Davis Coastal Seabed Mapping Survey, Antarctica (GA4301 / AAS2201 / HI468) - High Resolution Bathymetry 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 modelling 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）由澳大利亚南极署所属工作船“霍华德·伯顿号”于2010年2月至3月完成数据采集，作为澳大利亚南极科学（AAS）项目2201——“南极近岸海洋底栖群落的自然变异性与人为诱发变化”的组成部分。本调查由澳大利亚地球科学局、澳大利亚南极署及澳大利亚水文局（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兹丘陵沿海区域的多波束测深与反向散射数据，以辅助解析海底特征与底栖生境，为戴维斯站周边海域水动力运动模拟提供基础依据，并更新与扩充该区域的航海海图。
