| Purpose | 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. | ||||||||
| Location | Merrimack Embayment, Massachusetts, Gulf of Maine, United States, North America, North Atlantic; | ||||||||
| Summary | 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. | ||||||||
