Other ID: R-34-08-MA

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Lawrence Poppe

Affiliate Investigator(s):

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

Data Type(s): Location-Elevation: Navigation, Seismics: Boomer, Seismics: Sub Bottom Profiler

Scientific Purpose/Goals: Ground truth NOAA hydrographic survey H11346 of the entrance to Edgartown Harbor with seismic reflection. One day primarily employed the Uniboom system; one day primarily employed the Knudsen Chirp.


Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 2008-08-18

End Date: 2008-08-20

Equipment Used: Knudsen CHIRP Sub-bottom Profiler, DGPS, Boomer, Single channel hydrophone

Information to be Derived:

Summary of Activity and Data Gathered: Equipment problems prevented data acquisition on August 18, but 57 km of Knudsen Chirp seismic reflection profiles and 17 km of Uniboom seismic reflection profiles were collected along tracklines on August 19-20.

Staff: David Foster, Thomas O'Brien
