Bathymetry grids of Austrea1 survey (GA-0222)

The Austrea1 bathymetry survey, GA-0222 was acquired by Geoscience Australia onboard the IFREMER N/O L'Atalante from the 17th of December 1999 to the 11th of January 2000 using a Simrad EM12 Dual sonar system.
The main objectives of the shipboard program are to collect seabed and sub- bottom data in specific areas off southeast Australia for marine research (geological and biological), assessment of resource potential, regional marine zone planning and management, and to support Australia's claims under UNCLOS and to map the deep water part of a marine protected area in the Great Australian Bight (GAB).
This dataset contains a 100m resolution 32-bit geotiff of the Austrea1 survey, produced from the processed EM12D bathymetry data of the survey area using the CARIS HIPS and SIPS software.

Austrea1水深测量数据集GA-0222由澳大利亚地质调查局（Geoscience Australia）依托法国海洋开发研究院（IFREMER）的“阿塔兰特号”（L'Atalante）科考船，于1999年12月17日至2000年1月11日期间，使用西姆拉德EM12双频测深声呐系统（Simrad EM12 Dual）完成采集。
本次船载调查项目的核心目标涵盖：在澳大利亚东南部近海特定海域采集海底及海底以下数据，用于海洋地质与生物研究、资源潜力评估、区域海洋区划规划与管理；同时支撑澳大利亚在《联合国海洋法公约》（UNCLOS）框架下的海洋主张，并完成大澳大利亚湾（GAB）内海洋保护区的深水区域测绘工作。
本数据集包含本次Austrea1测量的100米分辨率32位GeoTIFF（GeoTIFF）格式数据，该数据由调查区域经处理后的EM12D水深测量数据通过CARIS HIPS与SIPS软件生成。
本数据集经澳大利亚地质调查局首席执行官授权发布。
