The Cape Darnley region in East Antarctica has been an area of scientific interest for a variety of disciplines over the last three decades. The recent acquisition of several high-resolution bathymetry datasets enabled the compilation of a detailed regional bathymetry grid. We present a high-resolution bathymetric compilation of the Cape Darnley region in East Antarctica, including areas of the Mac.Robertson Land shelf, slope and adjacent deep sea. A variety of data, single-beam and multibeam swath bathymetry and digitized depths from nautical charts were sourced from numerous institutions. The 100 m-resolution gridded bathymetric dataset improves previous bathymetric representations of the region and enables visualization of the seafloor morphology in unprecedented detail. The bathymetry grid has been constructed using a layered hierarchy approach based on the source of each dataset. This data compilation forms important baseline information for a range of scientific applications and end users including oceanographers, glacial modellers, biologists and geologists. The compilation will aid numerical modelling of ocean circulation, reconstruction of palaeo-ice streams and refinement of ice-sheet models.

南极洲东部达恩利角地区的测深汇编

在过去的三十年里，东南极洲的达恩利角地区一直是各种学科的科学兴趣领域。最近获得的几个高分辨率测深数据集使得能够编制详细的区域测深网格。我们展示了东南极洲达恩利角地区的高分辨率测深汇编，包括麦克罗伯逊陆架、斜坡和邻近的深海区域。来自海图的各种数据、单波束和多波束测深以及数字化深度来自众多机构。100 m 分辨率的网格测深数据集改进了该地区以前的测深表示，并能够以前所未有的细节可视化海底形态。测深网格是使用基于每个数据集源的分层层次方法构建的。该数据汇编为一系列科学应用和最终用户（包括海洋学家、冰川建模师、生物学家和地质学家）形成了重要的基线信息。该汇编将有助于海洋环流的数值模拟、古冰流的重建和冰盖模型的改进。
