The Pacific Seafloor Mapping Project has conducted a number of surveysin the eastern Pacific Ocean, Hawaii, Gulf of Mexico, and Lake Tahoe, whichis on the border of California and Nevada. The two types of data collectedinclude;
These data are of critical importance to groups as diverse as marinehabitat biologists, state and local authorities setting regulations on sea-flooruses, school children and their teachers. The new high-resolution base mapsproduced by this project will be used for:
Ongoing research is attempting to derive better relationships betweenthe backscatter collected from a multibeam mapping system and the sea-floorgeology. The ultimate goal of this research is to convert the backscattermaps into geologic maps.
