Hydrography and Hydrodynamics of Virginia Estuaries V: A Report on the Prototype Data Collected in the Rappahannock River and Mobjack Bay for the Chesapeake Bay Model Study

This report describes methods used to collect and process tidal, current and salinity data for the Rappahannock River and Mobjack Bay, Virginia. Data was collected as part of a study which investigates water utilization and control in the Chesapeake Bay Basin. Field procedures, equipment and data processing techniques are discussed in full

Data Report: Operation York River, 1969

A field survey was carried out in October 1969 to gather field data from the Mattaponi, Pamunkey and York rivers in order to construct mathematical models for salinity and dissolved oxygen. The results of the field operation are presented, together with a description of the methods and instruments used in the data collection and analysis

Oceanographic Data Collected in the Chesapeake Bight of the Virginian Sea from 1966 though 1969

This report is intended to make unsynthesized oceanographic data readily available to the scientific community. 3 Similar reports are envisioned which will include physical, chemical, biological and geological data collected by personnel of the Virginia Institute ·of Marine Science in areas of the continental shelf, and coastal zone to include beaches, wetlands, estuaries and tidal rivers - areas in which the Commonwealth of Virginia has a vested interest

Hypoxia in the York River, 1991

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

The effects of the Agnes flood on the salinity structure of the lower Chesapeake Bay and contiguous waters

The transient response of salinity distribution in lower Chesapeake Bay to flood waters from Tropical Storm Agnes is studied in terms of a two-layered, partially mixed estuary. Prior to 30 June 1972, surface salinities were well depressed throughout the Bay while those at the bottom near the Bay mouth were not depressed by 5 July. This resulted in a highly stratified situation normally found in the spring of the year. Stratification decreased when bottom waters were flushed down-bay by the flood (on 5 to 10 July for the region south of New Point Comfort). The rebound of salinity structure started immediately after the passage of the flood water which otherwise retarded up-bay movement of bottom waters. This rebound began on 13 July near the Bay mouth and progressed up-bay reaching the mouth of the Potomac River by 20 July. During this period, surface salinity remained low, resulting in strong stratification again. The recovery of surface salinity by tidal mixing finally weakened stratification to a near normal salinity structure by the end of August. The large mass of flood water leaving the Bay mouth is treated as a natural tracer release. The distribution of flood water on the continental shelf indicates that pulses of freshened surface water left the Bay on ebb tide and were separated from one another by intrusion of saltier shelf water on flood tide. During the period when the wind speed was below 4 m/s, the flood water remained in the upper 10 meters of the water column and traveled southward with a speed of 80 cm/sec.https://scholarworks.wm.edu/vimsbooks/1049/thumbnail.jp
