Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Location: Potomac River from Chesapeake Bay to Washington DC, St. Mary's River, Breton Bay, Maryland, United States, North America, North Atlantic;
Principal Investigator(s): E. Ann Martin
Data Type(s): Biological Field Study: Experiments, Sampling: Biology, Sampling: Geology, Environmental Data: CTD, Environmental Data: Temperature, Sonar: Single Beam, Location-Elevation: Navigation
Scientific Purpose/Goals: Collect approximately 20 diver cores to be analyzed for stratigraphic distributions of 210Pb and selected trace metals.
Start Date: 1979-07-30
Start Port/Location: Lexington Park, MD
End Date: 1979-08-03
End Port/Location: Alexandria, VA
Equipment Used: Corer - slow, Grab sampler, Temperature and salinity, Echosounder, Loran-C
Information to be Derived: Samples and chemical analysis;
Summary of Activity and Data Gathered: Twenty sites were occupied. For each site, the following work was conducted: Cross section depth profile was run before the site was reoccupied for sampling and data collection. Salinity, conductivity, and temperature readings were obtained in the lower portion of the river. Diver core approx. 1 m in length and 12 cm in diameter obtained and split on board. Photographs and descriptions of each core were made. Subsamples from one half of cores were taken. Remaining half prepared for transport to Corpus Christi for x-radiography. Piston core taken, extruded, and described. Samples taken from selected cores. Bottom sampler was used to obtain sediment samples for trace metal analyses.
