Wetlands Evaluation And Management In Virginia, Eileen L. Shea, N. Bartlett Theberge

Reports

Complex biotic communities which have lately been recognized as being of vital importance to aquatic and upland ecosystems have evolved at Virginia's land-water interface. Most obvious are the beaches and vast intertidal stands of halophytic (salt-tolerant) plants on the periphery of the Atlantic Ocean, Chesapeake Bay and their subordinate estuaries. Less obvious, but no less important, are nonvegetated intertidal flats and coastal freshwater marshes. Inland swamps and freshwater marshes complete the inventory; though more limited in extent than their coastal analog. Complex biotic communities which have lately been recognized as being of vital importance to aquatic and upland ecosystems have …

Characterization Of The Demersal Fish Community Of A Deep-Sea Radioactive Dump Site (Results Of Cruise Epa-7801, R/V Advance Ii, 21-27 June 1978), John A. Musick, Kenneth J. Sulak

Reports

The present report describes the demersal fish fauna collected by otter trawl from RV Advance II on cruise EPA-7801 in the vicinity of a radioactive waste disposal site (R.D.S.) located at a depth of about 3900 m, approximately 200 miles due east of the Virginia coast (Figs. 1, 2). Because the sampling· effort at the R.D.S. was restricted by time and funding, the limited data base accrued from there was analyzed and compared with a much larger data set collected during previous deep-sea trawling studies using the same trawl gear.

Blue Crab Shedding Plants, W. A. Van Engel, Dale Ludi

Reports

Cool weather and two northeast storms, in April and May, are believed by Rappahannock River crab fishermen and shedders to have caused a three to four week delay in crabs reaching the early peeler stages of development. Fishermen are still setting crab pound nets (=peeler traps, fykes). Fishermen recall that prior to 12-15 years ago the first "run" of peeler crabs occurred on the full moon of late April or early May. Recently the "runs" have been later, but never as late as this year.

Report Of The National Blue Crab Industry Workshop: September 10-11, 1977 Charleston, South Carolina, Raymond J. Rhodes, W. A. Van Engel

Reports

The National Blue Crab Industry Workshop was held on September 10-11, 1977 at the South Carolina Marine Resources Center of the South Carolina Wildlife and Marine Resources Department in Charleston, South Carolina. The workshop was organized to address the blue crab industry's major problem areas and stimulate innovative thinking for improving productivity. The problems faced by the blue crab industry are not necessarily unique compared to other food industries; consequently, methodology to mitigate these problems will probably be transferred from other industries. Much of what was discussed in the technology corrnnittees has been faced by other industries, although recent food …

Final Technical Report For Nsf Grant #Oce 75-20241, Entitled Identification And Role Of The Ultraplankton Of The Lower Chesapeake Bay Region, Frank O. Perkins, Kenneth L. Webb

Reports

Numbers and species identities of the most dominant small (<15μm) photosynthetic Plankton were determined from samples of lower Chesapeake Bay water. The data is being compared to physical and chemical measurements of the Bay waters in an effort to determine conditions which encourage or inhibit growth of the organisms. Pure cultures of some of the more common species have been established and are being used to evaluate the roles of the organisms in terms of photosynthetic rates and utilization and excretion of nitrogen compounds.

Uptake Of Kepone By Oysters Exposed To Contaminated Sediments Mixed With Lignite, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Preliminary studies conducted by personnel of the Allied Chemical Corporation at Morristown, N. J. suggested that coa] would be used to adsorb Kepone from an aquatic substrate. .The possibility of using coal to bind Kepone contaminating the natural environment indicated further preliminary exploration of the matter.

The Virginia Institute of Marine Science undertook a laboratory study with oysters under contract with the Allied Chemical Corp. to explore that possibility. Lignite was mixd on a 1:10 dry-weight ratio with sediments contaminated with Kepone.

A Survey Of The Shellfish Resources Adjacent To Croaker Landing In The York River, Virginia, Dexter S. Haven, Paul C. Kendall

Reports

From 7 March 1978 through 14 March 1978, an area of the bottom in the York River around Croaker Landing was studied to define the existing shellfish resource. The study was conducted at the request of the Division of Parks of the Virginia Department of Conservation and Economic Development in conjunction with the construction of the York River State Park. Comparison of this study with a post-dredging assessment will provide a measure of the possible impact of dredging activities on the surrounding bottom.

Harmonic Analysis And Tidal Prediction By The Method Of Least Squares: A User's Manual, John D. Boon, Kevin P. Kiley

Reports

A common objective in the treatment of measured tides is the mathematical separation by harmonic analysis of certain periodic components which can be used to simulate the astronomical tide. Traditionally, astronomical or predicted tides have been represented by the sum of several such components, each one due to a particular aspect of the tide-producing forces. Once determined, the same set of parameters governing each periodic component may be used to predict the tide during any desired time period at a given location. These parameters are known as the tidal constants for that location. Although a number of different methods have …
