A high resolution bathymetric grid of the nearshore area at Casey station, Antarctica

These data are available from the Geoscience Australia website.A high resolution bathymetric grid of the nearshore area at Casey station, Antarctica was produced by Geoscience Australia by combining data from two multibeam hydrographic surveys: 1) A survey conducted by the Royal Australian Navy in 2013/14. Refer to the metadata record 'Hydrographic survey HI545 by the RAN Australian Hydrographic Service at Casey, December 2013 to January 2014' with ID HI545_hydrographic_survey.2) A survey conducted by Geoscience Australia and the Royal Australian Navy in 2014/15. Refer to the metadata record 'Hydrographic survey HI560 by the RAN Australian Hydrographic Service at Casey, December 2014 to February 2015' with ID HI560_hydrographic_survey and the metadata record 'Seafloor Mapping Survey, Windmill Islands and Casey region, Antarctica, December 2014 - February 2015' with ID AAS_3326_seafloor_mapping_casey_2014_15.The grid has a cell size of one metre and is stored in a UTM Zone 49S projection, based on WGS84.Further information is available from the Geoscience Australia website (see a Related URL).

本数据集可从澳大利亚地质调查局（Geoscience Australia）官网获取。澳大利亚地质调查局通过整合两次多波束水文测量数据，构建了南极凯西站近岸区域的高分辨率水深栅格数据集：1) 2013/2014年度由澳大利亚皇家海军（Royal Australian Navy，以下简称RAN）开展的水文测量任务，相关元数据记录为ID为HI545_hydrographic_survey的《2013年12月至2014年1月于凯西站开展的RAN澳大利亚水文服务局HI545号水文测量》；2) 2014/2015年度由澳大利亚地质调查局与澳大利亚皇家海军联合开展的水文测量任务，相关元数据记录包括：ID为HI560_hydrographic_survey的《2014年12月至2015年2月于凯西站开展的RAN澳大利亚水文服务局HI560号水文测量》，以及ID为AAS_3326_seafloor_mapping_casey_2014_15的《2014年12月至2015年2月于南极风车群岛与凯西地区开展的海底测绘调查》。该栅格数据集的格网分辨率为1米，采用基于WGS84坐标系的通用横轴墨卡托（Universal Transverse Mercator，简称UTM）49S投影格式存储。更多相关信息可通过澳大利亚地质调查局官网获取（详见相关链接）。
