Sidescan sonar imagery of the winter marginal ice zone obtained from an AUV
The first Arctic under-ice sidescan sonar imagery from an autonomous underwater vehicle (AUV) has been obtained in the winter marginal ice zone of the East Greenland Current at 73degrees00'N, 11degrees47'W, using a Maridan Martin 150 vehicle operated from R/V Lance. First-year, multiyear,...
