Geoscience Australia (GA) brings capability and resources in marine geoscience and earth observation to the NESP Marine Biodiversity Hub with application to seabed mapping and benthic habitat modelling, ecosystem process modelling, geospatial analysis and prediction, mapping and change detection in coastal and shallow marine environments and web-based delivery of information to support evidence-based decision making. These capabilities can be applied, with co-investment from Geoscience Australia, across multiple projects and themes to deliver improved knowledge and understanding and enhanced collaboration and national capacity in marine science.
