The dataset indicates the long-term overall primary productivity hotspots of ocean surface waters. They are derived from MODIS (aqua) images using NASA's SeaDAS image processing software. The monthly chlorophyll a images between July 2002 and August 2014 are used to identify the overall primary productivity hotspots. The extent of the dataset covers the entire Australian EEZ and surrounding waters (including the southern ocean). The value (between 0 and 1.0) of the dataset represents the likelihood of the location being a primary productivity hotspot. This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.

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.

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A11 - "Shark action plan". -------------------- 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. Planned 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 • Integrated Conservation Advices for multiple species with similar threats • Significant Impact Guidelines for Australian elasmobranchs • Discussion paper outlining a framework for how to apply conservation strategies for fished (Conservation Dependent) species • Presentation of results to key stakeholders and end users • Manuscripts for scientific journals outlining the results of project components (eg, Conservation Dependent species framework)

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).

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.

This dataset relates to statistical models of killer whale (Orcinus orca) occurrence in the Bremer Sub-Basin developed from vessel-based and aerial survey data collected between 2015 and 2017.
