Processed acoustic backscatter data from the US Atlantic Margin, Langseth cruise MGL1512 (year 2015, investigators James Gardner and Brian Calder)

Processed acoustic backscatter grid derived from Kongsberg EM122 multibeam swath sonar data collected along the Eastern North America Atlantic margin. Data collected in 2015 during Langseth cruise MGL1512 as part of a U.S. Law of the Sea Extended Continental Shelf survey (investigators James Gardner and Brian Calder). The data file is in netCDF:GMT format.
