ABSTRACT
Linda Ives Tyndall. SEASONAL AnSTTNDANCE .AND DISTRIBUTION OF PHYTOPLAl-niTON
IN THE ajRJlITUCK SOUND. (Under the direction of Dr. Graham J. Davis)
Department of Biology, June, 1980.
Phytoplanhton abundance and distribution in Currituck Sound, N. C.
v,v.re studied through analysis of samples taken from 13 stations at
approximatel37 monthly intervals from November 1977 through October 1978.
Of the phyla represented, the cyanophytes had the greatest density. A
total of 204 taxa were found. These represented 67 genera, 14 orders,
and 6 phyla. Ma:-;imum cell numbers occurred in August, 1973 and
maximum biomass in May, 1978. In August, the phytoplankton population
consisted of a large number of small species such as blue-green algae
with volumes of only a few whereas, the May biomass peak
consisted of larger forms.
The major portion of the phytoplankton in the water col’umn
probably originated through resuspension of sediments through wind
action and sloughing of epiph^ytic forms from submersed macrophytes. A
greater Cyanophyta population existed in the northern sound and a
larger diatoia population in the southern sound. Possible factors
involved were shallovcness of the soraid, restriction of ’water circulation
by the marsh islands in the middle reach of the sound, and differences
in morphometry and salinity for the two areas. Only 22% of all algal
species v'ere eupl.anktonlc types.

INTRODUCTION
Background and Objectives
For many years Currituck Sound has been an important bass
fishery area, a temporary home for waterfowl, and a summer recreational
area. Generations of local residents have earned their livelihood
through commercial fishing and other related activities. Sincock (1965)
cited letters from local residents to the District Engineer of the U. S.
Army Corps of Engineers in Norfolk, Virginia. These letters recalled
a crab factory on Currituck Sound during the late 1800's with as many
as 32 fishing crews that harvested an average of 1000 pounds per week
per crexi. Presently, commercial fishing is not economically important.
An early study of the sound in 1897 viewed the closing of the new
Currituck inlet in 1828 as one of the most important geological events
with ecological consequences occurring along the Atlantic Coast in
recent times (Weiland, 1897 cited in Sincock, 1965). Prior to the
closing of this inlet, extensive oyster beds existed in the sound.
The closing of this inlet led to the conversion of a body of shalloxí
salt xv^ater to mildly brackish water. Oysters died leaving only
shells as reminders of their past importance. Welland also noted
changes in vegetation that attracted numerous species of ducks and
stated that fresh water fish replaced salt water species (Sincock, 1965)
The first recorded observations of vegetation of the Currituck
Sound xiere by McAtee (1919) in 1909 and the fall of 1918. He reported
sago pondx/eed (Potamogetón pectinatus L.) as the dominant plant. In a
report to the U. S. Senate in 1929 (cited in Sincock, 1965), Jadwin,
2
O’Connor, and Jewett testified before the committee that there had been
a decline in the number of ducks visiting the sound since 1920. The
greatest decline had been in the northern soimd.
The apparent effects of dredging of the Albemarle and Chesapeake
Canal, of the North Landing River and in the general vicinity of the
Currituck Sound from 1914 to 1923 led to an investigation of the factors
associated with the decline of aquatic plants in Back Bay and Currituck
Sound waters from 1926 to 1930 by Bourn (1932). An important aspect of
Bourn's work was the development of methods of reseeding barren areas
of the sound. Prior to the dredging activities, the water had been
reported clear (Bourn, 1932). Bourn described these waters as
"extremely turbid" and concluded from his investigation that turbidity
was the major factor responsible for the destruction of submerged plants.
He stated that the primary source of turbid X\7ater was from the Albemarle
and Chesapeake Canal (the intracoastal waten^ay) that connected Norfolk
Harbor with North Landing River. Until the canal was sold to the
Federal Government in 1912, the locks at Great Bridge, Virginia prevented
movement of water do^m the canal. From this time until August, 1932 the
locks xære left opened. In August 1932, new locks were put into operation
at the urging of Bourn and others. Bourn surmised that increased turbidit3’’
of Currituck Sound was related to city sewer effluent from southeastern
Virginia transported by way of the intracoastal waterway. In a survey of
Back Bay and Currituck Sound in the 1940's. Bourn noted there were
improvements in waterfowl and fish food conditions (Sincock, 1965).
Dickinson (1958) rated the growth of aquatic plants as good in most
areas with wildcelery (Vallisneria americana L.), sago pondweed
and widgeongrass (Ruppia marítima L.) the predominant species. It was
not until a cooperative study by the Bureau of Sports Fisheries and
Wildlife, the North Carolina Wildlife Resources Commission, and the
Virginia Commission of Game and Inland Fisheries that a thorough
quantitative measurement x^as made of the aquatic vegetation, x/aterfov?!,
and fish populations in Currituck Sound. This report listed bushy pond-
weed (Najas guadalupensis Sprang. (Morong)), muskgrass, which included
Chara and Nitella, and sago pondweed as the most abundant species of
aquatic macrophytes (Sincock, 1965). Greater turbidities during
the period of November through April x^ith xílnds from the north and
northeast were also reported. Harmful effects to aquatic vegetation
resulted from these periods of increased turbidity.
Crowell et al. (1967) reported that Eurasian watermilfoil
(Myriophyllum spicatura L.) xras the dominant aquatic macrophyte in
Currituck Sound by 1967. The invasion of the sound by Eurasian
watermilfoil brought complaints from local residents. This aquatic
macrophyte hampered recreational activities and formed undesirable
floating mats of decaying plants aligned in unsightly stinking windrox-^s.
Some residents also felt that there was a decline in use of the sound
by x^aterfox'7l. A management options study for Eurasian x^atermilfoil has
recently been completed under a program funded by Sea Grant College of
the University of North Carolina and the U. S. Department of Commerce.
This research was a part of that study.
None of the previous studies included an investigation of phyto-
plankton. Sincock (1965) mentioned aufv/uchs on submersed aqxiatic
macrophytes x/hich were composed of Nostoc spongiforme C. A. Agardh,
Rívularia globiceps G. S. West, Oscillatoria lemmermanni Lemmermann
Cosmarium sp., Oedogoniinn sp., Synedra pulchella O'Meara, Cocconeis
placentula Ehrenberg, Chroococcus limneticus Lemmenaanni, Gomphosphaerla
aponina Kutzlng, Merismopedia sp., Eunotia sp., Scenedesmus quadricauda
(Turp.) Brebisson, Pediastrum tetras (Ehrenberg) Ralfs, Staurastrum sp.,
Spirullna sp., and Achnanthes sp. A report by liíhitney et al. (1970)
stated that 19 plankton samples were analyzed but they did not publish
the results. They also acknowledged the lack of plankton population
data for Currituck Sound.
Phytoplankton investigations along the North Carolina coast
include studies on the Chowan River (Witherspoon, 1979) , on Gales Creek
(Campbell, 1973), on the Pamlico River Estuary (Robbie, 1971; Davis,
Brinson, and Burke, 1973; Kuenzler, Stanley, and Kcenings, 1979), in
shallow estuaries near Beaufort, North Carolina (Thayer, 1971), and on
the Neuse River Estuary (Robbie and Smith, 1975).
The purpose of this research was to study the seasonal variation
in species composition, numbers, and biomass of phytoplankton in the
Currituck Sound from November, 1977 to October, 1978. The Currituck
Sound is a large, shallow, fresh to oligohaline system which is unique
in the North Carolina estuarine system. As indicated above, nothing was
knoim about the planktonic comm\anities of the sound prior to the present
study. Seasonal variation of these communities are compared with fresh
to oligohaline segments of other North Carolina estuaries.
Study Area
The Currituck Sound is the northernmost sound along the North
5
Carolina coast (Flg.l). It extends 56.0 km southward from the
Virginia state line to the Albemarle Sound and averages about 8.0 km
in width. Average depth is 1.5 m (Kearson, 1973). It is separated
from the Atlantic Ocean by a barrier spit island which varies in width
from 0.4 to 1,6 km. Early records list four ocean inlets to the sound
and note that the last inlet closed in 1828 (Sincock, 1965). Presently,
the Currituck Sound exchanges water with the Albemarle Sound via Coinjock
Bay, the intercoastal waterway, and North River, as well as via its
southern terminus which is contiguous with the northeastern reach of the
Albemarle Sound (Carey, 1979). Water sources are from North Landing
River, Back Bay, marsh drainage and numerous farm drainage ditches.
Extensive marshes composed of cattail, three-square, spikerushes,
marshmallow, and smartweeds dominate the northern sound. Marshes in
the southern sound are composed of needlerush, big cordgrass, sawgrass,
and cattail and are not nearly as extensive as in the northern sound
(Sincock, 1965). Marsh islands in the middle reach act as barriers to
water circulation. There is no significant watershed for Currituck
Sound. It is contiguous with the northeastern reach of Albemarle Sound
with a wind driven exchange of waters. Submersed macrophyte biomass is
also higher in the northern sound than the southern area. The water
level is affected more by wind than by lunar tides. Sincock (1965)
reported fluctuations of no more than 1.3 m in the water level due to
wind tides. Carey (1979) observed current flows greater than 1 m per
second with northerly winds emptying the sound and southerly winds
filling it, Carey monitored changes in water depth from 14 July 1978

to 11 August 1978 and found 0.75 cm per hour the greatest rate of change
in depth.
MATERIALS AND METHODS
Field Methods
Hydrographic data and water samples were collected monthly from
November, 1977 through August, 1978 from 13 stations in Currituck Sound
(Fig. 2). On 23 September, 1978 a study was made of Coinjock Bay to
delimit the extent of a bloom observed on this date and to attempt to
determine the causal factors. On 8 October, 1978 a survey was conducted
of transect L to determine the variability of the phytoplanktonic
communities from shore to shore. Twelve stations were sampled in each
study. Measurements of temperature, salinity, and conductivity were
with a YSI Model 33-S-C-T meter and dissolved oxygen with a YSI oxygen
meter. Transparency was determined with a Secchi disk. Water was
tested for pH with short range alkacid test ribbons (0.5 pH unit
increment). Wind speed and direction for the sound were estimated.
Weather data were obtained from the National Weather Service for the
Norfolk, Virginia Station.
Filtered and xmfiltered aliquots of water were stored in the dark
on ice, frozen at the end of hydrographic runs and later analyzed.
Phytoplankton samples were collected 0.5 m below the surface,
fixed with a modified Lugol’s solution containing 10.0 g of iodine,
21.85 g of sodium acetate, 20.0 g of potassium iodide, and 200.0 ml of
distilled water. Substitution of the sodium acetate for acetic acid
better preserves coccolithophores (Hobbie, 1971). However, Campbell
(1973) stated that Lugol’s solution caused distortion of unarmoured
dinoflagellate cells and recommended centrifugation of live material.

Laboratory Analyses
Kjeldahl-N was determined by mercuric sulfate digestion (APHA, 1975)
and analyzed with an ammonium electrode (APHA, 1975). Nitrate-N was
determined by the UV spectrophotometric method (APHA, 1975). The
azo-spectrophotometric method (EPA, 1976) was used for the analysis of
nitrite-N. Ammonium-N was analyzed by the indolphenol method (Scheiner,
1976). Particulate-N was estimated by subtracting the dissolved
Kjeldahl-N from the total Kjeldahl-N. Phosphorus analyses were by con-
version to orthophosphate by persulfate digestion and molybdate spectro-
photometric analysis (EPA, 1976). Particulate-P was calculated as
total phosphorus minus dissolved phosphorus.
Phytoplankton density and biomass were determined by the Utermhhl
3
technique as m^odified by Lund et al. (1958). Fifty cm of the water
sample was allowed to settle in a sedimentation type counting chamber
for 24 hours. Random fields were then counted on a Wild M40 inverted
microscope at a magnification of 400X until at least 100 Individuals
of the most abundant species were counted. The count for each species
was converted to numbers per liter by considering the amount of the
sample settled, the area of the counting chamber, and the area of the
chamber counted. The counts of numbers per liter were converted to
volume per liter by multiplying by the volume of the species counted.
Species volume was obtained by determining the average cell dimensions
for each species and approximating the cell shape to the closest geometric
solid configuration. Volume per liter v/as converted to biomass by assuming
a specific gravity of unity. A sample calculation is given in Appendix E.
Variability of the counting procedure was detennined by taking 10
samples from a pail and counting the 12 most abundant species in each
50 cm^ sample. The coefficient of variation of 25.6% determined was
very close to that of Robbie (1971) for the Pamlico River Estuary and
to Willen (1976) for Lake Hjalmaren, Sxjeden. The coefficient of variation
for the error of the method indicated that there was adequate counting
precision for estimating the population biomass as compared with other
sources of potential error. These sources include the lack of a
uniform sample, uneven or incomplete sedimentation, determination of cell
volvimes and each researchers conversion of cell shapes to geometric
solid configurations. For example, most researchers interpreted the
diatom Navícula to a right circular cylinder. In this research, the
shape of this species was adjusted to two right circular cones. Since
the accuracy of counting varies inversely with the square root of the
number counted, doubling the number of organisms counted would have very
little effect on counting accuracy.
References used in identification included Campbell (1973), Cleve-
Euler (1951), Patrick (1966), Pestalozzi (1965), Prescott (1951),
Prescott(1970), Vinyard (1975), and Whitford and Schumacher (1973).
RESULTS AITD DISCUSSION
Areal and Temporal Variations in Biomass
and Density of Phytoplankton
Annual Survey The yearly cycle of biomass and numbers of phyto-
plankton is given in Figure 3. Monthly variations in biomass for the
13 stations are given in Figures 4-13. These numbers are averages of
samples from all the stations. Due to bad weather and an occasional
loss of sample, the number of samples are not the same on every date.
There were three periods of high biomass with late vrinter, mid
spring, and mid summer peaks. Phytoplankton density had an entirely
different pattern. Number peaks occurred in late fall, early spring,
late spring, and late summer. Biomass peaks represent moderate
numbers of medium sized organisms; whereas, the number peaks represent
large numbers of small forms (eg. small blue-green algae xíith volumes
of only a few p^).
The late winter biomass peak occurred in February, 1978 and was
composed of Zygnematales, Nostocales, Chroococcales, Centrales, and
Pennales (Figs. 14-16). Species of Cosmarium, Staurastrum, Anabaena,
Coelosphaerium, Aphanocapsa, and benthic and epiphytic diatoms such as
Navícula and Cocconeis had high biomass. Slightly higher cyanophyte
biomass occurred in the southern soxmd area for this period (Fig. 7).
Since many of the cyanophytes were benthic or tychoplanktonic species,
their presence could be explained by increased wind activity and
changed direction in February. Winds were estimated at 12 mph from
southwestern and westerly directions. Data from the National Weather
Service listed winds from the southwest with an average speed of 12.1 mph

and reaching a maicimum of 25 mph on the date of sample collection. Winds
were reported at 17 to 20 mph maximum for the 2 day period proceeding
collection day. Carey (1979) noted that southerly winds fill the sound.
Therefore, the cyanophytes may have entered the vrater column by stirring
of bottom sediments, increased current flow due to wind activity, and by
inflxix of water from the Albemarle Sound, North Landing River, and the
numerous marsh areas within the sound.
Secchi disk readings reached a minimum in February. This could be
attributed to increased phytoplankton biomass but more probably was due
to increased suspended sediments. Compensation point is the depth at
which plankton photosynthesis balances respiration. Normally this is
considered to occur at a depth where the light intensity (Z) is reduced
to approximately 1% of that at the surface (Campbell, 1973). The monthly
mean depths of 1% surface radiation (Zj^^ = 2.5 x Secchi disk depth) in the
Currituck are given in Figure 17. The factor of 2.5 was derived from
analysis of data taken in the Back Baj^-Currituck Sound studies (Sincock,
1965) in which Secchi depths were compared with submarine photom.eter
studies. Fluctuation of the average depth for 1% incident light during
the study period was directly related to periods of increased wind
activity as in February. Epiphytic species such as Cocconeis, Amphora,
and Stigeoclonium were found in greater numbers during periods of
increased wind activity as were benthic forms such as Navicula. Water
temperature averaged 3.9°C in February. Although this temperature was
higher than in January, it was probably not great enough to cause a
significant increase in phytoplankton biomass. Ortho phosphate and

total phosphorus increased during February along with total Kjeldahl-N,
amnonia-N, and nitrate-N. However, the N:P ratio remained high (38:1)
and greater than the accepted 10:1 requirement for optimal growth of
freshwater phytoplankton. Uitherspoon (1979) also noted a February
increase in biomass in the middle reach of the Chowan River at the
Colerain, North Carolina station which he attributed to longer residence
tine and slower moving waters.
The maximum biomass peak of 12.6 mg’l”^ occurred in May, 1978
(Fig. 10) (Table 1). Bloom (maximum biomass peaks for study period) species
consisted of Coelosphaerium, Aphanocapsa, and Merismopedia in the northern
sound. Species of Euglena, Trachelomonas, Lepocinclis, and Gymnodiniura
were dominant in the middle reach of the sound. In the southern portion,
various dinoflagellates along with diatoms such as Surirella and Melosira
dominated the plankton. On the collection date in May, winds were
estimated from the northeast at 17 to 23 mph. Data from the Norfolk
weather station slists winds from the north at 10.8 mph with gusts of 15
mph. For two days prior to collection date VTinds were from the north at
17 mph. Wind speed and direction coupled with run off was possibly
responsible for the blue-green biomass increase in the northern sound.
Numerous farm drainage ditches and marshes empty into the northern sound.
Spring rains possibly flushed species of blue-greens and euglenophytes
from these habitats into the sound. Also in May, temperature of the
water reached 23°C.
Blue-green algae contain gas vacuoles that tend to accumulate gas
wrLthin them as temperatures rise. These benthic and tychoplanktonic species
could very well have become buoyant as a result of gas accumulation in

these vacuoles and entered the water colinnn by flotation or by wind

sinking rates aiad allows greater chance of nutrient uptake, thereby
allowing these species to outcompete other species for available
nutrients. The presence of phycobilin accessory pigments enable them to
utilize a variety of light wavelengths by absorption through a variety of
pigment systems. Thus once incorporated into the plankton community by
winds, runoff, and increase in gases in the vacuoles, the cyanophytes
were able to outcompete other algal species for the necessary nutrients
and light.
Sincock (1965) noted that northeastern winds had the greatest fetch
on the sound and that turbidity was greater when winds were from this
direction. Data from the present study showed slight improvement in
compensation depth for May. More milfoil beds existed in the northern
sound and probably dampened the effect of the xíind in this area. The
appearance of benthic and epiphytic diatoms in the southern sound xías
probably due to suspension of bottom sediments, influx from marsh areas
and the Albemarle Sound, and separation from substrates induced by the
wind. During May, nltrite-N and ammonia-N reached their lowest
concentration (Table 1). However, nitrate-N was increasing. Nitrogen;?
ratios were within a 13:1 range throughout the sound. Therefore, a
combination of more favorable N:P ratios, increased water temperature,
and wind conditions probably led to the May biomass peak.
The mid summer biomass peak occurred in July with members of the
32
Volvocales such as Chlanydomonas, Pandorlna, and Eudorina along with
species of dinoflagellates such as Ceratium hirundinella and Gymnodinium
dominating the bloom. Greater biomass occurred in the southern portion
of the sound during July (Fig. 13). Larger species of phytoplankton
such as Ceratium hirundinella, which were present almost entirely in the
southern sound, were responsible for the greater biomass there. Nitrate-
N reached its minimum concentration in June, 1978 prior to the July
increase in phytoplankton biomass. The minimum levels for total-P and
orthc-P were recorded in July, 1978 at the time of this phytoplankton
increase.
In July, \7inds were calm, water temperature ranged from 28 to 29°C,
compensation depth was greatly improved and salinity averaged 0.2°/gQ.
Greater numbers of Ceratium hirundinella and Gymnodinium spp. present in
July could have resulted from a lack of competition. Blue-green biomass
was at its minimum in July. The lack of wind to resuspend these blue-
greens from bottom sediments and marsh areas could lead to increased
numbers of dinoflagellates by the lack of competition for nutrients.
It is also possible that blue-greens secrete substances that inhibit
dinoflagellates and other algal species. If so, a decrease in blue-green
algal populations could be associated with the increase in dinoflagellate
population.
Q
Phytoplankton density peaked in August, 1978 at 1.26 X 10 organisms
per liter. Desmids and blue-green algae were dominant throughout the
sound. Compensation depth reached its maximum in August (Fig. 17) as
did nitrate-N (Table 1). Particulate-P was at a minimum in August. Winds
33
were calm at this time. The density peak for June represents
Volvocales, Chlorococcales, Chroococcales and Pennales. The April
increase was composed of members of the Volvocales and Centrales. A
steady increase in water temperature and decrease in turbidity and wind
during these periods could result in increased density.
Special Studies; Coin.jock Bay and Transect L A study of Coinjock
Bay ( Fig. 18) in September, 1978 and transect L in October, 1978
revealed blooms of desmids and blue-greens with a noticeable increase
in diatoms in the October study as compared to September. The number
of phytoplankton in Coinjock Bay was 8.1 X 10^ organisms/ liter and biomass
was 10.8 mg»l Both numbers and biomass were higher at stations one,
three,four, and five. Nitrite-N, Kjeldahl-IT, and total-P were higher
at these stations than in the other areas sampled in Coinjock Bay.
Although winds were estimated at 23-25 mph from the northeast, turbidity;
was low. Norfolk w’ind data for this sampling period was 18.7 mph from
O
the east Trlth gusts up to 23 mph. Numbers V7ere 1.99 X 10° organisms/liter
and biomass 12.9 mg*l~^ in the transect L study. Sampling sites with
higher biomass were stations one, five, six, and seven. Kjeldahl-N and
total-P were also higher at these stationr.. However, densities and
biomass x^ere fairly uniform across the sound. Both desmids and blue-
greens reached peaks during these two studies. Since desmid density
increased from spring through fall, they were probably able to adapt to
the shallow waters of the sound and reproduce. The pH of 6.8 for the
sound posed no problem to desmid adjustment. Prescott (1968) stated
that filtrates from Oscillatoria and other blue-green algae increased
cell division rates of Cosmarium. If so, once desmids became part of
34
THE SAfPLING SITES
the plankton, population growth was stimulated by cyanophytes already
present. Decreases in densities of other algal species during these two
study periods could be due to competition with blue-greens and desmids
for available nutrients and light. Increased reproduction rates
coupled with long residence times could account for the increased
numbers during the September and October studies.
Origins of Phytoplankton
in the Water Column
The presence of benthic, tychoplanktonic (organisms which live
within the littoral zone but are not epiphytic (Prescott, 1977)), and
epiphytic species throughout the study period indicated the influence
of wind action in this shallow estuary. With increased wind velocity
and duration, the numbers of benthic, tychoplanktonic, and epiphytic
species became more numberous in water samples often increasing ten fold.
During the 10 month study, tychoplanktonic species totaled 75% of the
population, benthic species 2%, and epiphytic species 1% (Table 2).
Influ:<es of salt water either by storm ovemíash or by way of the
Albemarle Sound brought euryhaline species such as Calycomonas,
Skeletonema, Katodinium, and Amphiphora into the sound. These phyto-
plankton species had short, temporary residence times and were not con-
sidered part of the endemic phytoplankton population. Since these are
normally euryhaline species, it is unlikely that they would grow and
reproduce under the conditions of Currituck Sound. Also species of
desmi.ds found in the sound from spring through fall are not considered
to be native to the sound. Desmids are found in acid or soft-water
habitats such as sphagnum bogs or areas of shallow water which contain

organic acids. Optimuin pH range for most desmids is 5.4 5o 6.8 (Prescott,
1968). Therefore, it is probable that they entered the sound from the
surrounding tributaries and marsh areas during run off periods following
heavy rain. It is also possible that soma species of blue-greens and
euglenophytes entered the sound following heavy rains from the numerous
drainage ditches which empty into it.
The Naviculaceae were the best represented family of diatoms with
23 species identified. Many members of this family are benthic species
and vrere probably suspended into the plankton by stirring of the bottom
sediments and littoral regions by V7ind action. Species of Cocconeis,
an epiphytic diatom, were present in greater densities during periods
of increased wind velocity. Patrick (1966) stated that many species of
freshwater diatoms found in plankton were the same as those found in
the littoral zone and were derived from that source.
Difference between Populations in the
Northern and Southern Sound
Trends of blue-green algal dominance in the northern sound and a
greater diatom population in the southern sound were also noted during
the course of this study. The Mann-Hhitney test (Zar, 1974) confirmed at
the 0.05 significance level that blue-green and diatom densities were not
the same in the northern and southern regions of the sound.
Stepwise multiple regression analysis was performed between the
dependent variables, phytoplankton numbers and biomass, and the nutrients
and physical parameters measured (Tables 3-6). Although significant
relations are shown by multiple regression analysis, these are weak
and do not explain the differences in the populations betw^een the northern

and southern sound. Possible explanations for blue-green doininance in
the northern sound are greater numbers of input sources, shallower depth,
wind stress, slow currents, and the presence of numerous marsh islands
in the middle reach of the sound which constrict the flow of vrater into
the southern area. North Landing River, marshes, small creeks, and
numerous drainage ditches are fresh water input sources for the northern
sound. These are ideal habitats for blue-green algae. The northern
sound is more shallow than the southern sound thereby increasing wind
stress on the sediment in this region. Since many species of blue-green
algae were benthic or tychoplanktonic (Table 7), it is possible that
they were separated from their substrates during periods of increased
vrLnd activity. Likewise, runoff and warmer temperatures in the drainage
ditches and marshes could bring about flotation of blue-green algae and
their eventual entrance into the sound. Once incorporated into the
plankton, blue-greens vrere probably better equipped to compensate for
loss or sinking rates and were better competitors for the available
nutrients and light. Numbers and biomass were low in the winter months
and begax^ to increase in February’ and remained domrLnant through the fall
months.
Relationships between Phytoplankton and some
Chemical and Physical Parameters
Statistical analyses to test for correlations between phytoplankton
numbers and biomass and the physical and chemical parameters measured
during this study shov/ed weak negative but significant correlations at
the 0.05 significance level for total Kjeldahl-N, aramonia-N, total-P,
41
ortho-P, and Secchi disk transparency (Table 8). Stepwise multiple
regression analysis of biomass and numbers with the independent variables
were also performed (Table 9). All factors measured explained 21.3% of
the variation in phytoplankton numbers. A total of 11.3% of variation
in biomass was explained. Kuenzler e^ al. (1979) foiind that factors
significantly (P_^0.05) related to chi ^ were particulate-N, surplus-P
(accumulated phosphorus, not being used in metabolism or in structural
components), uptake rate of carbon, and phosphorus accumulation rate.
Salinity, temperature, inorganic nutrients and nitrogen uptake rates
were not correlated with any of the variables. They also found that
uptake rates and algal biomass indicators did not appear to be related
to the abundance of inorganic nutrients. They stated that since no
predictive or causal relationships resulted for the Pamlico River, such
studies might be futile. They further stated that for systems like the
Pamlico Ri.ver Estuary, algal biomass measured at one sampling period
might be the result of the Inorganic nutrient levels of the previous
sampling period thereby giving low correlation coefficients. It is
my opinion that the low correlations for the Currituck Sound reflect
this same possibility.

did not correspond to either the Pamlico River Estuary or the Chowan

Phytoplankton in Currituck Sound was distributed among six phyla
with Cyanophyta the most abundant. These six phyla included a total of
204 species in 67 genera and 14 orders (Appendix A). Cyanophytes
dominated the algal population throughout the 10 month study period
ranging between 43.6% to 83.9% of the total population. Chlorophyta
increased and remained at this higher level through fall. Cyanophyta
and Chlorophyta were codominant in the summer months with Cyanophyta
reaching a peak in fall. Chrysophyta Tjere dominant in spring and
?winter months with diatoms peaking in May. Euglenophyta composed less
than 2% of the population and reached a maximum in spring. Dino-
flagellates did not appear until spring and formed blooms in both spring
and summer (0.67 to 0.69 mg*!"^). Cryptophyta xrere present in the
sound at all times but composed less than 1% of the population.
The dominant cyanophytes vjere Merismopedia elegans, M. tenuissima,
Aphanocapsa, and Anabaena. Dominant Chlorophyta were Pandorina,
Crucigenia, and Scenedasmus, xrf.th desmlds such as Cosmarium, Staurastrum,
and Closterium becoming the most dominant green algae in late spring
through fall months. Dinoflagellates such as Ceratium hirundinella and
Gymnodinium fuscum reached highest biomass and numbers in îfay and July.
In the Choxian River (Witherspoon, 1979), biomass maxima occurred
in spring and fall, were high in summer and reached a minimum in vrLnter.
Witherspoon reported a blue-green bloom in spring as xjater temperature
began to rise. As for Currituck Sound, the blue-green increase was
thought to occur by flotation of these species as gas accumulates in gas
46
vacuoles T7ith increasing water temperatures. Peridinium was the most
important species throughout the Chox^an River during late summer and
early fall of 1975.
In the Pamlico River Estuary (Robbie, 1971; Kuenzler et al., 1979),
phytoplankton peaks were reported in late xd.nter, early spring, and
late summer. Campbell (1973) found similar patterns in Gales Creek.
Robbie (1975) reported algal blooms in the upper reaches of the Reuse
River in sximmer and fall and in the middle reaches in xiinter and spring.
In the Pamlico River Estuary and Reuse River Estuary, blue-greens
dominate upstream similar to dominance of blue-greens in the northern
portion of Currituck Sound. In Gales Creek (Campbell, 1973), flagellates
dominated upstream areas xíith diatoms dominating doxrastream. These
waters had decreasing nutrient gradients and increasing salinity
gradients doxaistream. Bloom, forming species are smaller forms of algae
than those reported for other systems. According to Robbie and Smith
(1975) chlorophyll cl values greater than 25yg*l~^ delimit blooms. On
this basis, blooms xære not observed in Currituck Sound since all
chlorophyll & data (Carey, unpublished) for the sound indicated levels
below this value. Low levels of phosphorus throughout the study period
could be the limiting factor for phytoplankton when other factors such
as turbidity and temperature are not limiting. In most of the other
studies reviexved here, nitrogen not phosphorus was reported as the
limiting factor to algal groxíth.
SUMMARY AÎÎD CONCLUSIONS
Unlike other estuaries along the North Carolina coastline, the
Currituck Sound is a shallox<r bar-built estuary with no direct opening
to the sea. Shalloímess of the sound results in turbulent currents
generated by W3.nd tides that greatly influence the circulation. This
creates conditions for rapid interchange of nutrients and organisms
between the water column and surficial sediments.
Cyanophyta were the dominant algae in Currituck Sound, not dino-
flagellates and diatoms that are normally associated with the Pamlico
River and other estuaries of the Southeast. Although phytoplankton
numbers and biomass are similar to those reported for other systems,
phytoplankton periodicity was different. Blue-greens dominated the
upper regions of the Pamlico River, Neuse River, and Chowan River in
summer months; vzhereas, blue-greens were codominant with greens in
Currituck Sound during the summer.
Blue-green dominance is explained better by examination of species
torpes and habitats than by water chemistry. A large percentage of
cyanophytas were benthic or tychoplanktonic species. Once they became
separated from their substrate and entered the water column, they were
capable of withstanding sinking losses and were more successful
competitors for the available nutrients and light.
Also unlike other estuaries along the North Carolina Coast,
phytoplankton abundance in Currituck Sound appears to be phosphorus
limited. That is, the nitrogen:phosphorus ratios v/ere alxiays higher
than the 10:1 accepted optimum ratio for freshwater plankton. Only on
one occassion did this ratio fall within the bounds of the accepted pro-
portions. In Hay, 1978, phytoplankton biomass reached its peak when the
N;P ratio was within a 13:1 range for the entire sound.
In conclusion, physical processes dominate over biological and
chemical processes in controlling phytoplankton variability in the water
column. Wind mixing is of particular importance and low phosphorus levels
may prevent dense blooms of blue-green algae.
