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
will have on these species, they are an abundant component of the marine community
in the study area and abundance trends should be monitored.

A species was considered to be"present", if it occurred only insmall numbers and was usuallydifficult to locate.
A species was considered to be"common", if it was a commonpart of the flora and fauna andwas easily observed and located.
ABUNDANT (A) A species was considered to be"abundant" if it occurred in unusually large numbers and dom .inated the flora or fauna of aparticular site.
