Antarctic and subantarctic hydrographic surveys by the RAN Australian Hydrographic Service

The RAN Australian Hydrographic Service have conducted hydrographic surveys near the coasts of the Australian Antarctic Territory and Heard Island and Macquarie Island.Data and metadata for hydrographic surveys by the RAN Australian Hydrographic Service in Antarctica and at Heard Island and Macquarie Island has been provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office. The survey locations in Antarctica were Mawson, Davis, Casey and Commonwealth Bay. The surveys were conducted since December 1993. Generally the surveys are denoted by a Hydrographic Instruction (HI) eg HI176. There is a metadata record for each survey from which the survey data and metadata can be obtained. The metadata records for the individual surveys are linked to this metadata record.The Australian Antarctic Data Centre has also had the soundings digitised from the fair sheets produced from earlier hydrographic surveys by the RAN Australian Hydrographic Service at Casey, Davis and Mawson. Metadata records describe the digitised soundings are also linked to this metadata record.

澳大利亚皇家海军海道测量局（RAN Australian Hydrographic Service）已在澳大利亚南极领地、赫德岛（Heard Island）与麦夸里岛（Macquarie Island）近岸海域开展海道测量作业。澳大利亚海道测量办公室（Australian Hydrographic Office）已将澳大利亚皇家海军海道测量局在南极洲、赫德岛及麦夸里岛开展的海道测量相关数据与元数据，移交至澳大利亚南极数据中心（Australian Antarctic Data Centre）。南极洲区域的测量点位涵盖莫森站（Mawson）、戴维斯站（Davis）、凯西站（Casey）及联邦湾（Commonwealth Bay），相关测量作业自1993年12月起启动。此类测量通常以《海道指令》（Hydrographic Instruction，简称HI）进行编号标识，例如HI176。每项测量均对应一条专属元数据记录，可通过该记录获取对应测量数据与元数据，各单项测量的元数据记录均关联至本元数据记录。此外，澳大利亚南极数据中心还完成了对澳大利亚皇家海军海道测量局早前在凯西、戴维斯及莫森站开展海道测量所生成的海图清样（fair sheets）中测深数据（soundings）的数字化工作，描述该数字化测深数据的元数据记录同样关联至本元数据记录。
