    This dataset consist of dissolved oxygen (DO) and temperature data collected using HOBO Dissolved Oxygen loggers (U26-001) under FRDC project 2016-067. Loggers are deployed on strings in two locations in Macquarie Harbour, Tasmania.

  • Depth 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) depicting depth area polygons.

  • 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 record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Emerging Priorities project - "Spatial distribution of marine wildlife in the Bremer Bay region". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The Bremer Canyon system is a recognised aggregation area for marine wildlife and predictable aggregations of the orca (Orcinus orca) underpin local ecotourism. Additionally, the value of the region has been recognised in the establishment of the Bremer Commonwealth Marine Reserve (CMR) ( and the identification of the Albany canyon group and adjacent shelf break as a Key Ecological Feature in the South-West Marine Bioregional Plan (;jsessionid=01AD87551D0DE1B0248C8722BE137004). Little is known about the shelf and canyon region given its remote location and the relatively high cost of conducting offshore research. However, citizen-driven science has documented a stable aggregation of marine wildlife including orcas, sperm whales (Physeter microcephalus), and giant squid (Architeuthis sp.) occurring to the west of the established CMR. There is also speculation that this stable wildlife aggregation may be driven by seabed oil seeps with a hydrocarbon-based food chain although this is unsubstantiated. The potential uniqueness of this wildlife aggregation within the region and what drives its presence remains unknown. There is a significant need to determine the regional importance of this aggregation and its relation to the existing protection afforded by the Bremer CMR. The objective of this project is to improve the understanding of the importance of the Bremer CMR and surrounding region to marine wildlife. The project will determine the distribution of key wildlife of interest across the recognised pelagic aggregation and the Bremer CMR in order to inform Australian Government decision-making to protect the environment, conserve biodiversity and allow for sustainable use. The project will also improve understanding about the likely causes for wildlife aggregations and provide recommendations for future research options. Planned Outputs • A workshop of key experts, managers and external stakeholders to build on the literature review, identify additional data sources and recommend research priorities; • A workshop report including a literature review to synthesise existing information, data and publications on the region in relation to wildlife aggregations, general ecology, oceanography and productivity; • Marine wildlife survey – given the need to cover a large spatial area (i.e. the CMR and the known aggregation area in a single day), the preferred method is for an aerial survey with two observers. We propose that the team mobilises from Esperance given proximity to the CMR and ability to refuel etc. A team of two (2) scientific observers will be included plus an opportunity for an additional observer. The research will involve five (5) days of aerial surveying over no more than a seven (7) day period. The project will investigate the occurrence and distribution of orcas both inside and outside the known aggregation area (including the Bremer CMR). • Analysis of existing acoustic data – Curtin University holds data from acoustic surveys and will interpret these data in the context of distinguishing the presence and distribution of orcas, other cetaceans and other biota. • Analysis of existing orca distribution data within the aggregation – Curtin University has previously collected data on visual sightings of orcas at the aggregation. These data will be the spatial and temporal distribution of orcas at the aggregation site. This has the capacity to identify key patterns in orca behaviour within the known aggregation area. • Collation of orca observations held by ecotourism operator Naturaliste Charter – this collation will provide the opportunity to determine how best to use these data and generate communication products given the collection of imagery. • Pelagic fish survey – an existing planned survey to the Bremer CMR will be extended to include the aggregation area to allow the diversity, abundance and biomass of pelagic sharks and fishes in the CMR and the aggregation area to be compared. This will allow a comparison of the relative richness of the known aggregation area to the CMR with respect to pelagic shark and fish abundance. • Hydrocarbon signals in squid - Preliminary investigation into whether hydrocarbon signals can be detected in squid as a first step in determining whether the wildlife aggregation may be supported by hydrocarbon seeps. Murdoch University hold squid samples from the aggregation area that form the basis of this analysis. • Movement data to determine how adult orcas use the Bremer CMR and the aggregation area - tags will also be placed on at least three (3) adult orcas from the known aggregation site to clarify if those individual orcas are also transiting or using the Bremer CMR. • Knowledge exchange and communication outputs – each component of the project will produce materials for use by Parks Australia. Likely considerations are 3D fly-thru, animations, infographics, brochure, videos, articles. • Reporting outputs – a progress report focussing on completed field work and preliminary results will be produced followed by a final synthesis report.

  • The state boundary area of the Australia continental shelf (including Lord Howe Island). The coastline is at Lowest Astronomical Tide (LAT) and the shelf break is defined by the 200 m isobath taken from Geoscience Australia's GA 2009 bathymetric dataset.

  • This record relates to communications outputs of a research project which centered around working with Indigenous communities to raise the profile of the Largetooth Sawfish and support community driven conservation efforts. Some of the items are intended for public viewing (videos and educational signage); but the other outputs are intended for use by the Indigenous communities involved in the sampling (trip reports and Malak Malak annual floodplain sampling protocol and I-Tracker data collection application).

  • 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). The area defined at Lowest Astronomical Tide (LAT) by the Australian Hydrographic Office. The area of the Great Australian Bight (missing) in series, was replaced by Geoscience Australia's 1:100k coastline.

    Model output from a circumpolar realisation of the Regional Ocean Modelling System (ROMS). Model was run at a horizontal resolution of 1/4 degree and 31 vertical levels. Spatial domain was circumpolar out to 30 degrees South. Forcing comes from prescribed salt and heat fluxes based on a derived climatology from Tamura et al (2008). For open water regions the Tamura data is blended with open-water heat, salt and surface stress fluxes from a monthly NCEP2 climatology.

  • This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Emerging Priorities project - "Assessing the effectiveness of waste management in reducing the levels of plastics entering Australia’s marine environment". For specific data outputs from this project, please see child records associated with this metadata. -------------------- This project will contribute to better understanding where to target investment in abatement measures by providing information on the extent of the leakage of plastic materials into the marine environment, where the greatest leakages are and in what quantity, and what form they take (e.g. plastic bags, packaging, takeaway containers). It will also identify what type of facilities, policies and outreach strategies governments (state and local) have in place and undertake an assessment of their effectiveness. The objectives of this project are to: 1. Investigate the relationship between plastic debris in the marine environment and litter data from nearby sites; 2. Determine whether there are identifiable pathways through which plastic debris moves into the marine environment; 3. Investigate whether particular investments in facilities, policies or outreach are effective in reducing plastic debris on coasts and in oceans and where investment should be directed in the future; and 4. Initiate an internal department workshop to socialise the outcomes of the research across the relevant arms of the department, including staff involved in approvals, waste, protected species, and parks, and explore the utility of existing data to address the Department’s needs, including those arising from the TAP and the Senate Inquiry. Planned Outputs • A written report and plain English summary for use by state, territory and local governments, which: - Synthesises existing knowledge on the relationship between debris in the marine environment and litter data from nearby sites, the types of litter and the pathways through which litter moves into the marine environment. - Summarises existing coastal debris/litter survey methodologies with discussion of applications of each. • A list of the activities and programs associated with plastic waste reduction (including facilities, policies and outreach), • A publically accessible analysis and summary of different survey methods aiming to reduce debris inputs to the marine environment. - The cost of the activities and programs - Ranking of activities and programs regarding their effectiveness in reducing plastic waste in the marine environment. • Conclusions on where marine debris hot spots are in Australia’s marine environment and effective mitigation strategies. • Recommendations on where more information (scientific, policy, infrastructure, community engagement) is required to obtain a better understanding of the problem and possible solutions. This may include identifying knowledge gaps and needs for further analysis

  • This dataset provides predictions of pelagic vertebrate species richness and relative abundance throughout sub-areas of the Oceanic Shoals Australian Marine Park (AMP). Predictive models were constructed from in situ observations made using mid-water stereo-BRUVS (baited remote underwater video systems) deployed at 116 sites within three sampling areas in the western half of the AMP. Sampling took place in September and October 2012 aboard the RV Solander (survey GA0339/SOL5650), as part of an expedition supported by the National Environmental Research Programme's Marine Biodiversity Hub (Theme 3). Expedition partners included the Australian Institute of Marine Science (AIMS), Geoscience Australia (GA), The Centre for Marine Futures at the University of Western Australia (UWA), and the Northern Territory Museum.
