  • 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. Planned Outputs • National Areas of Interest map • Code for Survey Coordination Tool • Value Prioritisation Framework [written report]

  • Flythrough movie of Gifford Marine Park, which is located 700 km east of Brisbane, Australia. The park is situated about halfway along the Lord Howe Rise seamount chain on the western flank of the Lord Howe Rise. Seamounts along this chain formed from Miocene volcanism via a migrating magma source (“hotspot”) after the opening of the Tasman Sea. Two large, flat-topped volcanic seamounts dominate the park. Their gently sloping summits have accumulated veneers of sediment, which in places have formed fields of bedforms. Steep cliffs, debris and large mass movement scars encircle each seamount, and contrast with the lower gradient abyssal plains from which they rise. Spanning over 3 km of ocean depths, the seamounts are likely to serve multiple and important roles as breeding locations, resting areas, navigational landmarks or supplementary feeding grounds for some cetaceans (e.g. humpback whales, sperm whales). They may also act as important aggregation points for other highly migratory pelagic species. The bathymetry shown here was collected on two surveys - the first in 2007 by Geoscience Australia and the second in 2017 by Geoscience Australia in collaboration with the Japan Agency for Marine-Earth Science and Technology. The Gifford Marine Park has also been the focus of a study undertaken by the Marine Biodiversity Hub as part of the National Environmental Science Program. This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

  • Bathymetry flythrough of Perth Canyon using data acquired by Schmidt Ocean Institute in 2015 on RV Falkor (University of Western Australia et al.). The flythrough highlights geomorphic features mapped by Geoscience Australia, including landslides, escarpments and bedform fields and biodiversity associated with the canyon (benthic and pelagic). Produced as a science communication product for the Marine Biodiversity Hub (National Environmental Science Program). This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

  • This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project D3 - "Implementing monitoring of AMPs and the status of marine biodiversity assets on the continental shelf". For specific data outputs from this project, please see child records associated with this metadata. -------------------- There is a significant need to support Parks Australia in the establishment of an inventory and monitoring program for Australian Marine Park (AMP) networks, and ensure it is integrated within broader national monitoring frameworks. The first part of this project provided a national collation all known mapping data from government and industry (including data acquired during CERF and NERP Hubs) to improve understanding of the distribution and extent of this key habitat around Australia, and to identify critical gaps in this knowledge to be filled by targeted surveys. This significantly improved understanding of KEF boundaries and conservation values or assets within Commonwealth Marine Reserves on Australia’s continental shelf. A classification system was developed for these reefs, and matched with refinement of inventory and monitoring approaches to track reef health through time, including standard approaches to SOE understanding and reporting consistent with measures developed for coastal systems within NESP (i.e. see project C2). This also involved collation of all mapping data on non-reef hard substrate, and all non-reef soft substrate, with this information also being available as a significant output. The second part of this project initiates a series of surveys, utilising standard operating procedures (SOPs), to demonstrate a sustainable path for a national survey program. By facilitating national approaches, including a standards-based approach to collecting new marine data, project outcomes will include key steps to assist Parks Australia to implement and initiate an AMP monitoring program, new knowledge to inform AMP management, a national integrated framework for State of Environment (SOE) reporting, and collaboration between State-based and Commonwealth-based programs. Planned Outputs • National-scale map of the distribution and extent of reef/non-reef habitat on the Aus continental shelf • Collation of all available mapping data for the Aus continental shelf • Detailed reports specific to each AMP survey, including a plain English summary • Survey data stored in national databases and portals • New multibeam mapping data from AMP survey areas and adjacent waters • New data on benthic invertebrate cover obtained from AUV imagery surveys • New data on benthic fish abundance obtained by BRUV surveys

  • Sediment organic carbon assessments within plots of transplanted Posidonia australis seagrass, and compared to adjacent bare sand and healthy meadows, in Shark Bay, WA.

  • Growth (shoot count) of Amphibolis antarctica and Posidonia australis following transplant to Middle Bluff and Dubaut Point, Shark Bay. Plants were transplanted by the Malgana people with assistance from UWA staff then assessed for shoot counts after 8 months.

  • Biodiversity assessments of invertebrates within seagrass (Amphibolis antarctica and Posidonia australis) transplant plots, compared to adjacent bare sand and healthy meadows at Middle Bluff, Dubaut Point and Useless Loop, Shark Bay.

  • Assessment of Posidonia australis transplant survival at 3, 8, 12, 18, and 26 months (August transplant); and 3, 8, 12, 18, 26 and 30 months (April transplant), after planting at Middle Bluff, and Dubaut Point, Shark Bay.

  • Genomic sampling locations and meadow indices for ribbon weed (Posidonia australis) and wire weed (Amphibolis antarctica) in Shark Bay (Gathaagudu)
