Sea-Floor geology and character of Eastern Rhode Island Sound West of Gay Head, Massachusetts Sea-Floor geology and character of Eastern Rhode Island Sound West of Gay Head, Massachusetts
Gridded multibeam bathymetry covers approximately 102 square kilometers of sea floor in eastern Rhode Island Sound west of Gay Head, Massachusetts. Although originally collected for charting purposes during National Oceanic and Atmospheric Administration hydrographic survey H11922, these acoustic data and the sea-floor stations subsequently occupied to verify them (1) show the...

Surficial geology of the sea floor in Central Rhode Island Sound Southeast of Point Judith, Rhode Island Surficial geology of the sea floor in Central Rhode Island Sound Southeast of Point Judith, Rhode Island
The U.S. Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA) are working together to study sea-floor environments off the northeast coast of the United States. During 2008, NOAA survey H11996 collected multibeam echosounder data in a 65-square kilometer area in central Rhode Island Sound, southeast of Point Judith, Rhode Island. During 2010, the USGS...
