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

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).

澳大利亚地球科学局（Geoscience Australia）通过整合两次多波束水文勘测数据，编制完成南极凯西站近岸区域的高分辨率水深栅格数据集。该数据集整合的勘测数据包含两项：1）2013/2014年度由澳大利亚皇家海军（Royal Australian Navy）实施的水文勘测，相关元数据记录为《2013年12月至2014年1月于凯西开展的RAN澳大利亚水文局HI545水文勘测》，编号为HI545_hydrographic_survey；2）2014/2015年度由澳大利亚地球科学局与澳大利亚皇家海军联合实施的水文勘测，相关元数据记录包括《2014年12月至2015年2月于凯西开展的RAN澳大利亚水文局HI560水文勘测》（编号HI560_hydrographic_survey）以及《2014年12月至2015年2月南极风车群岛与凯西区域海底制图勘测》（编号AAS_3326_seafloor_mapping_casey_2014_15）。该栅格数据集的单元格分辨率为1米，采用基于WGS84坐标系的UTM 49S投影格式存储。更多详细信息可访问澳大利亚地球科学局官网（详见相关链接）。
