This is a dataset of the world divided into 1° by 1° blocks, in the WGS84 datum. The blocks are organised and named using the International UTM Map Index and contain attribution concerning name, area and point of origin. The dataset is intended to assist with offshore fisheries, petroleum and minerals licensing by providing a regular graticulated system of blocks. The blocks were created using the same method as used for the Australian Offshore Minerals Blocks, and have used the same naming convention, which is derived from the map sheets. The blocks have been densified with a vertex added every 30 seconds to ensure they display correctly regardless of map projection.

A geodatabase depicting the International Map of the World numbering index as 1: 1,000,000 Universal Transverse Mercator (UTM) blocks with attribution.

This dataset includes point estimates of groundwater recharge in mm/year. Recharge rates have been estimated at monitoring bore locations in the basaltic aquifers of the Nulla and McBride basalt provinces. Recharge estimates have been calculated using the “chloride mass balance” method. The chloride mass balance process assumes that the chloride ion is a conservative tracer in precipitation, evapotranspiration, recharge and runoff; and that all the chloride is from rainfall, instead of for example halite saturation or dissolution processes. So the volumetric water balance and the flux of chloride balance must both be true. Assuming that runoff and evapotranspiration are negligible (so approximated by zero), the equation is simplified: Water balance P=ET+R+Q Water balance multiplied by chloride concentrations (chloridefluxbalance) P∙Cl_ppt=ET∙Cl_ET+R∙Cl_gw+Q∙Cl_riv | ΔCl_reac≈0 Assumptions to simplify equation P∙Cl_ppt=R∙Cl_gw | Q≈0 & ET≈0 Rearranging for recharge rate (unknown) R=P∙(Cl_ppt)/(Cl_gw ) | Q≈0 & ET≈0 Where P = precipitation rate; ET = evapotranspiration rate; R = recharge rate; Q = runoff to streams; Clppt = concentration of Cl in precipitation; ClET = concentration of chloride in evapotranspiration; Clgw = concentration of Cl in groundwater; Clriv = concentration of chloride in river runoff; ΔClreac = change in chloride concentrations from reactions.

This web service summarises salinity, water levels, resource size, potential aquifer yield and surface water–groundwater interactions for the Eromanga Basin located within the Galilee Basin region.

Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the north Bowen Basin. This web service summarises tight gas, shale resources and coal seam gas prospectivity of the north Bowen Basin.

The Seas and Submerged Lands Act (SSLA) 1973 is the Australian legislation that provides the domestic legal framework for Australia to declare its international offshore maritime zones, as provided for by the United Nations Convention on the Law of the Sea (UNCLOS) to which Australia is a party. Proclamations under the SSLA establish the territorial sea baseline, the territorial sea, the contiguous zone, the exclusive economic zone and the continental shelf. This service depicts official spatial representation of these proclamations. The service includes feature layers: Normal and Straight baselines limits and locations; Contiguous Zone and limit; Territorial Sea Zone and limit; Exclusive Economic Zone (EEZ), limits and locations; Continental Shelf limit and locations.
