Multibeam Sonar Surveys

Multibeam sonar is the state-of-the-art technology used by NOAA and other organizations for mapping water depths, or bathymetry. Below is a sortable list of multibeam sonar datasets from 2003-2013 that are available for the Northeast region. Hover over a listing to see an index map. Click on a record for more information and a link to download the data. Downloads must be selected one at a time, and only files smaller than 1GB can be downloaded. To download large files, go to the file download page or the NOAA National Geophysical Data Center.
