This survey has demonstrated that the marine community at Point Lepreau is

typical of the exposed coast of the outer Bay of Fundy.

Perhaps the most serious shortcoming in this work was the timing of the field

season. A number of benthic species are not present or difficult to find during the

winter season. In part this has been overcome by the inclusion of additional summer

data from MRA files and we feel that we have established a good overview of both

summer and winter communities in the study area.

Our specific recommendations for subsequent monitoring are:

1. TIMING. We recommend that future field work be carried out during the period

from May-do<September. There are two reasons for this. Firstly, the marine com

munities are complete and flourishing during this period and thermal effects will

be most obvious when the water temperature is highest. Secondly, there is no

guarantee that winter field work will be completed. The winter of 1979-80 was

sufficiently mild with enough calm days to allow completion of the work. This is

not true during the "average" Fundy winter when prolonged periods with high

winds prevent successful field operation, particularly on the exposed coast. In ad

dition, survey costs are considerably greater during the winter.

2. ADDITIONAL WORK_ At a minimum, summer aerial mapping of the intertidal

area should be made at low water during spring tides. These photographs should be

used to determine the distribution and abundance of marine organisms associated

with rockweed. We believe that such data will provide the easiest, most rapid method

of assessing changes in the area. In addition, this is a relatively inexpensive way of

monitoring impacts should funds be limited in the future.

While the transect data provided here will be suitable for monitoring population

changes in the future we believe that a grid should be established around the out

fall and that the spatial distribution of principal macrofauna should be mapped.

Like the aerial mapping of the intertidal area, this should provide baseline data for

rapid, relatively inexpensive, assessment of subtidal benthic changes. As outlined

in the text, species of particular interest in this regard are: Ha/ichondria sp, Tubularia

sp. Balanus balanoides, Gammarus ocean;cus, Mytilus edulis, Acmaea testudina/is, Strongylo

centrotus droebachiensis, bryozoans. As indicated by our work at Coleson Cove, the

RECOMMENDATIONS

appearance of Flustra fo/iacea should be considered an indicator of major enviro

mental changes.

3. MONITORING PERIOD. We believe that this marine monitoring program should

be carried out annually after start-up of the nuclear plant. Safety of field personnel

should be insured by a pre-survey assessment of radiation levels in the primary

study area.

1.1 INTRODUCTION

This report is the first of two volumes. The principal objective of this work

was to obtain baseline ecological data for evaluation of the impact of the thermal

effluent from the Point Lepreau Nuclear Generating Station on local marine flora

and fauna. MRA had carried out a benthic marine survey at Coleson Cove in 1974

and, as a secondary objective, a comparative survey was carried out during this

study with a view to applying the results to the Point Lepreau outfall. Volume 2

covers the work carried out at Coleson Cove. This volume deals with the work

carried out at Point Lepreau.

1.2 BACKGROUND

Although it is expected that no significant or obvious environmental damage

will result from the discharge of heated water, and its constituents, from the Point

Lepreau nuclear generating station outfall, it is possible that sublethal effects may

occur as a result of the influence of heat, biocides and/onadionuclides. Changes

in such biological functions as growth, respiration rate, reproduction and behav

iour are possible, and could manifest themselves in altered species diversity and

community structure in populations of organisms exposed to the heated effluent.

Because benthic organisms are relatively immobile and because they form char

acteristic assemblages related to specific water quality parameters, these organisms

are ideal as indicators ofecolbgical effects. Effects related to effluents from the

Point Lepreau cooling water system should manifest themselves in altered species

composition in the vicinity of Point Lepreau which will be used by the Working

Group on Point Lepreau Environmental Monitoring in developing a baseline against

which future post-operational conditions may be compared.

Some baseline work has already been done in relation to the Coleson Cove ther

mal generating station. Although this work was primarily qualitative in nature, it

would be useful to reoccupy the stations established for this baseline work, to de

termine whether there has been an effect due to the operation of the Coleson Cove

station. This information would be useful background for carrying out the Point

Lepreau study.

INTRODUCTION

1.3 OBJECTIVES

To assess the effects of the Coleson Cove thermal generating station on benthic

communities at Coleson Cove, N. B.

To provide samples of Mytilus edulls from Coleson Cove for stable isotope ana

lysis by the Dept. of Fisheries and Oceans. This analysis will provide information

on historical temperature fluctuations at Coleson Cove.

To determine the population density of each species of benthic organism at

four stations along each of six transects in the vicinity of the Point Lepreau nuc

lear generating station. In addition a qualitative evaluation of each transect will

be made.

1.4 STATEMENT OF WORK

Transects established at the Coleson Cove thermal generating station by Mar

ine Research Associates Ltd. will be reoccupied to determine whether changes in

benthic organisms have occurred after four years of operation at that station.

Since the original surveys were done in a qualitative fashion, only qualitative aha

lysis of change will be possible. The changes will be considered in terms of the

expected variation due to natural conditions as well as those related to local in

creases in ambient temperature.

Samples of Mytilus edulis will be coll~ted from each of three locations (shal·

low, mid and deep water) along each transect at Coleson Cove. These will be pre·

served and delivered to the Bedford Institute of Oceanography for stable isotope

analysis. (See Killingley and Berger, Science, Vol. 205,13 July, 1979).

Six transects near the Point Lepreau outfall will be established in consultation

with the Scientific Authority. Four transects will be within the area of influence

of the cooling water outfall; two will act as controls and be outside of this zone.

Transects will be established such that, where possible, all will traverse similar

bottom types in running from the intertidal zone into the subtidal zone to a depth

of approximately 15 meters below MLW.

Benthic biota will be sampled both qualitatively and quantitatively along the

six transects. Qualitative assessment will involve a visual count of all organisms

along each transect from the intertidal zone to 15m below MLW. Quantitative

sampling will be done at four stations along each transect (intertidal, 5 metres, 10meters and 15 meters below MLW) by collecting organisms from within a number

of 0.25 m square grids. The number of grids per station will be determined by a

"catch for effort" analysis to be done on site once prior to initiation of the samp'

ling program. Details of this s'ampling method will be developed in consultation

with the Scientific Authority.

Specimens will be preserved and identified to species where possible. The

number and total dry weight of each species will be determined.

1.5 REPORTING

A report outlining the results of the study must be submitted to Enviroment·

al Protection Services within one month of completion of the survey and not

laterthan March 31, 1980.

The report should describe in detail:

1) the results of the Coleson Cove evaluation considering both natural and man·

made variations;

2) the transects selected for sampling including a qualitative description of bot·

tom type at each station; and

3) the number and dry weight of each species of orga~ism collected at each sta·

tion.

2.1 SUBTIDAL SAMPLING TECHNIQUES

All divers were equipped with "wet" suits and accessories or constant volume

dry suits (UNISUITS). The Unisuits proved to be invaluable during winter oper

ations and allowed our divers to operate in extremely cold waters with much the

same comfort as in summer. Single 72 cu. ft. air cylinders with single hose Posei·

don regulators were used on all dives. Recordings of depth were taken from Aqua

Lung underwater depth gauges checked against measured depths. Underwater

observationsw"ete recorded in pencil on Appleton Underwater "Ascot" paper.

Spot dives were conducted by moving into shallow water at a predetermined

site. Divers entered the water and roamed widely over the bottom at various depths

recording the substrate, abundance of resident organisms, water temperature, and

depth relationships encountered. Where quantitative data were required, a quadrate

was placed at random on the bottom and the numbers of animals within this square

were counted. Upon completion of the dive, the diver was debriefed using a special

Site Data Form.

Transects were run where detailed information on a site was required as shown in

Figure 2.1. The dive team consisted of two divers, a dive-tender, and boat operator

debriefer. The divers were responsible for examination of the transect area, record

ing of data, and the collection of specimens, The dive-tender was responsible for

deploying and picking up the diving team and insuring their safety on the surface.

The boat operator-debriefer was responsible for maintaining the support vessel, recor

ding the dive site data, and debriefing the divers at the conclusion of each dive to

insure that the maximum amount of information was obtained. On steep cliffs run

ning into deep water, one end of the transect line was anchored at the base of the

cliff or, if possible, at the low water mark and laid across the bottom at right angles

to the shore and anchored to the outer end. When currents permitted, the survey ves

sel was anchored to the other end of the transect line. When this was not possible,

both ends of the transect line were marked with a buoy.

Divers entered the water at the anchor line or outer marker buoy and proceeded

to dive to the other end of the transect line. Numbered markers on the transect line

indicated each of thirty-five stations at 3 meter intervals. At each station, the diver-re

corder recorded the depth, substrate, and organisms. Where quantitative data were

MATERIALS AND METHODS

required a quadrate was placed at the station and counts were made within the

square. Any distinct change in substrate or faunal composition which occurred be

tween statiOns was also recorded. This activity was carried out along the length

of the transect line to the high water mark where possible. Where this was not pos

sible due to the steepness of a cliff, observations were made from low water. When

data were required beyond the outer limit of the transect line, spot dives were made

at various depths to a maximum of 100 feet_

Where visibility was at or near zero, all observations and records were made

using underwater lights.

2.2 INTERTIDAL SAMPLING TECHNIQUES

The survey team usually consisted of two individuals; the sampler, who examined

the substrate, made identification of organisms encountered, and collected specim

ens when necessary and a recorder who made field notes on the substrate and organ

isms encountered at each sampling station.

A 100 meter transect line was used. Starting at the high water mark, the trans

ect line was laid across the substrate on a fixed magnetic bearing from the starting

shore position. When the substrate under the transect line had been examined at

the required stations, the line was moved to the next interval on the same bearing

and the process was repeated until low water was reached.

4.1 INTRODUCTION

Physical descriptions of the study area have been given by Marine Research

Associates Ltd., MacLaren Atlantic Ltd (1977) and others. For references purposes,

the description provided by MacKay (1979) is reproduced here.

4.2 GEOLOGY

Since substrate largely determines the distribution and abundance of benthicorganisms, the geological character of any area is usually a primary influence onthe marine community. This is particularly true at Point Lepreau where a variablebedrock geology produces distinctive variations in marine substrates.

As can be seen in Figure 4.2.1, there are nine principal geological formations in thestudy area. However, because of the manner in which these formations strike the coast,the study area is divided into two distinct areas:

AREA A· In this area, bedrock is dominated by hard erosion resistant igneous andmetamorphic rocks. This area dominates the western half of the study area from themouth of Lepreau River to Beaver Harbour.

AREA B - Area B extends from Lepreau River east to Musquash Harbour. It isdominated by erodable sandstone, conglomerate and shale.

The significance of th.ese two major formations is considerable in terms of the marine community. The character of intertidal and subtidal bottoms from Maces Bay tothe east is influenced by sand derived from the erodable sedimentary bedrock. As canbe seen in Figure 4.2.1, sedimentary deposits extend westward to Seeley's Covewhere sand deposits are probably formed by current borne sand particles. Tothe west, hard volcanic rocks dominate most of the exposed coast and, as is discussed later, assemblages of plants and animals are similar to those found onhard exposed coast elsewhere in the mouth of the Bay of Fundy.

Topographically, the coastline is rocky and rugged with elevations reaching 150feet. However, there are numerous inlets, bays and harbours (Deadman's'Harbour,Beaver Harbour, Pocologan Harbour, New River Harbour, Lepreau Harbour, LittleLepreau Basin, Dipper Harbour, Chance Harbour and Musquash Harbour) and it isat these localities where most of the extensive intertidal mudflats are found. Estuarinespecies occur commonly where freshwater streams flow into ambayments but suchareas are generally restricted.

~

PHYSICAL DESCRIPTION4.3 WIND

Wind has a major influence on the distribution and abundance of marine organisms. Species which are unable to remain attached to their substrate during stormsare generally restricted to sheltered localities. As a result, pfaht and animal assemblages will vary, on the same type of substrate, from locality to locality on thebasis of exposure. Since much of the sttidy area is openly exposed to severe stormscreated by high winds from the west, south and east, faunal diversity on the exposedshore is somewhat reduced, but typical for exposed coasts.

4.4 CURRENTS

Life-giving elements, oxygen and nutrients are borne by currents and distributed to organisms throughout the Bay of Fundy. As a resiJlt, regional and local patterns playa significant role in determining the biomass of organisms which anygiven area can support

Fifteen years of data collection at hundreds of sites in the Bay of Fundy haveled us to believe that any concentrating mechanism (passages, drop-offs and upwellings) leads to localized elevations of productivity.

The physical characteristics of some areas are such that these concentrating mechanisms are common and help to shape the biotiC characteristics of the area. The area between Deer Island and Campobello is the most significant example in the Bay of Fundy.This area supports an unusual diversity and abundance of marine organisms due inlarge measure, we believe. to an elevated level of local productivity created by theadded contribution of benthic organisms to the plankton base.

The study area does not have any major areas where current borne food and nutrients are concentrated to any major degree. Several areas demonstrate this phenomenonto a limited extent: the passages between Red Head and Pocolo~an Island and aroundthe Brothers and the area at the tip of Point Lepreau. Other than these localities,the area exhibits reasonable homogeneity in its biota and, presumably, receivesessentially the same level of nutrients and food at most localities. Nevertheless, theMaces Bay area supports a relatively high diversity and abundance of benthic organisms.MacLaren Atlantic Limited (1977) indicated that plankton levels appear greater to thewestof Point Lepreau. This is possibly related to eddying and a greater surface area inMaces Bay supporting a higher density of benthic organisms than areas to the east.

Known current patterns are shown in Figures 4.4.1 and 4.4.2. As can be seen current data are very IImited,being'restricted to the immediate vicinity of Point Lepreau.It is essential that additional data be collected, since MRA's field observations suggestthat during both ebb and flood, waters move rapidly parallel to the coast andpollutants originating at Point Lepreau may not be maintained locally but may, infact, have greater influence on locafities many miles removed.

4.6 FRESHWATER SOURCES

Freshwater has a significant influence on the marine environment and, where.-salt and fresh waters mix, the area supports a distinctive assemblage of organisms

which demonstrate a tolerance for wide salinity fluctuations. As shown in Figure

4.6.1, there are no major rivers influencing the area. Mo~t freshwater flow comes

from small brooks and streams. As a result, estuarine habitat is restricted largely

to Lepreau River and Little Lepreau Basin.

4.7 PRINCIPAL MARINE HABITATS

[

r[

Based on the physical characteristics of the study area described in the pre

vious section, we would identify the following principal marine habitats as shown

in Figure4.7.1.

11 THE EXPOSED ROCKY SHORE. Since most of the coast is openlyexposed to winds and storms, the principal habitat of the study areais exposed rocky shore. However> because of the geological charactelof the area, this habitat must be subdivided as follows:

[SECTION 1 : EXPOSED ROCKY SHORE IGNEOUS SUBSTRATESECTION 2: EXPOSED ROCKY SHORE·SEDIMENTARY SUBSTRATE

2) EMBAYMENTS. Seven major embayments occur in the study area.These are characterized by intertidal mud, sand or a combination ofmud and sand.

5) PELAGIC HABITAT. The open water areas of the study area soplJon adiversity of pelagic organisms ranging from planktonic [01 ms 10 mammals.

4) DEEP SUBTIDAL OR BATHYAL HABITAT. Much of the area is dominated by deep subtidal habitat which must be considered in a monitoring program.

61 MINOR HABITATS. Several minor habitats such as sand. C<.li)IJle andshingle beaches and marshes occur throughout the aree. I" the followinganalysis of the ~rincipfll h~hitats Ihesp rltP. cOrlsidl'led ciS [llllll}! cornponelltsof l!lPSf' Ilt-l!llldl<:

13

ESTUARIES. Although there are no major estuaries in the study area.Lepreau Harbour and Little Lepreau Basin exhibit estuarine cllarac1eristics which may be important in terms of a monitoring program.

3)

Depths in the study area vary widely. Intertidal areas are extensive in Maces Bay.

Similarly, this Bay has an extensive shallow subtidal area and,just offshore,depths

reach several hundred feet. As a result, the study area has suitable habitat for a wide

range of organisms and this is reflected in the presence of intertidal, shallow, sub·

tidal bathyal and pelagic species.

DATA ANALYSIS

5.1 INTRODUCTION

The primary objective of this study was to provide qualitative and quantitative

data which can be used in the future to determine the impact of heated cooling

water from the Point Lepreau Nuclear Generating Station on the benthic flora and

fauna in the vicinity of the outfall.

All available data in MRA files have been added to those data obtained during

this study in an effort to present the most complete picture of floral and faunal

distribution and abundance. The locations of additional study sites used are shown

in Figure 5.1. 1.

5.2 DISTRIBUTION AND ABUNDANCE OF FLORA AND FAUNA

Table 5.2.1 summarize distribution and abundance data for all transects, study

sites and quadrate samples in the study area.

5.3 ECOLOGICAL POSITION OF THE STUDY AREA

An analysis of MRA's field data shows a decrease in species diversity along the

New Brunswick shore of the Bay of Fundy. The most dramatic decrease in species

appears to occur along the stretch of coast between Point Lepreau and Lorneville.

When compared with other areas in the Bay, the study area shows close affin

ities with the exposed coast to the west (Figure 5.3.1). Species composition and

diversity are very similar. On the basis of this comparision, we would classify the

study area as an exposed coastal marine community characterized primarily by

Cnidarians, Molluscs, Annelids, Arthropods, Echinoderms and plants.

5.4 SEASONALITY

Since the study was carried out during the winter season many species may

appear t~absent or less abundant than would be the case during the summer.

All additi:;al field stud'( data (Figvre 5.1.1) were collected during the summer of

1978 and these data can be used to provide a rough indicator of anticipated dis-...... .. .tributio~d abundanc~ .

" '.

~..5.5 INDICATOR SPECIES AND SUBSEQUENT MONITORING

Examination of the transect and quadrate data as well as the literature shows

that numerous marine species occur in the study area. Many of these species. how

ever, OCC1,lf in small numbers in scattered localities. Others are characteristic to the

area and should be su.itable for primary evaluation of impacts. Aerial monitoring

of rockweed distribution, for example, should provide a rapid method of determin·

ing intertidal effects. For other species, transects and quadrates can be re-run to

determine changes.

Species which we feel should be given close attention throughout the monitor·

ing program are:

SPONGES

1) HALICHONDRIA AND RELATED SPECIES. - The Crumb·of-bread sponge

occurs commonly both intertidally and subtidally. Our experience at Coleson

Cove suggests the presence of this species may indicate elevations in temperature.

Annual checks of the distribution of these species in relation to the outfall should

be made.

CNIDARIANS

1) TUBULAR IA SP. - Tubularia occurs most abundantly during the summer months.

Elevated temperatures may produce greater winter abundance of this species.

ARTHROPODS

1) BALANUS BALANOIDES AND GAMMARUS OCEANICUS - While barnacles

and gammarids can withstand wide temperature fluctuations, monitoring of fixed

populations may produce significant changes in abundance.

MOLLUSCS

~

r

PLANTS.. '.,

.~1) INTERTIDAL SPECI ES - Populations of Mytilus edulis. Acmaea tesrudinalis and

Littorina (3 species) should be monitored to determine population changes.

24

1) ROCKWEEDS - Both Ascophyllum nodosum and Fucus sp provide essential cover

for intertidal animals. Physical removal of this cover will reduce populations of peri

winkles, dogwhelks, limpets, gammarids, etc. Aerial photographs provide the best

method for monitoring spatial changes in distribution and abundance. Baseline

photographs should be taken during the summer, just prior to start·up, and on

the same date each subsequent year.

2) L1THOTHAMNION Sp, CORALLINA AND RELATED SPECIES - Encrusting

Coralline algae are universally present on rock bottom in the study area. Mortality

i~ these species is readily determined by color changes from pink to white. Annual

checks of Lithothamnion near the outfall could provide a rapid indicator of major

impacts from heat or biocides.

ECHINODERMS

1) STRONGYLOCENTROTUS DROEBACHIENSIS - Our experience with sea urchins

suggests that they are unable to survive elevated temperatures. Abundance of this

species should be monitored in relation to the outfall.

BRYOZOANS

1) ALL SPECI ES - While we have no data to indicate what effect elevated temperatures
