Processed gridded towed sidescan images (version 2) from the Guayamas Basin, Gulf of California acquired during Atlantis cruise AT15-54 (2009)

These gridded sidescan images were derived from towed IMI30 Sidescan Sonar data collected during Atlantis expedition AT15-54 conducted in 2009 (Chief Scientist: Dr. Dan Lizarralde). The data files are of JPEG format and were processed after data collection. The data files were generated by the Hawaii Mapping Research Group (HMRG) and were acquired as part of the project called Off-Axis Sills of Guaymas Basin: Implications for Thermogenic-Carbon Flux of a Sedimented Rift Basin, with funding provided by NSF grant OCE07-51901.
