This report is the second of two volumes. The principal objective of this workwas to obtain baseline ecological data fo r evaluation of the impact of the thermaleff luent from the Point Lepreau Nuclear Generating Station on local marine floraand fauna. MRA had carried ou t a benthic marine survey at Coleson Cove in 1974and, as a secondary objective, a comparative survey was carried ou t during thisstudy with a view to applyin9 the results to the Point Lepreau outfall. This volumecovers the work carried ou t at Coleson Cove.

1.2 BACKGROUND

Although it is expected that no significant or obvious environmental damagewill result from the discharge of heated water, and its constituents, from the PointLepreau nuclear generating station outfall, it is possible that sublethal effects mayoccur as a result of the influence of heat, biocides andlor radionuclides. Changesin such biological functions as growth, respiration rate, reproduction and behaviour are possible, and could manifest themselves in altered species diversity andcommunity structure in populations of organisms exposed to the heated effluent.

,Because benthic organisms are relatively immobile and because they form characteristic assemblages related to specific water quality parameters, these organismsare ideal as indicators of ecolo'gical effects. Effects related to effluents from thePoint Lepreau cooling water system should manifest themselves in altered speciescomposition in the vicinity of Point Lepreau which wi ll be used by the WorkingGroup on Point Lepreau Environmental Monitoring in developing a baseline againstwhich future post-operational conditions may be compared.

Some baseline work has already been done in relat ion to the Coleson Cove thermal generating station. Although this work was primarily qualitative in nature, itwould be useful to reoccupy the stations established fo r this baseline work, to de-termine whether there has been an effect due to the operation of the Coleson Covestation. This information would be useful background fo r carrying ou t the PointL:epreau study.

2.1 SUBTIDAL SAMPLING TECHNIOUESAl l divers were equipped with "wet" suits and accessories or constant volume

drysuits (UNISUITS). The Unisuits proved to be invaluable during winter operations and allowed our divers to operate in extremely cold waters with much thesame comfort as in summer. Single 72 cu. ft. air cylinders with single hose Poseidon regulatorswere used on all dives. Recordings of depth were taken from AquaLung underwater depth gauges checked against measured depths. Underwaterobservations were recorded in pencil on Appleton Underwater "Ascot" paper.

MATERIALS A

Spot dives were conducted by moving into shallow water at a predeterminedsite. Divers entered the water and roamed widely over the bottom at various depthsrecording the substrate, abundance of resident organisms, water temperature, anddepth relationships encountered. Where quantitative data were required, a quadratewas placed at random on the bottom and the numbers of animals within this squarewere counted. Upon completion of the dive, the diver was debriefed using a specialSite Data Form.

Transects were run where detailed information on a site was required as shown inFigure 2.1. The dive team consisted of two divers, a dive-tender, and boat operatordebriefer. The divers were responsible fo r examination of the transect area, recording of data, and the collection of specimens, The dive-tender was responsible fordeploying and picking up the div ing team and insur ing their safety on the surface.The boat operator-debriefer was responsible fo r maintaining the support vessel, recording the dive site data, and debrief ing the divers at the conclusion of each dive toinsure that the maximum amount of information was obtained. On steep cliffs running into deep water, one end of the t ransect l ine was anchored at the base of thecliff or, if possible, at the low water mark and laid across the bottom at right anglesto the shore and anchored to the outer end_ When currents permitted, the survey ves-sel was anchored to the other end of the transect l ine. When this was not possibleboth ends of the transect line were marked with a buoy.

Divers entered the water at the anchor l ine or outer marker buoy and proceededto dive to the other end of the transect l ine. Numbered markers on the transect l ineindicated each of thirty-five stat ions at 3 meter intervals. At each station, the diver-recorder recorded the depth. substrate, and organisms. Where quantitative data were

required a quadrate was placed at the stat ion andsquare. Any distinct change in substrate or faunaltween stations was also recorded. This activity waof the transect l ine t o the high water mark wheresible due to the steepness of a cliff, observationsdata were required beyond the outer l imit of theat various depths to a max imum of 100 feet.

Where visibility was at or near zero, all observusing underwater lights.

Southern New Brunswick was subject to glaciation during the Pleistocene andthe direction of glacial striations indicates that ice movement was southeasterly(Subhas, 1970). During deep water spot dives at the mouth of Musquash Harbour,numerous large rounded boulders, up to approximately 15 feet in diameter, were

Drainage of fresh water into the study area is primarily from the Musquash Riveron the wes tand the Saint John R iver on the east. Numerous small streams makeminor contributions along the extent of both Musquash and Lorneville Harbours.However, it is, undoubtedly, the larger rivers which contribute most to the ecological characteristics of the study area, particularly through the deposition ofsediment intertidally and subtidally, their contribution of freshwater and transportof pollutants from Saint John, N.B.

General shore types have been detailed by Thomas (1973) under the categoriesof rock, boulder, sand and shingle, mud and saltmarsh. In general, these agree withour observations. However, we have altered our definitions somewhat to incorporate subtidal substrates. The distribution of shore types in the study area is illustrated in Figures 4.2.3 and 4.2.4. Using the data available f rom o ur subtidal transects, we have included a preliminary representation of subtidal bottom types in theLorneville Area.4.3 T I DA L D A TAThe Bay of Fundy is well known fo r the magnitude of i ts t idal range. Indeed, it

is this large t idal fluctuation which partly accounts fo r the unique ecological aspectof the Bay. By producing extensive intertidal areas which are exposed twicedaily,habitat is provided fo r diverse and abundant intertidal organisms. The gametes andlarvae of many of these intertidal plantsand animals form an important part of therich plankton base of the Bay. It is this high level of plankton production whichresults in extremely high productivity and, consequently, a valuable fishery.

Similarly, t idal range greatly effects the development of marine-oriented industries and the force and pattern of t idal currents must be well understood ifintelligent decisions are to be made regarding the effective dispersal of effluentf rom any coastal industrial operation.

Neu (1973) has presented a comprehensive report on the hydrodynamics of theLorneville area in the original Lornevil le Environmental Impact Study. However,

On a seasonal basis, it was fel t that the effects would be as follows: 1) Summer.Moderate volumes of very warm, freshwater would flow along the surface, over thecolder, more saline, seawater. 2) Fall. Freshwater outflow would diminish with freezing temperatures. The temperature of freshwater reaching th e Bay would drop tovalues near that of the seawater resulting in more mixing and confused salinity patterns. 3) Winter. Freshwater inflow would be at its lowest, resulting in very low surface temperatures and higher salinity values as seawater reaches further into SaintJohn Harbour.

A graphic transect by transect comparison of the distribution and abundanceof marine organisms at Coleson Cove in 1974 and 1980 are presented in the DataFile section of th is report. Table 6.1.1 provides a species by species tabulation aswell as comments on population changes.6.2 INTERTIDAL IMPACTS OF THE HEATED EFFLUENT

rr[[[[

lll

Most intertidal marine organisms can withstand wide temperature fluctuationsand no major changes were anticipated. A comparative review of intert idal species(Table 6.1.1) confirms that, in general, no changes are apparent which could notbe explained by seasonality or variations in sampling techniques. In fact, In 1974the area in front of the generating plant had been expanded w it h fi ll a "d tl"s areahas had good recolonization by littoral organisms.

6.3 SUBTIDAL POPULATION CHANGES

On the whole the species composition of the area is much the same now as iIwas in 1974 and most subtidal organisms do no t show major changes in distributionand abundance which cannot be explained by seasonality or variations in samplingtechnique. Nevertheless, six species show ,ignificant changes In distribution and abundance which suggests to us that a shift in the ecological parameters of ColesonCove is taking place. In general, we believe that the study area is taking on characteristics of marine communities found at the mouth of Lornevil le Harbour and at St.Martins. We would characterize this community as having low species diversitY andabundant populations of Flustra fol iaeea, Halichondria sp., various bryozoans, Anomia.Haliclona OCU/eita, Crepidula sp. r Balanus sp. and PaguTlls sp. In general echinoderms,Brachiopods and molluscs are absent or occur in low numbers.

Specifically, changes at Coleson Cove are as follows:1) Halichondriasp. was of spotty occurrence (present at BT8 and absent at BT7,9 and 10 in 1974) . It is now present to abundant on all t ransects in Coleson Cove
