<div>The Abbot Point to Hydrographers Passage bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the RV Escape during the period 6 Oct 2020 – 16 Mar 2021. This was a contracted survey conducted for the Australian Hydrographic Office by iXblue Pty Ltd as part of the Hydroscheme Industry Partnership Program. The survey area encompases a section of Two-Way Route from Abbot Point through Hydrographers Passage QLD. Bathymetry data was acquired using a Kongsberg EM 2040, and processed using QPS QINSy. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.</div><div>This dataset is not to be used for navigational purposes.</div>

The Vlaming Sub-Basin CO2 Storage Potential Study web service includes the datasets associated with the study in the Vlaming Sub-basin, located within the southern Perth Basin about 30 km west of Perth. The data in this web service supports the results of the Geoscience Australia Record 2015/009 and appendices. The study provides an evaluation of the CO2 geological storage potential of the Vlaming Sub-basin and was part of the Australian Government's National Low Emission Coal Initiative.

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Logue Seismic, Gravity Lines - Perth Basin (P199461) contains a total of 342 point data values acquired at a spacing of 1000 metres. The data is located in WA and were acquired in 1994, under project No. 199461 for Geological Survey of Western Australia (GSWA).
