Marine Futures Project - Abrolhos Islands - reef habitat

The Marine Futures Project was designed to benchmark the current status of key Western Australian marine ecosystems, based on an improved understanding of the relationship between marine habitats, biodiversity and our use of these values. Approximately 1,500 km2 of seafloor were mapped using hydroacoustics (Reson 8101 Multibeam), and expected benthic habitats "ground-truthed" using towed video transects and baited remote underwater video systems. Both sources of information were then combined in a spatial predictive modelling framework to produce fine-scale habitat maps showing the extent of substrate types, biotic formations, etc.


Surveys took place across 9 study areas, including the Abrolhos Islands, a group of 122 limestone outcrops surrounded by fringing reed ca. 60km west from the city of Geraldton. The Abrolhos research location is the most northerly of the Marine Futures sampling sites, selected due to the unique mixture of tropical coral reef habitats, and temperate reef and seagrass communities.The hydroacoustics data were processed to construct full coverage maps of bathymetry and textural information.

Resource lineage

Statement
Areas of seafloor in water deeper than 10 metres were surveyed with hydroacoustics using a Reson 8101 Multibeam or interferometric swath echosounder system, mounted on the hull of the sampling vessel. These data were processed to construct full coverage maps of seafloor bathymetry and textural information. These maps, combined with observations recorded from in situ video footage, unerpinned the development of statistical models that produced the most efficient, objective, and ecologically meaningful classifications of sea floor features and inhabitants as possible for natural resource management and planning.
