This record provides an overview of the NESP Marine and Coastal Hub bridging study - "Characterising values and identifying indicators and metrics of fish and benthic assemblages within the Capes region of the South-west Corner Marine Park". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Inventory surveys of Australian Marine Parks (AMPs) provide a broad description of the natural assets that exist in Commonwealth waters. These data can be further explored to identify biological indicators and metrics to cost-effectively monitor the AMPs and inform the AMP Monitoring Evaluation Reporting and Improvement (MERI) system. This project will use fish and seafloor imagery obtained from the recent inventory survey in the Capes region of the South-west Corner Marine Park to identify important natural values and indicators of fish and benthic assemblages relevant to park management and the AMP MERI system. Outputs • Habitat annotations to (1) AUV and (2) drop camera imagery following nationally agreed protocols (extended CATAMI classification - the Australian morphospecies catalogue) - to be published through the Understanding Marine Imagery (UMI) IMOS sub-facility • Bathymetry from National Park and Special Protection zones - published on AusSeabed • Geomorphic features map for existing fine scale bathymetry coverage of the National Park and Special Protection zones • Habitat map for existing fine scale bathymetry coverage (validated from from drop camera surveys for National Park and Special Protection zones • Fish and shark annotations of stereo-BRUVs • Science communication article for the Australian Marine Parks Science Atlas [written]

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "National Areas of Interest for Seabed Mapping, Characterisation and Biodiversity Assessment". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The project aims to assist the planning and prioritisation of marine surveys (both physical and biological) by scoping a prioritisation framework and web tool. Focused workshops and targeted engagements with seabed mapping organisations will ensure the framework meets the needs of the Marine and Coastal Hub, key end users such as Parks Australia, and the wider seabed mapping and biodiversity management community. Adoption and adaption of the AusSeabed Survey Coordination Tool will facilitate the development of an interim national areas of interest product to inform future survey planning. This product will support the needs of Parks Australia network Science Plans and consideration of information needs for Indigenous Protected Areas within Sea Country. Outputs • National Areas of Interest map • Code for Survey Coordination Tool [Github Repo] • Value Prioritisation Framework [written report]

Data represents marine bathymetry for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore (whichever boundary is first identified).

These data describe quantitative exposure indices generated using cartographic fetch methods on a 0.01 degree grid across temperate Australia (South Australia, Victoria and Tasmania). Two indices are reported: openness and bathymetry-altered fetch. Openness is a measure of the distance of a site to the nearest coastline in all directions and describes potential exposure to locally generated seas and undefined swell. Bathymetry-altered fetch attempts to account for the attenuation of wave energy as waves move into shallow waters and encounter friction with the seafloor.
