Estuarine Response To Nutrient Enrichment, A Counterpart Of Eutrophication : An Annotated Bibliography, K. L. Webb, D. M. Hayward, J. M. Baker, B. Murray

Reports

This work is a result of our efforts to compile the literature related to the results of nutrient enrichment of estuaries. It consists of two related publications, a bibliography and an annotated bibliography; both works are accompanied by an index which applies to either bibliography. An attempt has been made to include some key papers related to various processes, eg. nutrient uptake by phytoplankton, which influence or participate in the response process.

An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz

Reports

A preliminary survey of summer plankton in ·waters surrounding the C. P. Crane generating station in Bengies, Maryland, revealed several possible effects of plant operation. These perturbations were separated into apparent small-scale and large-scale effects:

Small-scale effects were limited to the immediate discharge region of Saltpeter Creek and included (1) occasional elevation of temperatures at the surface (in August) to above the lethal limit for most zooplankton and sufficiently high to inhibit photosynthesis, (2) a decrease in chlorophyll-a, seen in July and August, (3) a sharp decrease in productivity, also in July and August, and (4) absence of a common …

An Analysis Of Phytoplankton, Microzooplankton And Mesozooplankton Populations In The Vicinity Of The C. P. Crane Generating Station During The Spring Months Of 1979, George C. Grant, Stephen P. Berkowitz

Reports

Sampling of spring 1979 plankton populations at the C.P. Crane site was conducted at 15 stations during six sampling periods for phytoplankton, at 5 stations monthly from March to June for microzooplankton and monthly at 14 stations for mesozooplankton. Ancillary physical data were collected at all the above stations, while nutrients were measured twice in April.

Community Structure Of Fishes On The Continental Slope And Rise Off The Middle Atlantic Coast Of The United States, John A. Musick

Reports

Otter trawl cruises were conducted off the middle Atlantic coast of the U. S. from 1971 to 1975. More than 50,000 specimens of demersal fishes were captured during this program at depths of 75 m to 3000 m. Species assemblages were distributed along a coenocline with bathymetric areas of rapid faunal change (anantoclines) and of more gradual faunal change (aganoclines). Between 75 and 3000 m anantoclines were found at 150 to 200 m, 400 to 600 m, 900 to 1000 m, 1350 to 1500 m, and 1900 to 2100 m. Species diversity (Hl) increased between the continental shelf and slope, …

Lower Bay Zooplankton Monitoring Program : An Introduction To The Program And Results Of The Initial Survey Of March 1978, George C. Grant, John E. Olney

Reports

The zooplankton of Chesapeake Bay occurs as two definable, seasonal populations: a summer-fall community, peaking in August, and a winter-spring assemblage, peaking in February or March (Grant 1977; Jacobs 1978). A minimum of two surveys per year are therefore required for long-term assessment of these communities: March and August have been selected as sampling months. Adequate assessment of meroplankton, particularly fish eggs and larvae and the larvae of decapod crustaceans, requires sampling over the principal reproductive period of June through August (Goy 1976; Olney 1978). Surveys for these components only are to be conducted in June and July, in addition …
