Davis Coastal Seabed Mapping Survey, Antarctica (GA-4301 / AAS2201 / HI468) - High Resolution Backscatter Grids

The Davis Coastal Seabed Mapping Survey, Antarctica (GA-4301 / AAS2201 / HI468) was acquired by the Australian Antarctic Division workboat Howard Burton during February-March 2010 as a component of Australian Antarctic Science (AAS) Project 2201 - Natural Variability and Human Induced Change on Antarctic Nearshore Marine Benthic Communities.The survey was undertaken as a collaboration between Geoscience Australia, the Australian Antarctic Division and the Australian Hydrographic Service (Royal Australian Navy). The objectives were to provide multibeam bathymetry and backscatter of the coastal region of the Vestfold Hills around Davis Station, Antarctica, to aid the understanding of sea bed character, benthic habitats, provide a basis for hydrodynamic modeling of water movement around Davis, and to update and extend the navigational charts of the region.

南极戴维斯海岸海底测绘调查（GA-4301 / AAS2201 / HI468）由澳大利亚南极局工作船“霍华德·伯顿号”于2010年2月至3月完成数据采集，该作业是澳大利亚南极科学（Australian Antarctic Science, AAS）项目2201——“南极近岸海洋底栖群落的自然变异与人为诱发变化”的组成部分。本次调查由澳大利亚地球科学局、澳大利亚南极局与澳大利亚水文局（澳大利亚皇家海军）联合开展。调查目标为获取南极戴维斯站周边韦斯特福尔德丘陵（Vestfold Hills）沿岸海域的多波束测深与声学后向散射数据，以助力解析海底特征与底栖生境，为戴维斯站周边水体运动的水动力模拟提供基础支撑，并更新与拓展该区域的航海海图。
