Summary
[edit]| Description |
English: This flythrough highlights seabed environments within two areas of Arafura Marine Park offshore northern Australia; Money Shoal and Pillar Bank. Located 250 km to the northeast of Darwin within the Arafura Sea, the marine park extends to the limit of Australia’s exclusive economic zone, covering an area of 22,924 km2. Money Shoal is an isolated carbonate reef platform that rises from 70 m to shallow subtidal depths and supports a diverse coral and demersal fish community. The surrounding seabed comprises muddy substrate characterized by extensive fields of pockmark, interpreted as evidence for fluid escape from organic-rich sediment. Pillar Bank, in contrast, is representative of the deeper (150 – 200 m depths) outer shelf area of the marine park that supports sparse benthic communities of filter feeders on local outcrops of hard substrate, surrounded by expanses of muddy substrate. Demersal fish are also present, as observed using baited underwater cameras.
Bathymetry data and seafloor imagery for this flythrough was collected in November 2020 by Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS) on board RV Solander during survey SOL7491/GA0366. Funding was provided by the Australian Government’s National Environmental Science Program (NESP) Marine Biodiversity Hub, with co-investment by GA and AIMS.
