This dataset contains the processed bathymetric dataset from the Lord Howe and Lord How Island survey area held by Geoscience Australia. This dataset includes multibeam echosounder data and was gridded at 50m resolution of the Lord Howe survey area and a 10m resolution of Lord Howe Island, based on the optimal resolution for the depth range encountered. The objective of the survey on the Lord Howe Island shelf (NSW) in 2008 (SS062008) was to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments and infauna, rock coring, observation of benthic habitats using underwater towed video, and measurement of ocean tides and wavegenerated currents. Subbottom profile data was also collected to map sediment thickness and shelf stratigraphy. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor. This dataset is published with the permission of the CEO, Geoscience Australia. Not to be used for navigational purposes.
