Description

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.
