Supporting documentation:

Operations Area: Narragansett OPAREA

Lat/Lon: 40° 0.0′ N / 70° 0.0′ W

Depth Range: 175 / 1500

Will the vessel be operating within 200 NM of a foreign country? NA
Are visas or special travel documents required? no

Science objectives

Research and Discovery of the characterstics of the seafloor in the area of operation, such as number of sediment layers, the thickness of these layers and their geoacoustical properties such as sound speed, density, and attenuation.

Science Activities

Deployment of acoustic and oceanographic arrays.  Deployment of towed acoustic sources and SUS explosive sources.   The acoustic data are then analyzed within an acoustic propgation model for the information they contain about the seabed properties.
