The ETAS (Eastern TASmania) model is a high-resolution (~2 km in the horizontal) ocean model for eastern Tasmania, providing three-dimensional estimates of monthly mean temperature, salinity, and circulation over the 1993-2016 period. This dataset consists of temperature, salinity, meridional (N-S), zonal (E-W), vertical, along- and cross-shore currents, density, sea level and net surface heat flux organised into yearly files. A MATLAB script to extract portions of the data is available here: https://github.com/ecjoliver/extractETAS

Seabed areas were derived by aggregating and dissolving the boundaries of the 1 degree S57 file series for the Australian continental shelf and Lord Howe Island shelf (200 m). These areas were defined by the Australian Hydrographic Service (AHS).

This dataset has been superseded by https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/0145df96-3847-474b-8b63-a66f0e03ff54 (Victorian Statewide Marine Habitat Map 2023). The Victorian seabed habitat map documents the distribution of broad benthic habitat types in Victorian Coastal Waters to the State’s 3 nautical mile jurisdictional limit. The map was created using a top-down modelling process whereby habitat descriptors were assigned using seafloor structure and biological information derived from multibeam sonar (Victorian Marine Habitat Mapping Project), bathymetric LiDAR (Future Coasts program) and observations from underwater video. Identification of benthic biota, to the lowest discernible taxonomic level, and substrate characteristics were recorded according to the Victorian Towed Video Classification scheme (Ierodiaconou et al. 2007).

Land features were derived by aggregating and dissolving the boundaries of the 1 degree S57 file (lndare_a layer) series for the Australian continent (+ Lord Howe Island). This represents land the area defined at Lowest Astronomical Tide (LAT) by the Australian Hydrographic Office. The Great Australian Bight was missing from this series, and was replaced by Geoscience Australia's 1:100k coastline. This data has been made available through the data collation process conducted by the NESP Marine Biodiversity Hub Project D3 (Reefs on the Australian Continental Shelf).

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A12 - "Scoping a seascape approach to managing and recovering Northern Australian threatened and migratory marine species". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Northern Australia is the current focus of substantial economic development, which has the potential to impact biodiversity and cultural values. The Northern Seascape scoping project will assess the status of knowledge of EPBC-listed Threatened and Migratory Marine species, and pressures, Indigenous priorities, habitats, fisheries bycatch, and EPBC referrals in relation to them across the North Marine Bioregion (coast to EEZ edge). The focus will be at the multiple taxa level, including elasmobranchs, shorebirds, turtles and cetaceans. The project will scope research needs and directions for a broad Northern Seascape project (2018–2020), by identifying future research hotspots. Planned Outputs • Maps of Threatened and Migratory Marine species occurrence and habitats, and a gap analysis of research and data needs • Maps of state and trends in pressures and Threatened and Migratory Marine species, and the intersection between them • A report on Indigenous marine research and management priorities for Threatened and Migratory Marine species • Maps and time-series graphs that depict the extent and timing of past changes in coastal habitats that are important for TMM species • Identification of Threatened and Migratory Marine species bycatch and bycatch mitigation research priorities • Identification of EPBC referral spatial and species trends • Data, data visualisation and summaries available online through an appropriate web-based portal and/or existing internal DoEE information products • Project report synthesizing northern Australian Threatened and Migratory Marine species, pressures, Indigenous priorities, coastal habitat change, fisheries bycatch mitigation research priorities, and EPBC referral trends, and the identification of future research hotspots

Records of collisions between vessels and whales in Australian waters between 1872 and 2015 as described in the paper Peel, D., Smith, J. N., & Childerhouse, S. (2018). Vessel Strike of Whales in Australia: The Challenges of Analysis of Historical Incident Data. Frontiers in Marine Science, 5, 69.

Sea snake sightings from Baited Remote Underwater Video Stations deployed by the Australian Institute of Marine Science were used to predict locations that are likely important habitats for sea snake populations within the North West Marine Region (NWMR). Presence/Absence of sea snakes were modelled with environmental parameters using Gradient Boosted Regression Tree model to predict habitat suitability within the 1000 m depth contour along the NWMR. This output is a result of work conducted as part of the NESP Marine Hub Project A8- 'Exploring the status of Western Australia's sea snakes'.

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A11 - "Shark action plan". No datasets were generated by this project. -------------------- Conservation of elasmobranch species (sharks and rays) is an increasing priority globally, including Australia, as evidence of overexploitation of some species becomes apparent. Common issues and threats among elasmobranch species may improve management if considered holistically. This project will produce a Shark Action Plan assessing requirements for improved management including a summary of current status across the taxa, guidelines for reducing impacts and improving management, and identification of key knowledge gaps impeding conservation and management. This Plan will help guide policy for Australian elasmobranchs developed by DoEE and fishery managers. On-ground conservation will be developed from recommendations in this plan. Outputs • Shark Action Plan relevant to management of Australian elasmobranchs including an assessment of current threats, prioritised conservation and management actions for at-risk species and guidance on future management and data needs [written] • Manuscripts for scientific journals outlining the results of project components (eg, Conservation Dependent species framework) [written]
