Dataset description: 2010-012-FA-SO-001-01

XSonar/ShowImage software was used to correct for geometric and radiometric distortions in the raw sidescan data (Danforth, 1997), and PCI Geomatica (version 10.1) software was used to create georeferenced mosaics of the final, processed data. Gray-scale GeoTIFF images of the mosaics were produced at 1-m resolution. Sidescan-sonar data were acquired along approximately 1,750 km of tracklines during the 2010 cruises, yielding a total mosaic area of about 260 km2.
