Survey InvestigatorDescription

John Keesing The Gascoyne region of Australia’s seafloor was identified for protection as an area of national significance and a new marine park (MP) was proclaimed in 2013 and the management plan came into force in 2018. The Gascoyne MP lies in an area with great but poorly known biological diversity and potential for economic development. The voyage will determine the diversity of fishes and of key habitat forming and mobile marine invertebrates across the range of depth regions and in each of the three zoning categories (IUCN II, IV, VI) in the MP. The data collected during the surveys will also provide descriptions of the physical and biological habitat types in the MP and will form the basis for future monitoring and reviews of marine park performance and zoning. The data obtained will likely refine the bioregionalization boundaries of the slope provinces and bathomes in the NW of Australia and resolve debate around the importance of the region from the point of view of the levels of endemicity of fishes and the voyage will also sample the very deep waters of the NW continental margin for the first time. A recent comparative study of the lower bathyal and abyssal depths on the eastern coastal of Australia and the Great Australian Bight found significant differences in assemblages between these locations. This study will enable a further comparison of these areas with the north-west of Australia at the same depths. In lay terms: This project will describe the habitats and quantify fish and seabed biodiversity of one of Australia’s newest marine parks which stretches from depths of less than 100 m to over 5000 m. The project is likely to discover new species of marine animals and ensure that conservation needs are more fully understood. This will identify and assist managers to maintain the park’s natural values into the future.
