USGS - science for a changing world

USGS Coastal and Marine Geology Program

Field Activity Details for field activity 2008-039-FA

Other ID: J-39-08-LI

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Lawrence Poppe

Affiliate Investigator(s): Office of Coast Survey, National Oceanic and Atmospheric Administration

Information Specialist(s): Lawrence Poppe, Nancy K. Soderberg

Data Type(s): Sonar: Multibeam, Sonar: Sound Velocity, Sonar: Sidescan, Location-Elevation: Navigation

Scientific Purpose/Goals: The ship will be acquiring multibeam bathymetry and backscatter datasets to update nautical charts. USGS participation facilitates eventual acquisition of these datasets for geological sea floor mapping applications.


Start Port/Location: New London, CT

End Port/Location: Woods Hole, MA

Start Date: 2008-09-15

End Date: 2008-09-25

Equipment Used: DGPS, Klein 531 sidescan, Simrad EM 1000, Reson 7125

Information to be Derived: Sea floor maps

Summary of Activity and Data Gathered: One bathymetric survey was completed; two other surveys were partially completed. Although no USGS data were generated during this cruise, grids and imagery will eventually be obtained when data processing is complete.
