Marine Ecosystem Research At The Weddell Sea Ice Edge: The Ameriez Program, Walker O. Smith Jr., Dl Garrison Nov 1990

Marine Ecosystem Research At The Weddell Sea Ice Edge: The Ameriez Program, Walker O. Smith Jr., Dl Garrison

VIMS Articles

The explorers and naturalists who first visited Antarctica were struck by the large numbers of whales, seals and seabirds in such a harsh environment (summarized in Everson, 1977). Scientific expeditions in the twentieth century confirmed these observations, and also established that an even greater abundance of many different trophic levels occurred at the ice edge. Hart (1942) noted that phytoplankton were more abundant near the ice edge mad suggested that there was a distinct ice-edge flora, and Marr (1962) noted that krill (Euphausia superba) were concentrated at the interface between pack ice and open water. Routh (1949) observed …

Ancient Channels Of The Susquehanna River Beneath Chesapeake Bay And The Delmarva Peninsula, Steven M. Colman, Jeffrey P. Halka, C. Hobbs, Robert B. Mixon, David S. Foster Sep 1990

Ancient Channels Of The Susquehanna River Beneath Chesapeake Bay And The Delmarva Peninsula, Steven M. Colman, Jeffrey P. Halka, C. Hobbs, Robert B. Mixon, David S. Foster

VIMS Articles

Three generations of the ancestral Susquehanna River system have been mapped beneath Chesapeake Bay and the southern Delmarva Peninsula. Closely spaced seismic reflection profiles in the bay and boreholes in the bay and on the southern Delmarva Peninsula allow detailed reconstruction of each paleochannel system. The channel systems were formed during glacial low sea-level stands, and each contains a channel-fill sequence that records the subsequent transgression. The trunk channels of each system are 2 to 4 km wide and are incised 30 to SO m into underlying strata; they have irregular longitudinal profiles and very low gradients within the Chesapeake …

Reports

The Virginia Institute of Marine Science, in cooperation with the Virginia Department of Conservation and Recreation, Division of Soil and Water Conservation, has identified as one of its major goals the systematic study of hydrodynamic processes that affect recreational, shoreline and benthic resources in the coastal zone of the Commonwealth. In pursuit of that goal, a long-term study of the wave climate in the Virginia portion of Chesapeake Bay was initiated in 1988 with support from the National Oceanographic and Atmospheric Administration through the Coastal Zone Management Program administered by the Virginia Council on the Environment (Grant Ho. HA88AA-D-CZ092). Past …

Geological And Benthic Evaluation Of Sand Resources In The Lower Chesapeake Bay, Report 2, Tail Of The Horseshoe : Final Report V.1, Carl C. Hobbs Iii, Linda C. Schaffner

Reports

This is the second of two reports concerning the resources of sand in the lower portions of Chesapeake Bay. The first, Geotechnical and Benthic Evaluation of Sand Resources in the Lower Chesapeake Bay (Kimball and others, 1989), presents a study of the resources in Thimble Shoal. The present work is a study of the area known as Tail of the Horseshoe which is just east of Thimble Shoal (Figure 1). The deposits of sand described in this report will be of most interest to the communities of Norfolk and Virginia Beach.

A Survey Of Compensatory Mitigation Within The Tidal Wetlands Of Virginia, Thomas A. Barnard, Pamela Mason Feb 1990

A Survey Of Compensatory Mitigation Within The Tidal Wetlands Of Virginia, Thomas A. Barnard, Pamela Mason

Reports

This study has as its primary purpose an examination of how compensatory mitigation has worked as a wetlands management tool to date in Virginia (i.e. how well theory has been put into practice). Our approach was to look at the overall use of compensation in coastal Virginia based on regulatory records and to examine as many existing created wetlands as possible within the tidal area of the state to determine how closely these projects have come, collectively, to fulfilling the compensatory goal of wetland replacement. Secondary objectives includes an examination of the literature regarding wetland compensation concept evaluation and to …

Acoustic Geology Of A Portion Of Virginia's Innermost Continental Shelf, Carl H. Hobbs Iii Jan 1990

Acoustic Geology Of A Portion Of Virginia's Innermost Continental Shelf, Carl H. Hobbs Iii

VIMS Books and Book Chapters

Side-scan sonography of the innermost continental shelf between Cape Henry and the Virginia-North Carolina border depicts a relatively typical inner shelf bottom generally characterized by medium density, meso-scale roughness. Subbottom acoustic protiles depict the stratigraphy as a Tertiary age basement separated from Quatenary-age deposits by a regional, angular(?) unconformity. Holocene-age sediments form a discontinuous layer above another unconformity. The area's topography appears to be a function of the presence of the modern sediments.


Heavy Mineral Concentrations In Sediments Of The Virginia Inner Continental Shelf, C. R. Berquist Jr., C. T. Fischler, L. J. Calliari, Et Al Jan 1990

Heavy Mineral Concentrations In Sediments Of The Virginia Inner Continental Shelf, C. R. Berquist Jr., C. T. Fischler, L. J. Calliari, Et Al

VIMS Books and Book Chapters

The Virginia Division of Mineral Resources and the Virginia Institute of Marine Science investigated the occurrence of heavy minerals in the offshore sediments of Virginia. We began the project because earlier reconnaissance studies reported high heavy-mineral concentrations from several samples collected off the Eastern Shore of Virginia. Our work confirms the previously reported mineral values and locates additional high concentrations up to 20 nautical miles offshore. Furthermore, we show that potentially economic mineral values are not restricted no surficial sediments, but also are found in the upper 15 to 20 feet of inner continental shelf sediments. Several core samples indicate …


The Dynamics Of Long-Term Mass Transport In Estuaries, John M. Hamrick Jan 1990

The Dynamics Of Long-Term Mass Transport In Estuaries, John M. Hamrick

VIMS Books and Book Chapters

The dynamics of long-term mass transport in estuaries having weakly nonlinear long wave dynamics are investigated. Low pass filtered long-term mass transport equations are derived for conditions of weak and strong vertical stratification. The dynamics of the residual mass transport velocity, or lowest order approximation to the Lagrangian residual velocity, are investigated by perturbation analyses of the hydrodynamics equations. For weak vertical stratification conditions, analytical results showing the influence of topography, the earth's rotation, and channel curvature on the distribution of the residual mass transport velocity field are presented. The calculation of the residual mass transport velocity field from field …

Population Dynamics Of Young-Of-The-Year Striped Bass, Morone Saxatilis, Populations, Based On Daily Otolith Increments, Lisa L. Kline

Dissertations, Theses, and Masters Projects

Validation of daily increment deposition in otoliths of juvenile striped bass up to 80 days of age was provided through sequential sacrifice of known age hatchery-reared fish in 1987 and 1989, and through tetracycline marking of otoliths of cage-cultured striped bass in 1989. Ages of fish between 80-110 days old were consistently underestimated by 1-3 growth increments. Known age juvenile striped bass were raised in the laboratory in 1989 under controlled environmental conditions. These experiments provided evidence of an endogenous circadian rhythm controlling daily increment deposition in juvenile striped bass otoliths. Juvenile striped bass were collected in the 4 Virginia …


Injection Efficiency Of Bound Modes, Claudio Oliveira Egalon Jan 1990

Injection Efficiency Of Bound Modes, Claudio Oliveira Egalon

Dissertations, Theses, and Masters Projects

Previous work on efficiency of light injection into the core of a fiber from a thin film and a bulk distribution of sources in the cladding, have made use of the fields of a weakly guiding fiber. This approximation simplifies the analysis of the power efficiency by introducing universal values for the eigenvalues of different fibers with same {dollar}V{dollar}-number, but can not predict accurately the behavior of the injected light into a fiber with arbitrary differences in indices of refraction. We have used the exact field solution in the expressions of the power efficiency, {dollar}P\sb{lcub}\rm eff{rcub}{dollar}, and analyzed its behavior …

Heavy Mineral Variability And Provenance Of The Virginia Inner Shelf And Lower Chesapeake Bay, L. J. Calliari, C. T. Fischler, C. R. Berquist Jr.

VIMS Books and Book Chapters

The mineral composition of the 3- to 4-phi (0.125 to 0.063 mm) size fraction of 49 surficial grab samples,located north and south of the entrance to Chesapeake Bay and of 38 surficial samples, located in the bay mouth, was determined during this study. Although up to 17 minerals were identified, principal components analysis indicated that seven minerals accounted for 96 percent of the composition variance in the bay samples. By using Q-mode factor analysis, three mineral composition end-members (factors) were selected from the sample data and provided an adequate description of the spatial variation in heavy-mineral composition. The end members …

Analysis Of Organic Pollutants In Sediments And Blue Crab (Callinectes Sapidus) Tissues : Final Report To Virginia State Water Control Board, John Greaves

Reports

The Elizabeth River is a highly industrialized waterway that divides the cities of Norfolk and Portsmouth at its confluence with the lower Chesapeake Bay. It is home to the largest Naval base on the East Coast, numerous ship repair facilities, bulk and containerized cargo facilities, industrial and urban activities and wood creosoting (preserving) operations (all except one have been abandoned). This degree of industrialization has resulted in the pollution of the river, with high concentrations of polynuclear aromatic hydrocarbons (PAH, Bieri et al., 1986). A major contributor to the pollution problem has been the wood processing industry which, due to …
