Age Based Assessment In The Sea Scallop Placopecten Magellanicus: A Pilot Study - Final Report, Roger L. Mann, David Rudders, Sally Roman, Melissa Southworth, Kaitlyn R. Clark
Age Based Assessment In The Sea Scallop Placopecten Magellanicus: A Pilot Study - Final Report, Roger L. Mann, David Rudders, Sally Roman, Melissa Southworth, Kaitlyn R. Clark
Reports
If the current sea scallop fishery is well managed with a Catch At Size Analysis (CASA) length structured model, then why bother with an age based assessment? The success of the CASA based approach, in conjunction with management measures, is demonstrated by the development of the scallop fishery over the past two decades to its current status as the one of the most valuable fisheries on the Atlantic coast of the United States (NOAA, 2021). But, even the best length-based model can be improved by the addition of age data. An age-based model calibrates a length-based model, including a description …

Development Of A Tidal Wetland Inventory And Assessment For York River, Virginia Watershed, Center For Coastal Resources Management, Virginia Institute Of Marine Science
Reports
As part of the Chesapeake 2000 agreement, the Commonwealth of Virginia pledged to a wetland policy of no net-loss. Through conscientious resource protection and management, Virginia’s non-tidal and tidal wetland permit programs, administered by the Virginia Department of Environmental Quality (DEQ) and The Virginia Marine Resources Commission (VMRC) respectfully, are committed to reaching this goal. In order to assist these agencies in realizing no-net loss of wetlands, the availability of baseline data is essential in defining our existing resources and is the basis from which future status and trends can be evaluated along with the effectiveness of permitting and management …

Tidal Freshwater Ecosystems: Bibliography, Daniel J. Yozzo, David E. Smith, Marilyn L. Lewis
Reports
Tidal freshwater ecosystems represent an important transition zone between saline reaches of estuaries and non-tidal riverine environments. Tidal freshwater systems are distributed worldwide, but have been intensively studied in only a few geographic regions, such as the U.S. east coast and western Europe. Typically, tidal freshwater systems are characterized by high physical stress due to sediment instability and tidal action, which results in low species diversity. However, a number of anadromous and resident fish species utilize tidal freshwater reaches of estuaries as a spawning and nursery area, including economically significant species such as striped bass, American shad, and Atlantic sturgeon. …

Benthic Study Of The Continental Slope Off Cape Hatteras, North Carolina, Robert J. Diaz, David P. Loshe, James A. Blake
Reports
Concern was raised by the NCESRP (1992) that since not much is known about the bottom communities around the Manteo 467 lease block, exploration activities could result in significant environmental disturbance. Therefore, the principal task of this study was to survey the sea floor of the Cape Hatteras continental slope in the vicinity of the Manteo 467 site prior tn any decision on permitting of exploratory drilling. The study objectives as listed in the scope of work are as follows:
1. Define the 'unusual benthic community' that exists offshore North Carolina which is at its peak in the vicinity of …

Experimental Colonization Of Crude Oil Contaminated Sediments By Benthos On The Middle Atlantic Continental Shelf, Donald Boesch, Eugene Burreson, Et Al
Experimental Colonization Of Crude Oil Contaminated Sediments By Benthos On The Middle Atlantic Continental Shelf, Donald Boesch, Eugene Burreson, Et Al
Reports
In August 1979 six arrays of defaunated sediment were deployed at each of three sites in the Middle Atlantic Outer Continental Shelf. Three arrays at each site had Prudhoe Bay crude oil mixed with the sediment. Because of technical difficulties recovery was limited to one control and one oiled array from two sites--one near the shelf break and one in a mid-shelf swale--after 10 months in situ. Moderate to severe sediment erosion occurred in boxes recovered from the mid-shelf. Chemical analyses indicated that between 50 and 90 percent of the added oil remained in the sediments after 10 months and …

The Consequences Of Nutrient Enrichment In Estuaries, Bruce J. Neilson
Reports
A "paper study" was conducted to determine the consequences of nutrient enrichment in an estuary. First, a classification scheme was developed to assign- a "Level of Nutrient Enrichment" to a water body based on concentrations of Total Phosphorus and Total Nitrogen. The impacts of nutrient enrichment on the various uses of estuaries there were described and assessed. Finally, "safe" nutrient levels for Chesapeake Bay and its tributaries were recommended.

Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo
Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo
Reports
Contamination of the James River in Virgin ia with the pesticide Kepone has resulted in its accumulation in the tissues of the fauna inhabiting the river. Most of the Kepone available to the biota in the river is associated with sediment s (Schneider and Dawson, 1978) and Haven and Morales-Alamo (1979) have shown that oysters and other bivalve molluscs accumulate Kepone in their tissues when exposed to the pesticide associated with sediments in suspension. It is of interest to compare the quantities of Kepone bound in James River sediments with the quantities bound in the molluscan fauna of the river.

Middle Atlantic Outer Continental Shelf Environmental Studies Volume 1: Executive Summary, E. M. Burreson, H. J. Knebel
Reports
Increasing demand for petroleum and natural gas in the United States has led to a need for development of reliable new domestic sources. The Outer Continental Shelf of the United States holds great interest among the oil companies for possible exploration and development of oil and gas resources to meet this need. This interest was demonstrated for the Middle Atlantic Outer Continental Shelf in the oil companies' response to the lease sale conducted in August 1976. Of the 154 tracts comprising 876,750 acres offered for lease in August 1975 for exploratory drilling in the Baltimore Canyon Trough (Figure 1), oil …

Water Quality Model Of York River, Virginia, Paul V. Hyer
Water Quality Model Of York River, Virginia, Paul V. Hyer
Reports
A ten-component time·-dependent Phytoplankton Ecosystem model was calibrated and verified for the York Estuary. Since the York is both wide and deep and is characterized by low dissolved oxygen levels in the deeper layer, this model has two layers and three compartments laterally per layer. The calibrated and verified model is suitable for use in studying water quality in the York, such as the.development of waste load allocations.
