SKQ201816S Backscatter:Acoustic
Processed acoustic backscatter data from the Alaska-Aleutians area acquired during Sikuliaq cruise SKQ201816S (2018)
This data set was derived from Kongsberg EM302 multibeam sonar data acquired during the 2018 R/V Sikuliaq cruise SKQ201816S (Co-Chief Scientists: Anne Sheehan and Doug Wiens. Investigators: Anne Becel, Anne Sheehan, William Danforth, Emma Myers, Peter Haeussler, Geoff Abers, Aubreya Adams, Emily Roland, Susan Schwartz, Donna Shillington, Spahr Webb, Douglas Wiens, Lindsay Worthington). The data files were processed in QPS FMGT (Geocoder Toolbox) and gridded at 100m cell resolution for the entire survey. The data files are in GeoTIFF grid format and contain acoustic backscatter intensity values ranging from 0 (black) – 255 (white). The data has been processed with the help of the Apply-to-Sail participants: Samantha Hansen, Natalia Ruppert, Tiegan Hobbs, Amanda Price, Jefferson Yarce, Heather Shaddox, Bethany Essary, and Shannon Hendricks. The data set was generated as part of the project called the Alaska Amphibious Community Seismic Experiment (AACSE). Funding was provided by NSF award OCE16-54568.

The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).
