Chesapeake Bay Diamond Shoal Project. This project was for the purpose of mapping oyster habitat for the Maryland Department of Natural Resources. This continued a function of the Coast Survey that began in the 1870's with mapping the oyster beds of Maryland, Virginia and many of the eastern seaboard and Gulf Coast states.

This image is a false-color image of backscatter intensity over Diamond Shoal which gives an indication of bottom materials. The backscatter is from sidescan sonar emissions.
6270 thumbnail picture
Sidescan sonar imagery was combined with multi-beam sounding data to produce 3-D reflectivity maps which were indicative of bottom materials.
6271 thumbnail picture
Sub-meter backscatter resolution used to help determine bottom types at Diamond Shoal.
6272 thumbnail picture
Sidescan sonar backscatter data combined with 3-D multi-beam data produced this map which showed a direct relationship between depth and type of bottom material in this area.
6273 thumbnail picture
Multi-beam false color and printed depth presentation of Diamond Shoal.
6274 thumbnail picture
