Introduction

This cruise report provides a summary of scientific activities aboard the SSV Corwith Cramer

during Cruise C-268A (August 8, 2016 – August 15, 2016). This was an SEA Invitational Sail,

during which invited participants sailed from Cádiz, Spain to Alicante, Spain, with brief

overnight stops in Málaga and Cartagena. While onboard the ship, the participants shared the

experience of sailing and shipboard life and learned about SEA and SEA’s academic programs.

True to SEA and SEA Semester, they became part of the crew and stood watch, handled sail,

navigated, steered, performed boat checks, and helped in the science lab and galley. Scientific

sampling was conducted throughout the cruise in easternmost Atlantic Ocean and western

Mediterranean Sea waters.

Data Description

This section provides a record of data collected aboard SSV Corwith Cramer Cruise C-268A, which departed

from Cádiz, Spain and voyaged through the Straits of Gibraltar and along the Spanish Mediterranean coast for

approximately 475nm before ending in Alicante, Spain (Figure 1).

During the 8-day cruise, we occupied three oceanographic stations. We collected biological

samples with the neuston net at the first station, conducted a vertical meter net tow at a second

station, and deployed styrofoam cups at a third oceanographic station to evaluate the effects of

water pressure on cup shrinkage (Table 1). Additionally, we continuously sampled water depth

and sub-bottom profiles (CHIRP system), oceanographic currents (ADCP), and sea surface

temperature, salinity, and chlorophyll in-vivo fluorescence with the seawater flow-through

system. Wind speed and direction were also recorded. No CTD, hydrocast, or sediment

sampling deployments were made. Data summaries of the neuston tow sample are given in

Tables 2 and 3. Voluminous ADCP, CHIRP, and flow-through data are not fully presented

here. All unpublished data can be made available by arrangement with the SEA data archivist

(contact information, p. 2). The brief summary of C-268A data contained in this report is not

intended to represent final data interpretation and should not be excerpted or cited without

written permission from SEA.

2 Station C268A-002-MN comprised a vertical meter net tow, conducted while the ship was hove to. Mostly clear gelatinous organisms

were recovered, including siphonophores and small salps. Clear copepods, chaetognaths, and fish larvae were also present. The

recovered sample was not quantitatively analyzed, and no 100-count of zooplankton was conducted.

3 Station C268A-003 was a styrocast, during which styrofoam cups were deployed on the hydrowire to a depth of 2000m in order to

test the effects of pressure on cup shrinkage. No additional oceanographic data were collected at this station.

Data Description C269

The cruise track for C-269 (Figure 1) departed from Barcelona, Spain and concluded in Las

Palmas, Gran Canaria 41 days later. During the nearly six-week voyage we had three port stops;

the first in Palma de Mallorca, Spain; the next in Cadiz, Spain and the third was a return to

Cadiz, Spain after a short sail in the Gulf of Cadiz that was thwarted by weather conditions.

Our cruise track traversed several major oceanographic provinces (Figure 1): a) the productive,

warm, salty waters of the NW Mediterranean Sea, b), the less productive, warm, less salty waters

of the SW Mediterranean Sea, c) the very productive, transitional waters of the Alboran Sea, d)

the productive, cool and less salty waters of the Gulf of Cadiz, and e) the less productive, cool,

salty waters of the sub-tropic, eastern North Atlantic.

We collected data with 120 individual deployments from 45 discrete geographic stations along

our cruise track. Comparison of the physical, chemical, biologic and geologic features of these

regions represented the major oceanographic theme of this Sea Semester.

1. Physical oceanographic studies focused on the distribution of surface and sub-surface (to

2000 m) water masses and the delineation of hydrographic boundaries. Specifically,

Modified Atlantic Water, Levantine Intermediate Water, Western Mediterranean Deep

Water, and the Western Mediterranean Transition Water. Outside the Mediterranean

basin we looked for ‘Meddies’ (sub-surface Mediterranean eddies).

2. Chemical oceanographic studies focused on the geographic and vertical distribution of

nutrients (phosphate and nitrate), extracted chlorophyll-a, coliform bacteria, and pH.

These chemical parameters were related to patterns in physical hydrography at various

scales: nearshore to offshore transitions, ocean fronts and eddies associated with island

passages, the Strait of Gibraltar, and water column stratification.

3. Biological studies focused on the geographic distribution of charismatic megafauna

(seabirds, sea turtles, flying fish, and marine mammals), several nektonic organisms

(lantern fish – Family Myctophidae, and gelatinous organisms >2cm – i.e Pelagia

noctiluca), meroplanktonic larvae including spiny lobster (phyllosoma) and eels

(leptocephali), the marine insect Halobates, and the density (mL/m2) and diversity (i.e.

Shannon-Weiner index) of the aggregate zooplankton community including pteropods.

4. Geological sampling focused on surface sediment samples collected from continental

shelf regions near each port stop. Patterns were related to coastal development and

distance from shore.

Sea surface temperature, salinity, fluorescence (chlorophyll-a and CDOM) and transmissivity

levels; along with barometric pressure, winds, bathymetry, and geographic position were

recorded continuously along the cruise track. Large-scale hydrography is summarized with

surface plots for some parameters (Figure 2a-c) other data is available upon request. Surface

samples (85) of nutrients (phosphate, nitrate), chlorophyll-a, and pH were collected every six

hours and in conjunction with all neuston net tows during the cruise track (Table 3). As part of

near-to-offshore transects and shipek grabs stations (see below) water samples were collected to

measure coliform bacteria as a indicator of human impacts in coastal settings (Table 4).

Additional Hourly Observations included the enumeration of seabirds, sea turtles, flying fish,

marine mammals, and floating plastic debris. Observations occurred only during daylight hours

0700-1900 for a period of 6 minutes each hour. Periodically, opportunistic sightings were also

recorded when notable megafauna or marine debris were present. Data available upon request.

But for the occasional eddy associated with the Almeria-Oran front and the Straits of Gibraltar

surface currents along the C269 cruise track were weak (< 500mm/s, or 1.0 knot) and variable in

direction. Regional examination of surface currents highlight the presence of eddies and

meanders near constricted passages or islands (Figure 3).

The density structure of the water column (maximum depth 2000 m) was determined using a

Seabird CTD with attached dissolved oxygen sensor (11 stations, Table 5). Vertical profiles of

chlorophyll-a and nutrients (phosphate, nitrate) and pH were determined using a 12-bottle

carousel equipped with a Seabird CTD and three auxiliary sensors: in situ chlorophyll-a

fluorescence, dissolved oxygen, and photosynthetic active radiation (PAR) (15 stations, Table 6).

Four water masses were tracked as revealed by profiles of temperature, salinity, dissolved

oxygen, and chlorophyll-a fluorescence as well as two sub-surface eddies or ‘meddies’ once

outside the Mediterranean (Figure 4a-d).

Surface plankton assemblages along with marine debris and tar balls were sampled regularly

with a neuston net (37 stations, 335 µm mesh, Table 7). Sub-surface plastic and zooplankton

communities were collected with a Tucker Trawl at a shallow depth of 5-10m (8 stations, 335

μm mesh, Table 8). Plankton assemblages at discrete depths (200m) were collected using a 1m

diameter Meter net (1 stations, 335 μm mesh, Table 9). In combination these myriad net

deployments reveal the vertical and horizontal distribution patterns of several nektonic

organisms (lantern fish – Family Myctophidae, and gelatinous organisms >2cm – i.e Pelagia

noctiluca), meroplanktonic larvae including spiny lobster (phyllosoma) and eels (leptocephali),

the marine insect Halobates, pteropods, and the density (mL/m2), diversity (i.e. Shannon-Weiner

index) and taxonomic composition of the aggregate zooplankton community in relation to

numerous environmental parameters (Table 10).

Routinely a phytoplankton sample was collected with a surface (~1-3m) drifted net (15 stations,

30cm frame, 63 µm mesh, Table 11) to determine the taxonomic composition of phytoplankton,

foraminiferans and radiolarians.

Eleven sediment samples were collected using a shipek grab ranging in depth from 40 to 340m

and sieved fro grain size analysis and sorted for benthic organism diversity related to human

impact as deduced via coliform bacteria counts (Table 12). Additional data available upon

request.

Final scientific work conducted aboard ship was the routine deployment of a secchi disc (14

stations, Table 13) to estimate the 1% light level.

Additional CTD, CHIRP, ADCP and biological data not reported here are available on request

through Sea Education Association (SEA) and the Chief Scientist. The information in this report

is not intended to represent final interpretation of the data and should not be excerpted or cited

without written permission from SEA.

As part of SEA’s educational program, undergraduates conducted independent oceanographic

research during the cruise. Projects explored regionally, relevant topics in the disciplines of

physical, chemical, and biological oceanography (Table 14). Student research efforts culminated

in a written report and public presentation to the ship’s company. These papers are available on

request from SEA.

Duplicate station numbers indicate multiple oceanographic deployments that either occurred concurrently in the same location

or were deployed sequentially in the same general location after the vessel was hove to. General Locations are categorized by

traditional oceanic biomes or significant geologic feature. Abbreviations for oceanographic equipment deployed are: NT –

Neuston Tow, TT – Tucker Trawl net, MN – Meter Net tow, PN – Phytoplankton Net, CTD – conductivity, temperature, and

depth profilers, HC – Hydrocast with 12 Niskin bottles and CTD, SG – Shipek Grab, and SD – Secchi Disc. * These stations

occurred in Moroccan waters (EEZ) and were for training purposes only, no data was collected.

Surface water samples were collected using a clean, seawater flow-thru system (intake ~ 1-3m depth) with in-line

temperature, salinity and in vivo chlorophyll-a, fluorescence sensors. Discrete water samples were collected for

phosphate (PO4) analysis, measured by colorimetric analysis with an Ocean Optics Chem2000 digital

spectrophotometer; and extracted chlorophyll-a (Chl-a) concentrations, measured with a Turner Designs Model 10-

AU Fluorometer following methods outlined in Parsons, Maita and Lalli, A Manual of Chemical and Biological

Methods for Seawater Analysis, Pergamon Press 1984. Chlorophyll-a samples were filtered through 0.45 µm filters.

A blank space indicates that no sample was collected for that analysis.

Coliform bacteria colony counts were based on EPA Coliquant Test kits incubated at ambient air temperature for two days. Plates were photographed and colony

growth was counted under a dissecting microscope at 24hrs and 48hrs. Surface water samples were collected using a clean, seawater flow-thru system (intake ~

1-3m depth). Near-bottom and sub-surface water samples collected with niskin bottles rigged above shipek grabs and with hydrocast deployments.

Tow area was calculated using distance in meters between successive (every minute) GPS positions. Net opening was 1.0 m wide by 0.5 m tall with a net mesh

of 335 µm. Zooplankton density is recorded as wet volume displacement per tow area (ml/m2). Eel larvae (leptocephali), spiny lobster larvae (phyllosoma), and

Lantern fish (Family Myctophidae), were sorted from net contents and recorded as numbers caught per tow. Micronekton, gelatinous micronekton, and plant

material was removed using a 1 cm mesh sieve and biomass (ml) or length (cm) was recorded. Floating plastic was also removed from net contents, sorted as

pellets (none collected entire cruise) or pieces and recorded as numbers collected per tow. Floating tar was sorted from the nets contents and recorded present or

absent (none collected entire cruise). Qualitative description of micronekton removed from the zooplankton biomass is provided, and when available biomass

(ml) and length (cm) of specimens are recorded
