Equipment Used
The major objective of cruise IS-1-98-LT was to map the bathymetry of
Lake Tahoe, California-Nevada to fulfill a commitment made during the Lake Tahoe
Presidential Forum in 1997
Information to be Derived
Bathymetry, backscatter, slope, sediment volumes,  interpreted geology, etc
Completed survey and processed bathymetry and backscatter data of approximately 
90 percent of Lake Tahoe.
