    Location of the new proposed Indigenous Protected Area (IPA) Tayaritja Milaythina Muka, the Sea Country around the Bass Strait Islands. The data was provided by the Tasmanian Aboriginal Centre and hosted by the Tasmania's Marine Atlas. The Tayaritja Milaythina Muka IPA project commenced in 2022 and involves the preparation of a management plan for the proposed IPA and has supported the establishment of the Pakana Sea Country Rangers and the purchase of assets to support Sea Country management. Later this year the management plan for the proposed Tayaritja Milaythina Muka IPA will be released for consideration by all relevant parties.

  • 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.

  • 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.

  • 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.

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

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

  • Trace element (TE) concentrations of juvenile Short-tailed Shearwaters collected on Great Dog Island, Tasmanian in 2017.

  • The Seamap Australia National Benthic Habitat Layer (NBHL) is a nationally synthesised database of seafloor habitat data, classified according to the Seamap Australia National Benthic Habitat Classification Scheme (https://vocabs.ardc.edu.au/viewById/129). In generating the Seamap Australia NBHL, datasets from data providers around Australia are collated and centrally hosted by IMAS (UTAS). Through time, some datasets become superseded by newer, more accurate data for the same region (improved data collection or processing methodology). This record aggregates all habitat datasets that have been collated as part of the Seamap Australia project, but are no longer considered the most accurate/up to date habitat for a particular region and have been superseded by another product. The parent record for the Seamap Australia NBHL provides an aggregation point for all "current" habitat datasets: https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/4739e4b0-4dba-4ec5-b658-02c09f27ab9a

  • NESP Marine Biodiversity Hub Project E7. Results from the outplanting of lab-selected and cultivated warm-adapted genotypes of giant kelp (Macrocystis pyrifera), at two trial restoration sites. A third restoration trial site had no surviving kelp, so those data were not included here. Data and details from lab-selection experiments can be found in the associated dataset - "NESP Marine Hub Project E7 - Macrocystis pyrifera thermal tolerance testing" https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/0b91d7fd-7d29-452f-954a-78cf75151035

  • The Seamap Australia spatial data layer is a nationally synthesised data product of seafloor marine habitat data. Australian continental shelf benthic habitat layers in GIS format were collected from various stakeholders around the country. Through compiling all of these data sets, we established a controlled vocabulary, reviewed by ANDS and external independent assessors, to produce a national classification of marine habitats. This national marine habitat classification scheme complements work undertaken by the National Environmental Science Program (NESP) Marine Biodiversity Hub (Theme D). The Seamap Australia product is of national importance and highlights the diversity of benthic habitats around our marine estate. This is the first edition of a seafloor marine habitat data layer that seamlessly brings together data from each of Australia’s state and territory marine habitat databases. Seamap Australia is a constantly evolving product as we continuously improve our skills in standardising, collating and sharing marine spatial data. This record describes a static version of the Seamap Australia national data layer as of 28/11/2018. The most current version of the data is available from the Seamap Australia website [http://seamapaustralia.org/map]. We envisage that the 'live' product will be constantly developed and updated as future surveys continue to improve our knowledge of our vast marine estate.
