Resistivity, Magnetic Susceptibility And Sediment Characterization Of The York River Estuary In Support Of The Empirical Investigation Of The Factors Influencing Marine Applications Of Emi (Year 2 Of Serdp Project Mr-2409) Final Report., Grace M. Massey, Carl T. Friedrichs Jan 2017

Resistivity, Magnetic Susceptibility And Sediment Characterization Of The York River Estuary In Support Of The Empirical Investigation Of The Factors Influencing Marine Applications Of Emi (Year 2 Of Serdp Project Mr-2409) Final Report., Grace M. Massey, Carl T. Friedrichs

Reports

Vessel and personnel support was provided for a series of cruises to three salinity regimes along the York River. Data and samples from a standard suite of hydrographic and sedimentological measurements, as well as electrical resistivity and magnetic susceptibility, were collected and analyzed for each location. These cruises provided opportunities to obtain information that is being used to quantify the unique marine contributions to the early time TEM noise, including conductivity variations in the water and variability in bottom sediment properties in real marine environments, for use in the parallel modeling and electromagnetic-induction sensor work ongoing in the same project ...

The Effects Of Sea Level Rise On Tidal Wetlands In The Lynnhaven River Watershed, Marcia Berman, Harry Berquist, Center For Coastal Resources Management, Virginia Institute Of Marine Science Jan 2009

The Effects Of Sea Level Rise On Tidal Wetlands In The Lynnhaven River Watershed, Marcia Berman, Harry Berquist, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

This study classified tidal wetlands for the Lynnhaven Watershed using remote sensing techniques and high resolution imagery from 2007. This updated delineation of wetlands, was used in conjunction with a simplistic geospatial elevation model to quantify the potential loss of wetlands under various sea level rise scenarios.The study revealed that using conservative estimates of sea level rise, nearly all wetlands would be lost by the year 2100. Projecting sea level rise into the future can be considered speculative, nevertheless such predictions are necessary to begin managing for and planning for climate change impacts. Evidence from this study suggests that ...


Hypoxia In The York River, 1991, A. Y. Kuo, Bruce Neilson, J. M. Brubaker, E. P. Ruzecki May 1993

Hypoxia In The York River, 1991, A. Y. Kuo, Bruce Neilson, J. M. Brubaker, E. P. Ruzecki

Reports

This data report describes field studies conducted during the summer of 1991 by the Virginia Institute of Marine Science (VIMS) when both the physical environment and the dissolved oxygen regime were monitored, with the objective of better understanding how physical transport processes affect DO. The 1991 data sets will be presented here. Analysis and interpretation of the data is the subject of other scientific reports.


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 ...


Data Report : Hypoxia In The York River, 1988-1989, G. M. Sisson, A. Y. Kuo, J. M. Brubaker Jan 1991

Data Report : Hypoxia In The York River, 1988-1989, G. M. Sisson, A. Y. Kuo, J. M. Brubaker

Reports

As part of the hypoxia program of the Virginia Chesapeake Bay Initiatives, the Division of Physical Oceanography of the Virginia Institute of Marine Science (VIMS) conducted a series of measurements in the York River estuary. The measurements were made in summer, 1988 and 1989. Two types of measurements were conducted in each year: measurements at moored stations and measurements by slackwater surveys. The former collected data for investigation of dissolved oxygen (DO) variation, and associated physical parameters, in an intratidal time scale, as well as for studying the vertical distributions of the measured parameters. The latter collected data for spatial ...

The Virginia Institute of Marine Science (VIMS) installed two remote monitoring stations in the lower reaches of the Rappahannock River to obtain continuous temperature and salinity measurements near the surface and the bottom. The first station was installed at the base of a concrete support of the Rappahannock River (Norris) Bridge, near the mouth of the, river (Figure 1). The second station was installed on the base of Navigation Aid Tower Number 9 just off of Smokey Point, roughly 11 nautical miles upstream from the Norris Bridge.
