Legal Symposium On Wetlands: An Executive Summary, Roger D. Anderson, David Garten, Ted Smolen Nov 1974

Legal Symposium On Wetlands: An Executive Summary, Roger D. Anderson, David Garten, Ted Smolen

Reports

In 1969 the Virginia Institute of Marine Science published a report stating that although marshlands represented only one-half of one percent of the total area of the state, 95 percent of Virginia 's annual harvest of sport and commercial fisheries were dependent to some degree upon these valuable wetlands . The report went on to urge some form of public control over these vital areas in order to relieve some of the pressures created by dredging, filling, diking and bulkheading.

Recognizing the need to address this issue, the 1971 General Assembly passed House Joint Resolution Number 60, creating a Wetlands …

Function Of Marshes In Reducing Eutrophication Of Estuaries Of The Middle Atlantic Region, D. M. Axelrad, M. E. Bender, K. A. Moore Jan 1974

Function Of Marshes In Reducing Eutrophication Of Estuaries Of The Middle Atlantic Region, D. M. Axelrad, M. E. Bender, K. A. Moore

Reports

Annual nitrogen, phosphorus and carbon budgets for two Virginia salt marshes were determined by monthly measurements of water discharge and constituent concentrations over tidal cycles.

Considering all three forms of phosphorus measured (total, dissolved organic and orthophosphate) there was a net loss from the estuary to the marshes. The data reveal a loss of particulate μhosphorus of estuarine origin to marsh sediments and mineralization of this phosphorus in the marshes with subsequent export of dissolved inorganic and organic phosphorus back to the estuary.

Nitrogen flux data show a loss of nitrate and nitrite to the marshes. Particulate nitrogen is imported …


Virginia And The Outer Continental Shelf : Problems, Possibilities, And Posture, The Committee Jan 1974

Virginia And The Outer Continental Shelf : Problems, Possibilities, And Posture, The Committee

Reports

The Outer Continental Shelf Advisory Committee was \ established.by the Secretary of Commerce and Resources, Earl J. Shiflet, in July, 1974. This action was taken based upon the realization that the Atlantic Outer Continental Shelf (OCS) was a likely area for the development of offshore oil and gas resources, and that such development could have profound and far reaching impacts upon the Commonwealth. Such impacts could either be beneficial or detrimental or both, depending greatly upon the preparations made by the Commonwealth beforehand. Accordingly, Secretary Shiflet charged the OCS Advisory Committee to consider all facets of the situation, and to …


A Report On The Concentration, Distribution And Impact Of Certain Trace Metals From Sewage Treatment Plants On The Chesapeake Bay, Robert J. Huggett, O. P. Brickner, G. R. Helz, S. E. Sommmer Jan 1974

A Report On The Concentration, Distribution And Impact Of Certain Trace Metals From Sewage Treatment Plants On The Chesapeake Bay, Robert J. Huggett, O. P. Brickner, G. R. Helz, S. E. Sommmer

Reports

Population densities are ever increasing on the shores of the Chesapeake Bay and hence the flow of goods and services is being shifted to supply these people. This self perpetuating system demanismore and more of the surrounding envirorunent f or recreation, work and waste disposal. This is the case f or the Chesapeake and its sub- estuaries.

According to Brush (1974), of the total fresh water input into the Chesapeake Bay, between 1 and 2 percent is treated sewage. Toxic components on these waters may be of paramount importance in the Bay ecosystem and ma;y have disastrous effects on the …


Acute Effect Of Free Chlorine On Selected Estuarine Invertebrates And Vertebrates : Final Report, Morris H. Roberts, Robert J. Diaz Jan 1974

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.


Report On Water Quality Data Evaluation And Program Design Services For The James And York Rivers In Conjunction With The "208" Planning Program For The Tidewater Region Of Virginia, Michael E. Bender, C. S. Fang, Bruce J. Neilson Jan 1974

Report On Water Quality Data Evaluation And Program Design Services For The James And York Rivers In Conjunction With The "208" Planning Program For The Tidewater Region Of Virginia, Michael E. Bender, C. S. Fang, Bruce J. Neilson

Reports

The study area considered in this report includes the following: The James River from Fort Monroe to the mouth of the Chickahominy River (statute mile 45) including the small tributaries on the north shore but not the Chickahominy; the York River from its mouth to the confluence of the Mattaponi and Pamunkey at West Point (statute mile 33.5) including the small tributaries along the south shore; and the small drainage area adjacent to Chesapeake Bay lying between the York and James basins. The two rivers included in this basin are Poquoson River and Back River.

Ecological Survey, Upper James River, Surry Nuclear Power Station Site, August 1974, M. Bender, R. Jordan, M. Ho, M. Cavell

Reports

In May of 1969 field surveys to characterize selected biological communities in the Hog Island area of the James River were begun. The objective of these surveys has been to determine if significant changes occurred in the species composition or population levels of certain communities which could be related to the operation of the nuclear power generation station. Although during the period of study, methods and stations have been changed to adjust the study to changing regulations, its basic character has remained. Communities studied have included benthos, zoo- and phytoplankton and fouling organisms.

Final Report On Environmental Effects Of The Second Hampton Roads Bridge-Tunnel Construction To Virginia Department Of Highways : Effects On Benthic Communities, Donald F. Boesch, David H. Rackley

Reports

A sampling program was undertaken from July 1973 to June 1974, to assess the effects of construction of the second Hampton Roads Bridge-Tunnel on the benthic communities in the vicinity. Macrobenthic animals (defined as those retained by a 1.0 mm mesh sieve) were quantitatively sampled along three transects perpendicular to the new tunnel and in and around the fill "borrow areas" nearby on Willoughby Bank and Sewell's Point Spit. The effects of construction practices on the benthic communities·was assessed through interpretation of faunal composition, sediment characteristics, and bottom profiles.

A Program To Monitor The Environmental Effects Of Shipyard Expansion : A Final Report, Robert J. Diaz, M. E. Bender

Reports

Dredging and land reclamation are two of the potentially most damaging activities that man undertakes in estuarine areas. Hampton Roads, the world's largest natural harbor, is a multiple use port, being a major center for fishing and shellfishing, transportation, recreation and industrial sitings. Dredging which is a necessary perpetuation for some of these activities, could be directly or indirectly detrimental to others. It is in such a multiple use situation that environmental alterations, real or potential, must be carefully planned and closely monitored. Projects of the type underway can cause changes in circulation, water depth, turbidity, and patterns qf siltation, …
