Organic Chemicals In Sediments From The Lower Chesapeake Bay, R. J. Huggett, P. O. Defur Jan 1987

Organic Chemicals In Sediments From The Lower Chesapeake Bay, R. J. Huggett, P. O. Defur

VIMS Books and Book Chapters

Many of the toxic organic chemicals affecting the marine environment are hydrophobic and associate with sediments. Sediments can accumulate the substances over long intervals and store them after the original source of the toxic material has been eliminated. Contaminated sediments can provide small but damaging amounts of the to.xicant to the overlying water for decades. For example, more than 10 years after the discovery of Kepone in the James River, Virginia, much of the James' fisheries ·is still closed because Kepone levels are above federal action levels.

Abundance Of Virginia Shellfish And Finfish, Herb Austin

VIMS Books and Book Chapters

Water temperature, which has been measured from the pier at the Virginia Institute of Marine Science (VIMS) since 1946, has shown a steady upward trend since 1975-1976. This trend has been most dramatic during the fall-winter period, with October and November of 1984 and 1985 being two of the warmest periods in the 30-year record. The fall of 1985 was the warmest in 30 years. Winter (January-March) temperatures have also shown a steady rise since the record cold January-February of 1977-1978.

Polynuclear Hydrocarbons In Sediments And Clams In The Vicinity Of A Refinery Outfall, P. O. Defur, M. E. Bender, C. W. Su, Et Al Jan 1987

Polynuclear Hydrocarbons In Sediments And Clams In The Vicinity Of A Refinery Outfall, P. O. Defur, M. E. Bender, C. W. Su, Et Al

Reports

The objectives of this study were: 1) to determine whether certain organic substances (polynuclear aromatic hydrocarbons) present in a refinery process water are found in adjacent sediments and bivalves; and 2) to determine the concentrations of the compounds detected.


Oyster Spatfall In Virginia Rivers: 1986 Annual Summary, James Whitcomb Jan 1987

Oyster Spatfall In Virginia Rivers: 1986 Annual Summary, James Whitcomb

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells is counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.
