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, …

Temporal And Spatial Variations Of The Chesapeake Bay Plume, Evon P. Ruzecki

VIMS Books and Book Chapters

Historical records and data obtained during the Superflux experiments are used to describe the temporal and spatial variations of the effluent waters of Chesapeake Bay. The alongshore extent of the plume resulting from variations of fresh water discharge into the Bay and the effects of wind are illustrated. Variations of the cross-sectional configuration of the plume over portions of a tidal cycle and results of a rapid-underway water sampling system are discussed.

Chesapeake Bay Plume Dynamics From Landsat, John C. Munday Jr., Michael S. Fedosh

VIMS Books and Book Chapters

Examination of 81 dates of Landsat images with enhancement and density slicing has shown that the Chesapeake Bay plume usually frequents the Virginia coast south of the Bay mouth. Southwestern (compared to northern) winds spread the plume easterly over a large area. Ebb tide images (compared to flood tide images) show a more dispersed plume. Flooding waters produce high turbidity levels over the shallow northern portion of the Bay mouth.

Bacterial Biomass And Heterotrophic Potential In The Waters Of The Chesapeake Bay Plume And Contiguous Continental Shelf, Howard I. Kator, Paul L. Zubkoff

VIMS Books and Book Chapters

Bacterial populations in Chesapeake Bay and contiguous shelf waters are significant to such essential processes as mineralization, nutrient recycling, degradation of pollutants and biomass production. However, our understanding of such dynamic relationships of physical and chemical factors to bacterial biomass and activities in Chesapeake Bay plume waters is limited. The availability of synoptic hydrographic (and remotely sensed physical-chemical) data obtained simultaneously with measurement of of microbial biomass and activity presented an opportunity to examine such relationships.

Study To Investigate Source And Transport Route Of Marine Organisms (Hydroids And Bryozoans) In Hampton Roads And Current Velocity Profiles Of The Pier 12 Area, Naval Station, Norfolk, Virginia, Robert J. Diaz, Evon P. Ruzecki

Reports

Entrainment of the hydroid (Sertularia argentea) and the fleshly bryozoan (Alcyonidium verrilli) in the sea suction of deep draft naval vessels (carriers) in the area of the Norfolk Naval station has been a recurring problem since the early 60's. These fouling organisms (the term fouling is used in this report to indicate clogging of hull bottom intake grates and cooling system condenser tube sheets and not the growth of organisms on any part of the vessel) are winter species, growing only in the fall and winter and not the summer. Unfortunately they are also the most abundant and widely distributed …

Morphology Of Udonella Caligorum Johnston, 1835, And The Position Of Udonellidae In The Systematics Of Platyhelminths, A. V. Ivanov

Reports

The platyhelminth, Udonella, lives on parasitic copepod crustaceans and, according to the present system of classification belongs to monogenetic trematodes (Monogena) among which it is usually placed in the group Monopisthocotylea (Fuhrmann, 1928; Bychowsky, 1937; Dawes, 1946; Sproston, 1946). However, the morphology of Udonella has not yet been studied thoroughly by anyone, and a number of unusual features of the structure, ontogenesis and biology of this form cause doubts with regard to its belonging to the Monogena.

Ontogenesis And Phylogenetic Interrelationships Of Parasitic Flatworms, Boris E. Bychowsky

Reports

The purpose of this report is to establish relationship among individual groups of parasitic flatworms, namely, among monogenetic trematodes (Monogenea), digenetic trematodes (Digenea), tapeworms proper (Cestoda), and the so-called Cestodaria group (AMPHILINIDAE and GYROCGTYLIDAE). The attempt to establish the above-mentioned relationships is made to a variable degree for different groups. The main point of this report is the establishment of phylogenetic relationship in the Monogenea, not only for the entire group as a whole, but also for the individual families which are members of this group. We feel that another important point is our attempt at clarifying the phylogenetic position …

The Feeding Ecology And Trophic Role Of The Northern Pipefish, Syngnathus Fuscus, In A Lower Chesapeake Bay Seagrass Community, Clifford H. Ryer

Dissertations, Theses, and Masters Projects

The purpose of this study is to examine the feeding ecology and trophic role/importance of the northern pipefish, Syngnathus fuscus, in a lower Chesapeake Bay seagrass community.

The study incorporates; 1) examination of stomach contents in conjunction with prey abundance data, inorder to arrive at conclusions concerning the food preferences of S· fuscus, 2) determination of daily feeding periodicities and stomach evacuation parameters, thus allowing for the determination of a daily ration for S· fuscus, 3) examination of size relationships between S. fuscus and it's major prey species, 4) estimation of pipefish densities at the study site, and 5) examination …
