Geomorphology - Lord Howe Island Shelf
Channel: GeoscienceAustralia
Date: 2014-10-01

Flythrough movie showing the bathymetry of the shelf surrounding Lord Howe Island, with examples of seabed habitats and biota. The bathymetric image is derived from merged grids, 8 m and 40 m resolution, that incorporates multibeam sonar collected in 2008 using a 30 kHz Simrad EM300 system on RV Southern Surveyor, legacy sonar data from various sources and satellite-derived bathymetry. Key features on the shelf bathymetry include a drowned reef that encircles the island and intervening areas of sediment-covered basins. Lord Howe Island shelf is a study site for the Marine Biodiversity Research Hub, funded through the Commonwealth Environment Research Facilities programme.
