels (sites 1 -6), random, nested in treatment;

> Transects: 2 levels (A and B), random, nested in site; and

> Replicates: x 15.

4. Darwin Offshore Grab Sampling

> Location: 5 levels (spoil disposal area, Zone of Impact (Near), Zone of Impact (Far), Control 1, Control 2), fixed;

> Sites: 6 levels (sites 1 - 6), random, nested in treatment; and

> Replicates: x 5.

2.5.3 Univariate Analyses

Where appropriate, univariate analyses were done to investigate differences in taxon richness, taxon abundance and individual taxa contributing the most to the spatial and temporal variability among samples. PERMANOVA+ (based on Euclidian distance) was used to perform permutational analyses of variance as this approach does not require that the data come from a normal distribution or that variances are homogeneous, as is the case with traditional ANOVA. After calculating a Euclidean distance matrix of all possible pairs of samples of the variable of interest, the underlying distribution of the data was determined by repeated randomisation of the samples in the matrix, enabling exact tests for all levels of the experimental design (Anderson et al. 2008).

2.5.4 Relating Physical and Biological Variables

To examine the relationship between the physical variables of PSD, pH and ORP with the biotic data, a sub-program within the PRIMER package called Distance Based Linear Models (DIST-LM) was used. DIST-LM models the relationship between a multivariate data cloud (as described by a resemblance matrix) and one or more predictor variables that were measured from the same set of samples. P-values for testing the null hypothesis of no relationship are obtained using permutation methods rather than traditional tables.

2.6 Quality Control Procedures

2.6.1 Field

As per the requirements of INPEX’s Waste Discharge Licence (WDL) and EPA 8 permit conditions on reporting, for all replicate samples collected, a unique sample code, a record of the GPS position, time, date, depth, name of the sampler, sediment type and weather conditions were recorded on waterproof field sheets. All data were then transcribed into the master project database linked to each unique sample code. GPS positions were downloaded into excel format then imported into the master database. A photographic record was also archived for each PSD grab sample collected. Sediment samples were transferred into polyurethane bags and labelled internally and on the outside of the bag. Hard copies of all original datasheets were scanned and stored electronically within the master database.



COC documentation accompanied all consignments of samples being transported from one party to another. Field quality assurance included the collection and analysis of a duplicate sample at a randomly selected site. External laboratory quality assurance included the use of blind replicate environmental samples.

2.6.2 Laboratory

All samples were logged upon receipt from the field on a laboratory management sheet. In the laboratory, a sample sign-in/sign out system was used to track sample status and time required to process each sample. For each sample, the sediment remaining after removal of all biota was checked by a second experienced person to recover any missed organisms. Verification of identifications and counts were completed by a second experienced scientist on all samples. A voucher collection was retained for future comparison and identification. External laboratory quality assurance included the use of blind replicate environmental samples.

2.6.3 Data Processing

Personnel involved in sampling photographs using CPCe were required to demonstrate proficiency before being authorised to begin sampling of photoquadrats. Proficiency was acquired through training by an experienced scorer available to assist CPCe analysts full time throughout processing. All photos were checked by a senior staff member for consistency and accuracy. Once these checks were completed, the Scope Leader or Data Manager approved the images for release within Vault for exporting to the SQL database. Before exporting data to Excel, the CPCe files were examined to ensure that all the points of each quadrat (i.e. 64 points) were scored and check that there was a CPCe file (‘.cpc’) for every photograph allocated. If a file was missing, it was analysed prior to the CPCe data being exported to the SQL database.

Prior to use in statistical analyses, data files were locked to avoid corruption or accidental over-write. The video analysis and all field data was error checked before undertaking further analysis or presentation using a two-scientist, digital and hard copy procedure. This involved one person entering the data and two scientists then checking the digital and hardcopies against each other.

3.1 Darwin Harbour Inner


3.1.1.1 General findings

General habitat descriptions for each site are provided in Appendix B. Video stills representative of the epibenthic environment have also been provided to assist in the interpretation of habitat descriptions. In general, seabed consisted of relatively flat bare, bioturbated fine sand with silty clay and coarser sand/shell grit. Epifauna was minimal, limited to the rare occurrence of bryozoans, hydroids and sea whips. CPCe summary data for each transect (A and B) within sites 1-24 are presented in Appendix C. Overall, sand (including fine sand and silt) was the most abundant category across the Darwin Harbour Inner survey, accounting for approximately 70% of mean coverage. Shell grit accounted for 9.6% of cover followed by algal mat on sand (5.4%), bioturbated sand (2.5%) and burrows (1.3%). The overall percentage cover of epifauna was very sparse, with ascidians, sponges, hydroids, anemones, bryozoans, macroalgae and filamentous algae collectively accounting for less than 1% of the total cover sampled. The remaining coverage (approximately 10%) was either indeterminate, obscured by shadow or visibility was too poor to accurately assign a data point. The greatest percentage cover of epifauna was recorded at sites 2, 11, 18, 16 and 19. The percentage contribution of each category for each site is presented graphically in Appendix

D.



3.1.1.2 Analyses of Assemblages

Epifaunal assemblages varied at the scale of locations (several kilometres), sites (hundreds of metres) and transects (metres) within Darwin Harbour. Percentage cover of epibenthic categories sampled from the ZoMI, ZoI, Control 1 and Control 2 varied significantly (Appendix E), with pairwise tests indicating that this was due to Control location 1 being significantly different in composition from all other locations (Appendix

F). This is illustrated in the PCoA plot (Figure 3-1), which shows that 84% of the total variation can be explained by differences among samples. SIMPER analyses indicated that differences between Control location 1 and other locations were due to a smaller percentage cover of sand and greater percentage cover of shell grit (Appendix G) at Control location 1. Samples from Control location 1 were also more variable than at other locations as indicated from the results of the pairwise PERMDISP analyses (Appendix H). When biotic categories were analysed separately from the abiotic categories, the epibenthic assemblages were found to differ at the level of sites but not among locations (Appendix E).

3.1.2 Infauna

3.1.2.1 General Findings

A total of 15,487 individual animals comprised of 155 taxa were recorded from the Darwin Harbour Inner subtidal benthos survey. A diverse range of taxa were collected, including numerous types of crustaceans (amphipods, isopods, tanaids, cumaceans, penaeids, copepods, ostracods, shrimp, hermit crabs, ghost shrimp and brachyuran crabs), polychaete worms (from a variety of families and feeding guilds), molluscs (gastropods, bivalves and opisthobranchs), echinoderms (ophiuroids, echinoids, holothurians and seastars) and other worm taxa such as nematodes, nemerteans, oligochaetes, phoronids, platyhelminthes and sipunculids. Other taxa recorded but identified to broader groups included anemones, bryozoans, hydrozoans, sponges, pycnogonids (sea spiders) and juvenile fish. Raw sample data are presented in Appendix I.

Crustaceans were the most numerically abundant of the major taxonomic groups, followed by polychaetes, other worm phyla (e.g. nemerteans, nematodes, phoronids and sipunculids), molluscs, other phyla and echinoderms. Crustaceans were also the most diverse in terms of taxon richness followed by polychaete worms, molluscs, other phyla, other worm phyla and echinoderms (Table 3-2, Figure 3-2).

The most numerically abundant taxa throughout the Darwin Harbour Inner survey were tanaid crustaceans from the family Apseudidae (contributing to 17.3% of the total abundance), followed by amphipod crustaceans from the family group Aoridae/Isaeidae and Photidae (12%), polychaete worms from the families Spionidae (5.8%), Ampharetidae (5.4%) and Capitellidae (2.9%), nematodes (2.8%), nemerteans (2.8%), and polychaetes from the families Maldanidae (2.7%), Cirratulidae (2.0%) and Syllidae (1.9 %) (Figure 3-3). Representative taxa from other phyla and family groups are presented in Figure 3-4.

Mean abundance and taxon richness did not vary significantly among locations (ZoMI, ZoI, Control 1 and Control 2) but did vary among sites within locations. Abundance was greatest at site 6 (within East Arm) and lowest at sites 8 (main channel), 18 (main channel) and 24 (West Arm). Taxon richness was greatest at sites 1, 13 and 15 (all within the main channel) and lowest at site 3 (within the proposed dredge footprint), site 8 (main channel) and Site 24 (West Arm) (Figure 3-5).

Infaunal assemblages did not vary significantly among locations, but did vary among sites within locations (Appendix E) as shown by pairwise tests (Appendix F). This is illustrated in the PCoA plot (Figure 3-6), although this shows that only 25% of the total variation can be explained by differences among samples represented by the two axes. Various taxa including polychaetes, tanaids, amphipods, bivalves and anemones were responsible for significant variation among sites as indicated in the results of the SIMPER analyses.

3.1.3 Particle Size Distribution

Sediment samples collected from Darwin Harbour contained sand with varying proportions of clay, silt and gravel. Sites located to the far west of Darwin Harbour Inner had a high clay and silt content, whereas samples collected from the central channel tended to contain higher proportions of gravel than elsewhere. Samples collected from within the East Arm were mostly sandy with smaller proportions of clay and silt (Figure 3-7). Mean particle size data are summarised in (Table 3-3). Raw PSD data for Darwin Harbour Inner sampling sites are presented in Appendix J.

3.1.5 Relationship of Physical and Biological Variables

Examination of the distance based linear model indicated that very little of the variation of the Darwin Harbour Inner infaunal assemblage could be attributed to the physical variables measured (median grain size, pH and ORP). Cumulatively these variables explained less than 10% of the total variation (R2 for each individual variable against the infaunal data cloud = <0.04). This is illustrated in the distance based redundancy analyses ordination (dbRDA) (Figure 3-10). Statistical results are presented in Appendix K.

3.2 Darwin Offshore


3.2.1.1 General findings

General habitat descriptions are provided in Appendix B. Video stills representative of the epibenthic environment have also been provided to assist in the interpretation of habitat descriptions. In general, seabed consisted of relatively flat, bare, bioturbated fine sand with silty clay and coarser sand/shell grit. Epifauna was limited to the occasional occurrence of sponges, bryozoans, hydroids, macroalgae and sea whips. Hard coral fragments were also present, but rare within the spoil disposal area and at Control location 1.

CPCe summary data for each transect (A and B) within the Darwin Offshore monitoring locations is presented in Appendix C. Overall, sand (including fine sand and silt) was the most abundant category across the Darwin Offshore survey accounting for approximately 71% of mean coverage. Shell grit accounted for 4% of cover followed by bioturbated sand (2%), algal mat (1.1%) and rubble (0.6%). The overall percentage cover of epifauna was very sparse, with ascidians, sponges, hydroids, anemones, bryozoans, macroalgae and filamentous algae collectively accounting for less than 1% of the total mean cover. The remaining coverage (approximately 20%) was either indeterminate, obscured by shadow or visibility was too poor to accurately assign a data point. The greatest percentage cover of epifauna was recorded at the Zone of Impact (Far) (sites 3 and 1), followed by Control location 1 (sites 3 and 4). The percentage contribution of each category for each location and site is presented graphically in Appendix D.


In Darwin Offshore, epifaunal assemblages varied at the scale of locations (several kilometres), sites (hundreds of metres) and transects (metres). Percentage cover of epibenthic categories sampled from the Spoil Disposal Area, Zone of Impact (Near), Zone of Impact (Far), Control location 1 and Control location 2 varied significantly (Appendix E). Pairwise tests indicated that this was due to significant differences between the Spoil Disposal Area and Zone of Impact (Far)/Control location 1, and differences between Control locations 1 and 2 and the Zone of Impact (Near) and Zone of Impact (Far) (Appendix F). This is illustrated in the PCoA plot (Figure 3-11) which shows that 64% of the total variation can be explained by differences among samples. SIMPER analyses indicated that differences among locations were mainly due to varying percentages of sand, shell grit, bioturbated sand, rubble and to a much lesser extent, sponge (Appendix G). Samples from within the Spoil Disposal Area and Zone of Impact (Near) were generally less variable than at other locations as indicated from the results of the pair-wise PERMDISP analyses (Appendix H).

3.2.2 Infauna

3.2.2.1 General Findings

A total of 10,295 individual animals comprised of 150 taxa were recorded from the Darwin Offshore subtidal survey. A diverse range of taxa similar to that recorded for the Darwin Harbour Inner survey were collected, including numerous types of crustaceans (amphipods, isopods, tanaids, cumaceans, penaeids, squat lobsters, copepods, ostracods, shrimp, hermit crabs and brachyuran crabs), polychaete worms (from a variety of families and feeding guilds), molluscs (bivalves, opisthobranchs, nudibranchs and microgastropods), echinoderms (ophiuroids, echinoids, holothurians and crinoids) and other worm like taxa such as nematodes, nemerteans, oligochaetes, phoronids, platyhelminthes and sipunculids. Other taxa recorded but identified to broader groups included anemones, bryozoans, hydrozoans, sponges, pycnogonids (sea spiders), branchiostomes (small eel-like invertebrates) and juvenile fish. Raw sample data are presented in Appendix I.

Polychaete worms and crustaceans accounted for the greatest abundance and taxon diversity throughout the Darwin Offshore Baseline Phase survey, with polychaetes being the most numerically abundant of the major taxonomic groups. Crustacea was the next most numerically abundant group, followed by Mollusca, other worm phyla (e.g. nemerteans, nematodes, phoronids and sipunculids), Echinodermata and other phyla (e.g. anemones, hydroids, sponges and sea spiders). Crustaceans were the most diverse of the major taxonomic groups, followed by polychaetes, molluscs, other phyla, other worm phyla and echinoderms (Table 3-5, Figure 3-12).

The most numerically abundant taxa throughout the Darwin Offshore survey were amphipod crustaceans from the family group Aoridae/Isaeidae/Photidae (contributing 15.7% of the total abundance), followed by tanaid crustaceans from the family Apseudidae (7.2%), polychaete worms from the families Spionidae (4.9%), Capitellidae (4.7%), Maldanidae (4.2%), Ampharetidae (3.9%) and Nephtyidae (3.2%), amphipod crustaceans from the family Ampeliscidae (3.2%), tanaid crustaceans from the family Leptochelidae (2.9%) and nemerteans (2.4%). Examples of the most numerically abundant taxa (from the Darwin Harbour Inner survey) are shown in Figure 3-3. Representative phyla collected during the Darwin Offshore survey are also presented in Figure 3-13.

Mean abundance did not vary significantly among locations (Spoil Disposal Area, Zone of Impact (Near), Zone of Impact (Far), Control 1 and Control 2) but did vary among sites within locations. Abundance was greatest at Control location 2 (site 3) and Control location 1 (site 1), although the fewest numbers of individuals were also found in samples collected from both Control locations. Taxon richness was significantly different among locations due to differences between Control location 2 and the Spoil Disposal Area/Zone of Impact (Near). The greatest diversity of taxa was found at Control location 1 (site 1) and the Spoil Disposal Area (site 5) (Figure 3-14).

Infaunal assemblages varied significantly among locations and sites within locations (Appendix E). Pairwise tests (Appendix F) showed that these location-scale differences were explained by differences between the two Control locations and the three Impact sites, but also between the Zone of Impact (Far) and the Zone of Impact (Near)/Spoil Disposal Area. Locational differences were also due to variation in the dispersion of samples (i.e. variability among samples within each location) (Appendix H). This is illustrated in the PCoA plot (Figure 3-15), although this shows that only 24% of the total variation can be explained by differences among samples represented by the two axes.

Taxa driving these locational differences were tanaids (Apseudidae and Leptochelidae), amphipods from the families Aoridae/Isaeidae/Photidae and Ampeliscisdae and polychaetes from the families Spionidae, Capitellidae, Maldanidae and Ampharetidae (Figure 3-16, Figure 3-17, Figure 3-18, Appendix G).

3.2.3 Particle Size Distribution

Sediment samples collected from the spoil disposal area contained a large proportion of sand with smaller proportions of gravel, clay and silt. This distribution was fairly uniform across the six sites sampled within the Spoil Disposal Area and the Zones of Impact (Near and Far). The proportion of gravel recorded from Control location 2 was notably smaller than at the other four locations (Figure 3-19). Mean particle size data are summarised in Table 3-6. Raw PSD data for Darwin Harbour Inner sampling sites are presented in Appendix J.

3.2.5 Relationship of Physical and Biological Variables

Examination of the distance based linear model indicated that very little of the variation of the Darwin Offshore infaunal assemblage could be attributed to the physical variables measured (median grain size, pH and ORP). Cumulatively these variables explained less than 10% of the total variation (R2 for each individual variable against the infaunal data cloud = <0.05). This is illustrated in the distance based redundancy analyses ordination (dbRDA) (Figure 3-22). Statistical results are presented in Appendix K.

4 Discussion

The overall percentage cover of epifauna sampled within Darwin Harbour Inner was sparse, with ascidians, sponges, hydroids, anemones, bryozoans, macroalgae and filamentous algae collectively accounting for less than 1% of the total area sampled. This would be expected given the predominantly sandy substratum and the fact that many sessile invertebrates require a hard surface to form a stable attachment to the seabed. The epifauna observed in the drop camera survey may have been limited to those groups that are able to burrow a holdfast into the sediment or that have settled on an occasional clump of rubble or gravel (such as some species of anemones, sponges and sea whips). Very few examples of mobile epifauna were observed in photoquadrats, although tracks of small gastropod molluscs and the occasional demersal fish were noted. Large burrows were commonly observed suggesting the presence of crabs or other mobile crustaceans. Visibility was particularly poor at some of the Darwin Harbour Inner Control locations at the time of sampling therefore the percentage cover of epifauna observed at these locations is likely to have been conservative. Although a relatively small proportion of epifauna was observed in terms of the area sampled, at the scale of the harbour, this epifauna may provide important structure or refuge in an otherwise sparse subtidal seabed. No significant epifauna was observed within the dredge footprint or ZoMI.

The epifaunal assemblage at the Darwin Offshore sampling locations was similar to that of the Darwin Harbour Inner survey, with less than 1% of epifaunal cover. Results suggest that the Darwin Offshore spoil ground does not provide any unique or significant habitat. This is consistent with the findings of drop camera surveys of the spoil disposal ground carried out as part of the Ichthys Gas Field Development Project Environmental Impact Statement (EIS) (URS 2009).

Darwin Harbour Inner and Darwin Offshore subtidal benthic assemblages were diverse, with 155 and 150 taxa recorded from the Darwin Harbour Inner and Darwin offshore surveys respectively and approximately 169 taxa across the two surveys combined. The number of actual ‘species’ occurring in Darwin Harbour Inner and Darwin Offshore is likely to be significantly more than the number of taxa identified to family level (or higher), as more than one morpho-species were noted for several families during the identification process. Similar taxa were numerically abundant in both the Darwin Harbour Inner and Darwin Offshore surveys, including tanaid and amphipod crustaceans, several polychaete families, nematodes and nemerteans, although several species not recorded in the Darwin Offshore survey were present in the Darwin Harbour Inner survey and vice versa. All of the numerically abundant species recorded in the Darwin Harbour Inner and Darwin Offshore surveys are ubiquitous to most marine habitats and commonly found to occur in large numbers.

In Darwin Harbour Inner, variability was occurring at the site level but not at the broader (locational) scale for the infauna assemblages sampled. This was not the case in the Darwin Offshore infauna survey, where both locational and site level variation was evident. Variation at the locational scale may have been a result of smaller sample sizes at the Darwin Offshore Control locations (due to limited soft sediment habitat) which may have caused the lower abundances and taxon richness evident at these locations.

Multiple biotic and abiotic factors are reported to affect the distributional patterns of shallow water benthic infauna (Currie and Small 2006), with one of the major physical influences being PSD (Brown and McLachlan 2006; Sundberg and Kennedy1993; Butman and Grassle 1992). However, results of the distance based linear model did not indicate any clear relationship between median grain size and the infaunal subtidal assemblage data for the Darwin Harbour Inner or Darwin Offshore surveys. This is not due to inadequacies of the model (which captures around 80% of the fitted variation in both Darwin Harbour Inner and Darwin Offshore data), but suggests that other hydrographic, physico-chemical or biotic factors drive site and location level distribution patterns. Co-variance with parameters may also misrepresent causal mechanisms between organisms and particle size (Aller et al. 2001).

Mean sediment pH and ORP was within the ranges that would be considered normal for similar marine systems. Sites containing a high proportion of clay and silt were generally reducing, whereas those containing a high proportion of sand were generally oxidising. High proportions of clay and silt in samples limits water circulation and hence oxygenation potential, generally resulting in strongly reducing conditions. No relationship between pH, ORP and the infaunal subtidal assemblage data for the Darwin Harbour Inner or Darwin Offshore surveys was observed.



General conclusions may be drawn from comparison of the Subtidal Benthos Baseline Phase Monitoring Survey and the Intertidal Benthos Baseline Phase Monitoring Survey which were carried out concurrently as part of the NEMP during the period from June 2012 to August 2012. That is, taxon richness and abundance was greater for the subtidal habitats (Darwin Harbour Inner and Darwin Offshore) than the intertidal habitats (Cardno 2012b), which is consistent with studies reporting macrofaunal abundance and species richness to be relatively low on beaches, higher in intertidal sand and mud flats and increasing in the shallow subtidal habitats of estuaries and towards the shelf (Metcalfe and Glasby 2008; Connell and Gillanders 2007; Smit 2003). The percentage contribution of major taxonomic groups was also distinctly different between intertidal and subtidal assemblages, with the intertidal assemblages characterised by a high proportion of polychaete families whereas a greater number of crustacean taxa were represented in the subtidal surveys (Cardno 2012b). Direct quantitative comparisons cannot be made due to differences in the sampling effort between the two monitoring programs.

Appendix E. Permutational Analysis of Variance of CPCe percent cover/infaunal assemblages sampled during the baseline sampling phase (May to July 2012). P-values highlighted in bold are significant. RED = Redundant term. A term becomes redundant if a lower order interaction including that term is significant. Res = Residual. This term is a measure of the variation in the data not explained by the variation attributed to the main factors in the experimental model (i.e. location, site, transect). 1. CPCe (inshore)
