An Assessment Of Wildlife Utilization Between A Man-Made Marsh, An Adjacent Natural Marsh, And A Nearby Natural Marsh In Virginia, Kirk J. Havens, Lyle M. Varnell, Julie G. Bradshaw Nov 1992

An Assessment Of Wildlife Utilization Between A Man-Made Marsh, An Adjacent Natural Marsh, And A Nearby Natural Marsh In Virginia, Kirk J. Havens, Lyle M. Varnell, Julie G. Bradshaw

Reports

The present study investigates the functions and values of man-made and natural tidal wetlands. The study is among the first to use simultaneous sampling techniques to investigate animal use preference between man-made and adjacent natural tidal wetlands.


Status Of The Public Oyster Resource Of Virginia - Fall 1992, Bruce J. Barber Nov 1992

Status Of The Public Oyster Resource Of Virginia - Fall 1992, Bruce J. Barber

Reports

oysters have been harvested from Virginia waters as long as humans have i):'lhabited the area. Depletion of natural stocks in the late 1880's led to the establishment of regulations by public fisheries agencies. A survey of bottom areas in which oysters grew naturally was completed in 1896 under the direction of Lt. Baylor, USN. These areas (over 243,000 acres) were set aside by legislative action for public use and have come to be known as the Baylor survey Grounds or Public oyster Grounds of Virginia, and are presently administered by the Virginia Marine Resources commission (VMRC). Twice a year the …


Dissolved Oxygen Measurements In The Machipongo River System Near Willis Wharf, Virginia, Bruce Neilson, Cheol Mo, Rodney Jackson Sep 1992

Dissolved Oxygen Measurements In The Machipongo River System Near Willis Wharf, Virginia, Bruce Neilson, Cheol Mo, Rodney Jackson

Reports

Most aquatic organisms require· oxygen to survive and consequently, the dissolved oxygen (DO) content of the water is one of the most important measures of water quality. Sources of oxygen are the atmosphere and photosynthesis. Oxygen is consumed by plants and animals during respiration and by microorganisms that decompose organic matter. The more sources and sinks of oxygen, the more difficult it is to understand and predict the oxygen dynamics of a river system. Grossly polluted systems turn out to be quite simple, because the pollutant source dominates. Natural, unimpacted systems often show a balance between a number of sources …

Temporal And Spatial Variations In Chesapeake Bay Water Quality: A Video Data Report, Sarah E. Rennie, Bruce Neilson May 1992

Temporal And Spatial Variations In Chesapeake Bay Water Quality: A Video Data Report, Sarah E. Rennie, Bruce Neilson

Reports

Over the past two years we have been developing computer programs to investigate various scientific visualization techniques as applied to estuarine data. The original impetus was to be able to visualize the results of the three-dimensional hydrodynamic model under development at the Virginia Institute of Marine Science, College of William and Mary (VIMS). We quickly recognized the superior ability of certain graphic approaches, especially pseudocolor animation, to efficiently transmit a tremendous amount of information to the viewer, allowing the scientist to gain an insight into the dynamics of the data not otherwise available. We decided to apply this technique to …


Water Quality In Chesapeake Bay : Virginia Portion, Water Year 1988 : A Report To The Virginia Water Control Board, Kevin Curling, Bruce Neilson Apr 1992

Water Quality In Chesapeake Bay : Virginia Portion, Water Year 1988 : A Report To The Virginia Water Control Board, Kevin Curling, Bruce Neilson

Reports

The purpose of this report is to characterize water quality conditions during the 1988 water year, October 1987 through September 1988. For the most part, the information is provided in graphical format. Only data for the Virginia portion of Chesapeake Bay is included. No data analysis or interpretation is included, since this is the stated purpose of several other reports. This report will be useful to both scientists and managers who need ready access to some portion of the data on a regular basis. With this report it is possible to quickly examine seasonal patterns, compare conditions at two stations, …


Bank Erosion Study, C. Scott Hardaway Jr., George R. Thomas, J. B. Glover, J. B. Smithson, Marcia Berman, A. K. Kenne Apr 1992

Bank Erosion Study, C. Scott Hardaway Jr., George R. Thomas, J. B. Glover, J. B. Smithson, Marcia Berman, A. K. Kenne

Reports

The Bank Erosion Study was designed to evaluate eroding fast land bank shorelines as contributors of sand, silt and clay and total nitrogen and total phosphorous introduced into the Chesapeake Bay estuarine system. In addition, the extent and effectiveness of erosion control measures were evaluated for selected shoreline reaches. Fastland banks are the uplands along the shorelines that are composed of semi-consolidated sediments. This study evaluates about 2000 miles of primary tidal shoreline in the Virginia portion of the Chesapeake Bay estuarine system for areas of fast land bank erosion. Primary tidal shorelines are those along the main stem of …

Oyster Spatfall In Virginia Waters: 1991 Annual Summary, Bruce J. Barber Jan 1992

Oyster Spatfall In Virginia Waters: 1991 Annual Summary, Bruce J. Barber

Reports

The Virginia Institute of Marine Science (VIMS) conducts surveys of oyster spatfall (or "setting") in Virginia waters throughout the summer reproductive period. This survey provides an estimate of the potential of a particular area for receiving a "strike" or set of oysters on the bottom and helps define the timing of setting events. Information obtained from this effort is valuable to the Virginia Marine Resources Commission (VMRC) for its shell repletion program, and to private oyster growers, both of which are interested in maximizing the timing of shell planting. In addition, by maintaining a long-term data base, trends in spatfall …
