    We used data from satellite telemetry tags attached to six species of threatened and migratory marine megafauna across three taxonomic groups (marine turtles, whales and sharks) off the coast of north-western Australia to map their areas of use. We then compiled spatial data from a range of threats and overlayed species and threat maps to assess the level of exposure of the species to threats. In doing so we can identify areas where there is high exposure of species to threats, where risk assessments can be best directed with resulting management actions if needed in order to protect these species.

    We use genetics to estimate how far and wide oyster larvae can disperse to assist in setting biologically relevant spatial boundaries and harvest limits for oysters.

    To assist in recovery of the population, spatial areas of importance to pygmy blue whales, known as Biologically Important Areas (BIA), have been identified by the Australian Government. The AIMS team and collaborators Centre for Whale Research and Curtin University set out to reduce uncertainty in identifying where important foraging areas for this species and their migration pathways and distribution exist, and the extent to which they overlap with anthropogenic activities by deploying satellite tags.

    Key Ecological Features (KEFs) are parts of the marine ecosystem considered to be of particular importance for either a region's biodiversity or its ecosystem function and integrity. 13 KEFs have been defined for Australia’s North-west Marine Region, including the ‘Ancient Coastline at 125m depth contour’ (AC125). The AC125 is thought to “provide areas of hard substrate and therefore may provide sites for higher diversity and enhanced species richness relative to surrounding areas of predominantly soft sediment.” Little is known about what habitats exist on the sea floor in the AC125. Part of the reason is that the AC125 is very deep, and thus difficult to observe. The North West Shoals to Shore Research Program took underwater photographs and video of the seafloor to better understand each AC125 Area within its local context.

This dataset summarises benthic surveys in Marra Sea Country, including the Limmen Marine Park (Commonwealth) and Limmen Bight Marine Park (Northern Territory) into 4 GIS shapefiles.

This dataset consists of the historical range limits and poleward-most extent of recent extralimital occurrence of 82 potential marine species’ range extensions around Australia (NSW, QLD, SA, TAS, VIC and WA) revealed by an assessment of citizen scientists observations from Redmap, Reef Life Survey, and iNaturalist from 2013–2022.

This dataset shows the tiling grid and their Row and Path IDs for Landsat 4 - 9 satellite imagery. The IDs are useful for selecting imagery of an area of interest. Landsat 4 - 9 are a series of Earth observation satellites, part of the US Landsat program aimed at monitoring Earth's land surfaces since 1982.

This dataset consists of seagrass shoot height and biomass assessments from an experiment which compared control plots to exclusion cage plots which prevented megaherbivore grazing. This experiment ran at two sites from September 2021 to April 2022.
