Seabird and marine mammal tracking data from the Tasman Fracture Marine Park

Biotelemetry devices, including satellite transmitters and archival Global Positioning System (GPS) loggers, were deployed on shy albatrosses, short-tailed shearwaters, and both Australian and long-nosed fur seals. Tags were deployed during the breeding season to maximise data on foraging behaviour and habitat use. This record currently contains tracking data from breeding adult shy albatross (Thalassarche cauta). Additional tracking data from migratory short-tailed shearwater (Ardenna tenuirostris), the endemic Australian fur seal (Arctocephalus pusillus doriferus), and long-nosed fur seal (Arctocephalus forsteri) will be added at a later date. The shy albatross collection includes raw tracking data, and filtered processed tracks fitted with a state space model (Jonsen et al., 2023). These data include the following variables: birdID, breeding phase, tracker type, date/time, locations in latitude and longitude (for both the raw and fitted), and uncertainty metrics. ***EMBARGO NOTE*** Data is currently embargoed - to be released late 2026.

Collated data inventory for Shy Albatross in relation to the Gippsland Offshore Renewable Energy declaration area (NESP MaC 3.21)

This project undertook a rapid exploration of information on a priority subset of species identified by the Department of Climate Change, Energy, the Environment and Water (DCCEEW) and the National Offshore Petroleum Safety and Environment Authority (NOPSEMA) that are listed as critically endangered or endangered under the Environment Protection and Biodiversity Conservation Act 1999. It specifically focused on these species in relation to the Gippsland declaration area, and the adjacent areas to the declaration area in Bass Strait. This rapid exploration of information was conducted as follows: 1) identify datasets and information sources relevant to priority species identified by DCCEEW and NOPSEMA for the Gippsland declaration area; 2) identify the source of these datasets and information and their level of accessibility; 3) evaluate the utility of datasets and information identified in 2) for assessments/regulatory processes required to be undertaken by DCCEEW and NOPSEMA; and 4) identify what activities would need to be undertaken to improve the accessibility and utility of datasets and information sources identified in 3) that are not currently accessible in useable formats. Fifteen priorities species (12 birds, 3 cetaceans) were identified for which publicly-available occurrence data could be located. This record and the attached download describes the data inventory for Shy Albatross (Thalassarche cauta).

A multidisciplinary study of the Tasman Fracture Marine Park pelagic ecosystem

The Tasman Fracture Marine Park (TFMP), located off the southwestern coast of Tasmania, is an ecologically and culturally significant area characterised by dynamic and diverse marine ecosystems ranging from abyssal plains to rocky reefs. This region is a productivity hotspot due to the convergence of ocean currents and upwelling processes (Ridgway and Ling, 2023), which supports rich biodiversity, including endangered species such as the shy albatross (Thalassarche cauta), the migratory short-tailed shearwater (Ardenna tenuirostris), the endemic Australian fur seal (Arctocephalus pusillus doriferus) and expanding populations of long-nosed fur seal (Arctocephalus forsteri). The primary objectives of this multidisciplinary research were to quantify the physical water properties within the TFMP to establish baseline environmental conditions; map mesopelagic (midwater) productivity using acoustic equipment; characterise the foraging behaviour and habitat use of key marine predators through biotelemetry devices; investigate the diet of seabird and fur seal species to understand pelagic food web interactions; and assess cetacean species diversity, temporal patterns, and quantify underwater noise using passive acoustic monitoring. To achieve these objectives, the study employed a combination of methodologies (see 'Lineage' section for full methodology): • Oceanographic analysis provided insights into the climatology and productivity patterns influenced by the East Australian Current and the Zeehan Current. • Biotelemetry tracking of seabirds and seals provided data on foraging behaviour and habitat use of key predators. • Scat sampling of predator species combined with DNA metabarcoding techniques were utilised to identify prey species and provide detailed dietary profiles. • Underwater acoustic recorders were used to monitor cetacean vocalisations and assess underwater noise levels. In summary, this research provides essential baseline data and insights into the complex interactions within the TFMP's ecosystems. The findings emphasise the need for integrated, multidisciplinary approaches to marine conservation. By addressing the identified challenges and implementing the recommendations, managers can enhance the resilience of the TFMP, ensuring the protection of its unique biodiversity in the face of environmental changes.
