A Socio-Economic Environmental Baseline Summary For The South Atlantic Region Between Cape Hatteras, North Carolina And Cape Canaveral, Florida - Volume Iii: Chemical And Biological Oceanography, Virginia Institute Of Marine Science

Reports

The geographic area covered in this report extends from Cape Hatteras, North Carolina, on the north, to Cape Canaveral, Florida, to the south. Included within this area are portions of the coastal areas of South Carolina and Georgia. All or portions of thirty coastal counties are included within the study area.

From a chemical standpoint, the area is characterized by nutrient input from rivers, especially nitrogen, resulting in low phytoplankton production. Heavy detritus loads from adjacent salt marches keep the oxygen level in estuaries below saturation. These streams have little capacity to assimilate additional oxygen demand.

Zoogeographically, the area comprises …

A Survey Of Commercial Shellfish Around Pig Point In The Nansemond River, Dexter S. Haven, Paul C. Kendall

Reports

This is a report of work done by the Virginia Institute of Marine Science in accordance with an agreement with NUS Corporation, Pittsburg, Pennsylvania. The objective of this study was to determine on public bottoms the magnitude of the oyster and clam resource in the vicinity of the proposed refinery at Pig Point and along the proposed pipeline from Newport News to Pig Point. The area covered in this study was the width of the James and extended from just up-river of Craney Island to Candy Point. Included in this report is a review of production, MSX, and pollution in …

Survey Of Cultchless Spat Planted By The Vmrc In Nomini And Lower Machodoc Creek, Dexter S. Haven

Reports

As part of a major repletion activity by the VMRC, cultchless spat were planted in Lower Machodoc Creek and Nomini Creek in October and November 1973. The Virginia Institute of Marine Science surveyed these plantings on 10 and 11 December, 1973. The areas planted and surveyed are shown in figures 1 and 2.

In Lower Machodoc Creek, 5.35 acres were planted with 240.5 bushels of cultchless spat during October, 1973. Within this area, five sub-areas were seeded, each with about one million spat. In Nomini Creek there were two planting areas. The largest was located in Nomini Cut, and seven …

Oyster And Hard Clam Distribution In The Lower York River With Notes On Culture, Disease And Pollution, Dexter Haven, Paul Kendall

Reports

Outlined in this report are aspects of the distribution and. culture of clams and oysters of the lower York River. Included are two acetate overlays attached to u. S. Coast and Geodetic Survey Chart 492. The first shows locations and density of the hard clam Mercenaria mercenaria; the second shows the location of public oyster and clam grounds, oyster planting ground, and half-acre plots held by "riparian rights". Accompanying the latter chart is a complete list of the names and addresses of the holders of all "riparian rights" and lease holders (Appendix I). The area covered by this list is …

The Effect Of Sewage Effluents And Their Constituents Upon The Vegetative Growth Of Ulva Lactuca Linnaeus 1753 (Sea-Lettuce) : Progress Report, Frankin D. Ott

Reports

Ulva lactuca Linnaeus 1753, referred to in the vernacular as "Sea Lettuce" is a green, marlne alga often forming large, distromatic blades of considerable size. It usually begins its existence from a single celled, germinating zygote or germinating zoospore. During its early stages it is almost always attached to some object. As it increases in size, it may become detached either by its sheer bulk, or by the action of rough waters . Once it is detached, however, it can continue its growth, often at a very rapid rate, if the environmental conditions are satisfactory. Large pieces may become fragmented …

Lower York River Dissolved Oxygen Study, Robert A. Jordan

Reports

Past studies of the lowerr York River have shown that dissolved oxygen (D .O.) concentrations decline in the summer months, occasionally falling one mg/ 1 near the bottom in deep water (Brehmer,1970; Jordan,1973) . Due to this apparently natural phenomenon the Virginia water quality standards for D.O. in estuaries (4.0 mg/1 allowable minimum, 5 .0 mg/1 minimum daily average, U.S.. E.P.A,1971), are not met during this period . Therefore additional waste-water discharges into the lower York River will not initiate violation of the standards, but may exacerbate the existing situation by extending the area and the time period affected by …

A Preliminary Report To The Virginia Department Of Highways On Hard Clam (Mercenaria Mercenaria) Populations In The Vicinity Of The Hampton Roads Bridge-Tunnel (I-64) (Segment 268-135d), Dexter S. Haven, Paul Kendall, Reinaldo Morales-Alamo

Reports

1-664 will be constructed in Hampton Roads in an area where the hard clam Mercenaria mercenaria is fished commercially. Because of this c.lam's economic value and because Hampton Roads is the major producing region for this species, it is worthwhile that every precaution be taken during construction of I-664 to minimize the possibility of .damage to this resource. ·To achieve this objective, we are evaluating the possible impact of construction activities around I-64 and adjacent areas on populations of the hard clam. The aim is that if damage or potential damage. is noted around I-64, then construction techniques may be …

Fungi Associated With Decaying Spartina : Final Report, Frederick Y. Kazamak

Reports

Althfinal report, National Science Foundation grant GA-31899ough marine fungi have been studied since the mid 1800's, there have been relatively few physiological-ecological studies concerning the role of the fungi in the marine environment. Most studies have dealt with lignicolous or sediment-inhabiting fungi (see Johnson and Sparrow, 1961). After the importance of detritus in estuarine energy flow had been established (see Odum and de la Cruz, 1967 for references), there have been a number of papers dealing with the mycoflora of decomposing Spartina (see Gessner and Goos, 1973 a, b) and the mangrove (see Fell and Master, 1973; Newell, 1973). In …

Acute Effect Of Free Chlorine On Selected Estuarine Invertebrates And Vertebrates : Final Report, Morris H. Roberts, Robert J. Diaz

Reports

The objective of this project was to determine acute toxic effects of chlorine on selected estuarine organisms found adjacent to the projected outfall of a sewage treatment plant in the lower York River. The test species specified under contract were ovster (Crassostrea virginica) and clam (Mercenaria mercenaria) larvae, Acartia tonsa (a dominant copepod), and the fishes, menhaden (Brcvoortia tyranus), pipefish (Svngnathus fuscus), blennies (Hypsoplennius hentzi) and sheepshead minnow (Cyprinodon variegatus). The parameter of interest in the tests was mortality when the animals were exposed to a constant level of chlorine for a 48 or 96 hr period.

Inventory Of Surf Clams In Nearshore Waters From Cape Henlopen To The False Cape Area : Quarterly Progress Report, September 16, 1974 - December 15, 1974, Joseph G. Loesch

Reports

A survey of the surf clam@pisula solidissima) in the nearshore area along the Delmarva Peninsula and further offshore from Cape Henry to upper North Carolina was conducted from 4 October, 1974 through 15 October, 1974. The project is a joint undertaking by the National Marine Fisheries Service (NMF'S) and the Virginia Institute of Marine Science (VIMS). A total of 138 sites were sampled with a hydraulic tow dredge and, in addition, a benthic sample for juvenile clams were obtained at each site with a Smith-MacIntyre sampler.

Because of this clam 1s economic value and because Hampton Roads is the major producing region for this species, it is worthwhile that every prer:: aution be taken during construction of I-664 to minimize the possibility of damage to this resource.

To achieve this objective, this study was undertaken to evaluate the pwsible impact of I-64 and of construction activities around I-64 on adjacent populations of the hard clam. The objective of the study was that if damage or potential damage …
