USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 2005-005-FA

Other ID: none

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Walter Barnhardt

Affiliate Investigator(s): Massachusetts Office of Coastal Zone Management

Information Specialist(s):

Data Type(s): Biological Field Study: Experiments, Biological Field Study: Surveys, Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Sub Bottom Profiler, Sonar: Multibeam, Sonar: Sidescan, Sonar: Sound Velocity, Visual Identification: Species ID

Scientific Purpose/Goals: Sea floor mapping to: 1) support management of ocean resources; 2) clarify the post-glacial history of sea-level change in the region; 3) reconstruct coastal environments and quantifying rates of change over the last few thousand years; and 4) develop a sediment budget for the coastal system, which is experiencing chronic erosion.


Start Date: 2005-09-06

Start Port/Location: Woods Hole, MA

End Date: 2005-09-21

End Port/Location: Woods Hole, MA

Equipment Used: SeaBOSS, Digital camera, Real Time Kinematic GPS, EdgeTech Subbottom 512i, SWATHplus-M 234 kHz, Klein 595 100/500kHz sidescan sonar, Sensor - MVP30

Information to be Derived: Grain size analysis; Sea floor map; Bathymetric maps; high-resolution geologic maps;

Summary of Activity and Data Gathered: The new remotely operated vehicle (ROV) was deployed for the first time to successfully recover a sound-velocity profiler that was lost during a cast. We collected 100% coverage of sea floor with bathymetry and sidescan sonar data, approximately 1000 km of seismic reflection profiles, and grab samples and bottom photography/video at 93 stations. Cruise focused on nearshore areas in water depths of 5-25 m to complete the surficial mapping that was begun in 2003 (SAIC contract multibeam). Sub-bottom profiles were collected throughout entire study area in water depths of 5-90 m.
