During the 1990’s, Dr. Maynard Nichols and colleagues at the Virginia Institute of Marine Science compiled digital databases of sediment observations in the Chesapeake Bay and other coastal bays and rivers. These projects were performed under several cooperative agreements with NOAA, EPA and USGS. This particular dataset covers the Chesapeake Bay for bulk properties and contaminants. Additional references are provided below. The original files and filenames are provided without edit. See the readme.txt file for overall explanation of the datasets and individual .DOC files for the data dictionary and further data processing information for each waterbody.


Digital files of bulk sediment properties, grain size, water content, organic content and trace metals in the Virginia portion of the Chesapeake Bay and its Tributaries. Various dates, 1968 through 1989.

Surveyed areas: Chesapeake Bay, Chester River, Choptank River, James River, Patuxent River, Potomac River, Rappahannock RIver and York River.
