Processed gridded multibeam bathymetry 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 Qimera using XBT sound velocity profiles collected locally and gridded at 100m cell resolution for the entire survey. The data files are in GMT-compatible netCDF grid format and contain bathymetry data that 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.
