The major objective of this cruise was to collect approximately 10 to 20 diver cores to be analyzed for stratigraphic distributions of Pb-210 and selected trace metals.
Location
Potomac River, Wicomico River, Port Tobacco River, Chesapeake Bay, Maryland, Virginia, Washington D.C., United States, North America, North Atlantic;
Summary
The diver corer with a split core barrel worked extremely well and the cores obtained showed only minimal disturbance. The cruise was very successful, and the divers did an excellent job in all respects. 17 sites were occupied and the following were obtained at each site: 1. A cross section depth profile was run; 2. A diver core (1 m x 12 cm diameter) was taken, split, subsampled and archive half placed in D-tube for transport to Corpus for X-radiography; 3. A Benthos gravity core was taken, extruded, described and sampled on deck; 4. Salinity, conductivity and temperature measurements were made in lower portions of the river. S/C/T: 34; Daily log #67.
