Maps of Near-Bottom Bathymetry Data from the Alarcon Rise Spreading Center

This data set was acquired with a Reson SeaBat 7125 Multibeam Sonar during Zephyr expedition ZPR1204 conducted in 2012 and RCSN234 conducted in 2015 (15 surveys) (Chief Scientist: Dr. David Clague, Investigators: Dr. David Caress, Jennifer Paduan, Dr. David Clague, Dr. Ronald Spelz-Madero). These data files are of PNG format and include Bathymetry data that were processed after acquisition. Maps are in WGS-1984 geographic coordinate system. Navigation is DVL/USBL, adjusted with MBSystem in post-processing.本数据集由Reson SeaBat 7125型多波束声呐（Reson SeaBat 7125 Multibeam Sonar）采集，采集工作依托2012年开展的Zephyr航次ZPR1204与2015年开展的Zephyr航次RCSN234完成，共计15次勘测任务。首席科学家为David Clague博士，研究人员包括David Caress博士、Jennifer Paduan、David Clague博士与Ronald Spelz-Madero博士。本次数据文件采用PNG格式，包含采集后经过处理的测深数据（Bathymetry）。地图采用WGS-1984地理坐标系。导航数据采用DVL/USBL定位方案，并在后期处理中通过MBSystem完成了校准修正。
