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2018年R/V Sikuliaq号科考船航次SKQ201811S采集的康斯伯格EM302多波束声呐（Kongsberg EM302 multibeam sonar）数据，该航次联合首席科学家为Spahr Webb与Lindsay Worthington，参与研究的人员包括Anne Becel、Anne Sheehan、William Danforth、Emma Myers、Peter Haeussler、Geoff Abers、Aubreya Adams、Emily Roland、Susan Schwartz、Donna Shillington、Spahr Webb、Douglas Wiens及Lindsay Worthington。数据文件通过QPS FMGT（Geocoder Toolbox）完成处理，并对全部调查区域以100米像元分辨率进行网格化处理。数据文件采用GeoTIFF网格格式，存储的声学背散射强度值取值范围为0（对应黑色）至255（对应白色）。本数据集的处理工作得到了Apply-to-Sail项目参与者Collin Brandl、Enrique Chon、David Heath、Robert Martin-Short、Kelly Olsen及Holly Rotman的协助。本数据集是阿拉斯加两栖社区地震试验（Alaska Amphibious Community Seismic Experiment, AACSE）项目的研究成果之一，相关研究由美国国家科学基金会（National Science Foundation, NSF）项目编号OCE16-54568资助。
