SKQ201811S Backscatter:Acoustic
GeoPRISMS:Funded
Processed acoustic backscatter data from the Alaska-Aleutians area acquired during Sikuliaq cruise SKQ201811S (2018)
This data set was derived from Kongsberg EM302 multibeam sonar data acquired during the 2018 R/V Sikuliaq cruise SKQ201811S (Co-Chief Scientists: Spahr Webb and Lindsay Worthington. 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: Collin Brandl, Enrique Chon, David Heath, Robert Martin-Short, Kelly Olsen, and Holly Rotman. 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.
