Summary for Field Activity Number 2003-054-FA

Area of Operations: Cape Cod Canal, Massachusetts, United States, North America, North Atlantic

Dates: December 03, 2003 to December 05, 2003

Objectives: Test new SEA Submetrix transducer electronic modules (TEM) upgrades.

Type of Activity: Sea floor mapping

Information to be derived: Sea Floor Map

Summary: 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.
