Subbottom and Sidescan Sonar Data Acquired in 2015 From Grand Bay, Mississippi and Alabama

Grand Bay Alabama and Mississippi were surveyed between May and June 2015, using an Edgetech chirp 424 subbottom profiler and a Klein 3900 sidescan sonar. The objective was to characterize the geologic framework of recent estuarine sediment accumulation in the bay. This data release includes the raw chirp subbottom Society of Exploration Geophysicists (SEG Y) data files, sidescan data files in eXtended Triton Format (XTF), and a processed sidescan sonar mosaic GeoTIFF.
