This is an article written as a contribution to the IEA GHG R&D Programme's quarterly newsletter (for publication in the June 2009 edition), at the invitation on the IEA GHG R&D Programme. It describes the release of Australia's offshore acreage for greenhouse gas storage.

This is the Acreage Release Marine Environmental Data compiled web service to be updated each year with acreage release. It contains the following publicly available datasets, for the 2016 Acreage Release - Marine Survey Towed-video Transects, Marine Sediments Database Samples, Australian Seascapes, Seabed Mud Content on the Northwest Shelf, Seabed Sand Content of the Northwest Shelf and Seabed Gravel Content of the Northwest Shelf.

The map contains greenhouse gas (GHG) data reported to Ecology as of December 15, 2018. The reported emissions are preliminary and have not been fully verified by Ecology. This information is subject to change. Certain large facilities and transportation fuel suppliers are required to report their greenhouse gas (GHG) emissions to Ecology beginning with the 2012 emissions year. Owners or operators of the following are required to report: • Facilities that emit at least 10,000 metric tons of carbon dioxide equivalent (CO2e) of greenhouse gases per year in Washington. • Suppliers of liquid motor vehicle fuel, special fuel, or aircraft fuel that supply products equivalent to at least 10,000 metric tons of carbon dioxide per year in Washington. These sources are not included on this map because they do not have a specific location. This dataset does not include all of Washington’s emissions. See the Washington State Greenhouse Gas Emissions Inventory (https://ecology.wa.gov/Research-Data/Scientific-reports/Statewide-greenhouse-gas-inventory) for statewide emissions totals. Emissions are in units of metric tons of carbon dioxide equivalents using AR4 global warming potentials as specified in WAC 173-441.

Geoscience Australia has the primary role in the delineation of Australia's domestic and international maritime limits and boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) data. AMB2020 is a GIS data product, replacing AMB2014a, providing access to the data for Australia's maritime zones. Offshore Petroleum and Greenhouse Storage Act 2006 - Australian Maritime Boundaries Dataset 2020 is a digital representation of the scheduled and offshore areas defined under this Act. In the event of an inconsistency between AMB data and the limits under any legislation, the latter prevails. The data have been published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office. The AMB2020 version has been updated to reflect the 2018 Timor Sea Treaty, including the Bayu-Undan Offshore Area. Offshore Petroleum and Greenhouse Storage Act 2006 - Australian Maritime Boundaries Dataset 2014 comprise the scheduled and offshore areas defined under the Act. AMB Data can also be viewed on-line via AMSIS (http://www.ga.gov.au/marine/jurisdiction/amsis.html). Product Specifications Coverage: Australia including all external territories Currency: August 2019. Coordinates: Geographical Datum: GDA94 (functionally equivalent to WGS84). Format: ESRI Geodatabase and REST web service - free online. The area of coverage of the AMB data is for the whole of the Australian marine jurisdiction which includes waters adjacent to the mainland, offshore islands and External Territories. The geographical extent is approximately between the latitude limits of 8 S to 70 S and the longitude limits 39 E to 174 E. This dataset includes the following disclaimers: AMB data is a digital representation of the territorial sea baseline and of the outer limits of Australia's maritime zones. The baseline and zones are established under the Offshore Petroleum and Greenhouse Storage Act 2006. In the event of an inconsistency between AMB data and the areas under the legislation, the latter prevails.

This dataset contains the 31 areas released as the 2013 Offshore Petroleum Acreage Release

The Western Australian Petroleum Releases (WAPRELEASE) digital data set contains any current Gazetted Petroleum release areas pertinent to the Offshore Petroleum and Greenhouse Gas Storage Act2006 (OPPGSA67), Petroleum Submerged Lands Act1982 (PSLA82) and Petroleum and Geothermal Energy Resources Act 1967 (PGERA67). This dataset was formally known as WA Petroleum Releases (DMP-015)

The regular release of offshore acreage is a key part of the Australian Government's strategy to encourage investment in petroleum exploration. This CD product contains six interactive 3D VRML models of the 2007 acreage release areas and was created for distribution at the 2007 APPEA conference and for later distribution via the web.
