A high resolution bathymetric survey of Muskeget channel and surroundings was completed in fall of 2010 (Denny et al., 2012). The chief survey scientist was Jane Denny from the USGS Woods Hole Science Center (WHSC). Rich Signell (USGS, WHSC) helped coordinate the survey design. The survey was conducted using an interferometric sonar unit which can measure bathymetry along a swath on either side of the ship track with a width of roughly seven times the water depth. The goals of the survey were to obtain a baseline high resolution bathymetry dataset for Muskeget Channel, characterize the large scale bedforms in the Channel surroundings, and characterize the bedforms in the vicinity of the two potential routes by which the installation would be connected with Martha's Vineyard.
