Information Specialist(s):

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

Scientific Purpose/Goals: Test new SEA Submetrix transducer electronic modules (TEM) upgrades.


Start Port/Location: Army Corps of Engineers, Cape Cod Canal, MA

End Port/Location: Army Corps of Engineers, Cape Cod Canal, MA

Start Date: 2003-12-03

End Date: 2003-12-05

Equipment Used: DGPS, Sensor - SVP, Submetrix Sidescan sonar

Information to be Derived: Sea floor map;

Summary of Activity and Data Gathered: Ran a successful test of the TEM upgrades for the USGS 234 kHz SEA Submetrix system. Noted improved backscatter dynamic range when compared with the older modules, which in turn contributed to better interferometric solutions for the swath bathymetry. Collected 6 lines of Submetrix 2000 interferometric sidescan, along with 3 casts for sound velocity profiles. These data overlap with a data set collected by Benthos, Inc., in which they ran the new C3D system, an interferometric sidescan that Benthos is marketing. Will compare results from both systems.
