Processed gridded towed sidescan data from the Guayamas Basin, Gulf of California acquired during Atlantis cruise AT15-54 (2009)

This gridded sidescan data set was derived from towed IMI30 Sidescan Sonar data collected during Atlantis expedition AT15-54 conducted in 2009 (Chief Scientist: Dr. Dan Lizarralde). The data files are of NetCDF:GMT format and were processed after data collection. The data files were generated by the Hawaii Mapping Research Group (HMRG) and were acquired as part of the project called Off-Axis Sills of Guaymas Basin: Implications for Thermogenic-Carbon Flux of a Sedimented Rift Basin, with funding provided by NSF grant OCE07-51901.本格网化侧扫数据集源自2009年执行的亚特兰蒂斯号AT15-54科考航次所采集的拖曳式IMI30侧扫声呐（Sidescan Sonar）数据，该航次首席科学家为丹·利扎拉德博士。数据文件采用NetCDF:GMT格式，且在数据采集完成后经过处理。本数据集由夏威夷测绘研究组（Hawaii Mapping Research Group, HMRG）生成，其采集工作隶属于名为"瓜伊马斯盆地轴外岩床：沉积型裂谷盆地的热成因碳通量启示"的研究项目，该项目由美国国家科学基金会（National Science Foundation, NSF）资助项目编号OCE07-51901提供资金支持。
