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.

本数据集源自于2018年R/V Sikuliaq巡航SKQ201811S期间采集的Kongsberg EM302多波束声纳数据（联合首席科学家：Spahr Webb及Lindsay Worthington，研究人员：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）。数据文件经QPS FMGT（地理编码工具箱）处理，并以100米单元格分辨率对整个调查区域进行网格化。数据文件采用GeoTIFF网格格式，包含从0（黑色）至255（白色）的声学后向散射强度值。数据处理得益于Apply-to-Sail参与者：Collin Brandl、Enrique Chon、David Heath、Robert Martin-Short、Kelly Olsen及Holly Rotman。该数据集作为名为阿拉斯加两栖社群地震实验（Alaska Amphibious Community Seismic Experiment，简称AACSE）项目的一部分生成。项目资助由NSF资助项目OCE16-54568提供。
