Bathymetry grid (5 m cell size) for Lord Howe Island and Balls Pyramid shelves, southwest Pacific Ocean

This dataset is a seamless, high resolution (5m cell size) bathymetry model of Lord Howe Island and Balls Pyramid. This dataset provides detailed depth information from the island shoreline to the shelf drop off.

This bathymetry dataset integrates multibeam echo sounder data together with depth derived from satellite imagery. Multibeam echo sounder data were acquired aboard two voyages on the CSIRO Marine National Facility R.V. Southern Surveyor in 2008 and 2013. Shallow data was derived from World View II satellite imagery of Lord Howe Island collected in 2013. Inshore depth data around Balls Pyramid derived from Quickbird imagery (collected in 2009) was excluded from this dataset. Gaps in data coverage were interpolated using Natural Neighbor in ArcGIS 10.4. Data were clipped at 0 to 300 m depth.

本数据集为洛夫海岛及其巴尔斯尖塔的无缝、高分辨率（5米网格大小）地形模型。该数据集提供了从岛屿海岸线至大陆架边缘的详细深度信息。该地形数据集整合了多波束测深仪数据与卫星影像获取的深度信息。多波束测深仪数据于2008年和2013年分别在我国CSIRO海洋国家设施“南方巡洋舰”R.V.号上的两次航行中采集。浅层数据源自2013年收集的洛夫海岛World View II卫星影像。巴尔斯尖塔附近近岸深度数据，由2009年收集的Quickbird影像获取，已从本数据集中排除。数据覆盖空白区域采用ArcGIS 10.4中的自然邻域插值方法进行填补。数据深度范围为0至300米。有关方法的详细描述见以下开放获取出版物，可通过以下链接访问：http://www.mdpi.com/2076-3263/8/1/11/htm
