Mid‐Level Intrusions At The Continental Shelf Edge, Christopher S. Welch

VIMS Articles

Observations across the continental shelf offshore from New Jersey in late summer 1976 show an intrusion of saline water at the mid level of the water column across the shelf edge front, which appears in density only as an offshore thickening of the pycnocline. This internal density field produces horizontal pressure gradient forces within the pycnocline in the onshore direction. These forces, in the linearized equation of motion with a constant eddy viscosity, drive a circulation which resembles a double Ekman spiral for internal pressure vertical distributions which are thin with respect to the Ekman depth. For thick pressure distributions, …

Diclidophora Nezumiae Sp. N. (Monogenea: Diclidophoridae) And Its Ecological Relationships With The Macrourid Fish Nezumia Bairdii (Goode And Bean, 1877), Thomas A. Monroe, Ronald A. Campbell, David E. Zwerner

VIMS Articles

Diclidophora nezumiae sp. n. is described from the gills of the rat-tail fish Nezumia bairdii (Goode and Bean, 1877) taken from the environs of Hudson Submarine Canyon in the northwest Atlantic. The host-parasite relationships were studied in the host population. The new species is most similar to small species of Diclidophora having short bodies that taper to maximum width at the level of the first pair of clamps. It may be differentiated from other species by the following: clamps wider than long, noticeably decreasing in size posteriorly; lamellate extension of sclerite b does not fuse with sclerite c1; unsclerotized diaphragm; …

Organic Compounds In Surface Sediments And Oyster Tissues From The Chesapeake Bay, R. H. Bieri, P. O. Dufur, R. J. Huggett, W. Macintyre, P. Shou, C. L. Smith, C. W. Su

Reports

This report contains three parts. In Part I, the methodology to extract and analyze sediment and oyster tissue samples from the Chesapeake Bay is described in detail. Remaining problems are clearly identified. Part II contains the results and their discussion. Part III contains a number of appendices with detailed data. For those readers interested in still more detail, the complete bank of processed data is on computer tapes at this institute and at the Environmental Protection Agency-Chesapeake Bay Program office at Annapolis, Maryland. Also included in Part III we give the results of volatile halogenated organic compounds determined in water …

Notes On Msx Resistance Of Selected Virginia Oysters, J. D. Andrews

Reports

The purpose. of these summaries is to demonstrate that a high level of genetic resistance to MSX has been acquired in lab-bred oysters in Virginia waters. The brood stocks were selected from survivors of James River seed oysters that were 90% killed in the early 1960's on private beds in Mobjack Bay. Only data from the years 1976 to 1980 are given in this summary, although comparable data have been accumulated since 1964 when laboratory· breeding began.

Notes On Oyster Diseases In Virginia, J. D. Andrews

Reports

The weather continues to occur in extremes that interfere with growth and survival of oysters in the Chesapeake Bay. First there was a very wet year in 1979 (some 63-65 inches annual rainfall), much of which occurred in excessive amounts (some 15 inches) between late September and early November. Oysters in the upper James River seed-oyster area were killed by prolonged exposure to fresh or near-fresh waters in fall and winter of 1979-80.

The Present State Of Organic Xenobiotics In The Chesapeake Bay - A Synthesis Paper, R. J. Huggett, R. H. Bieri, P. O. Defur, W. G. Macintyre, P. Shou, C. L. Smith, C. W. Su

Reports

This manuscript discusses the results of the first two and one half years of a three-year study designed to determine the present state of xenobiotic compounds in the Chesapeake Bay. It shows that polynuclear aromatic hydrocarbons are the most frequently encountered compounds and are the most abundant. Concentrations are highest in the Northern Bay with several sources implicated. During this study an apparent dumping of the pesticide, DDT, occurred. Either the quantity disposed of was small enough or the assimulation capacity was large enough that no adverse effects were noted. The detection by us of 6-phenyldodecane in bottom sediments of …
