<div>This dataset was produced under Stream 1 - Work Package 4 of the 2021-23 Australian Research Data Commons (ARDC) Bushfire Data Challenge Project; a collaborative partnership between the ARDC, Geoscience Australia, and the Emergency Management Spatial Information Network. The Project’s aim was to bring together a single nationally consistent and harmonised historical bushfire boundary data derived from the authoritative state and territory agencies. Geoscience Australia's role within this project was to; negotiate access to the data, collate and transform the data into the National Standard and then deliver the 'Historical Bushfire Boundaries' data through a static file and a webservice.</div><div><br></div><div>More information about the ARDC Project and Work Package 4: <br>https://ardc.edu.au/program/bushfire-data-challenges/</div><div> More information about the Fire History Data Dictionary: <br>https://www.afac.com.au/insight/doctrine/article/current/fire-history-data-dictionary</div><div><br></div><div>The Historical Bushfire Boundaries dataset represents the aggregation of jurisdictional supplied burnt areas polygons stemming from the early 1900's through to 2022 (excluding the Northern Territory).

The Great North Channel Torres Strait Multibeam survey was acquired for the Australian Hydrographic Office (AHO) onboard the MV Offshore Guardian and MV Special Order during the period 04 February– 14 April 2021. This was a contracted survey conducted by Guardian Geomatics as part of the Hydroscheme Industry Partnership Program. The survey area encompasses the Great North East Channel of the Torres Strait located between the Stephens Island, Pearce Cay and Rennel Island, Queensland. Bathymetry data was acquired using a Kongsberg EM2040-07 and Norbit iWBMSh Stx 200-400 kHz and processed using CARIS HIPS & SIPS 11.3 processing software. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area. <BR>This dataset is not to be used for navigational purposes.

The Northern Approaches to Broome multibeam survey was acquired for the Australian Hydrographic Office (AHO) onboard the MV Bhagwan K during the period 05 August– 02 October 2020. This was a contracted survey conducted by EGS as part of the Hydroscheme Industry Partnership Program. The survey area encompasses the northern approaches to Broome, WA located between the Talboys Rock and Gantheaume Point, Western Australia. Bathymetry data was acquired using a Kongsberg EM2040D 200-400 kHz and processed using QPS QINSy 9.2.3 processing software. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area. <BR>This dataset is not to be used for navigational purposes.

Under the Federal Governments’ Exploring for the Future (EFTF) program, Geoscience Australia (GA) recently acquired the Barkly and South Nicholson deep-crustal seismic reflection surveys (L212 and L210, respectively) in partnership with the Northern Territory Geological Survey (NTGS) and Geological Survey of Queensland (GSQ). The Barkly survey was completed in late 2019 as a collaboration between GA’s EFTF program and NTGS’s Resourcing the Territory initiative. Acquisition started at the Queensland-Northern Territory border near the town of Camooweal. It is comprised of five lines; 19GA-B1 (434.6 km), 19GA-B2 (45.9 km), 19GA-B3 (66.9 km), 19GA-B4 (225.8 km), and 19GA-B5 (39.4 km) (Southby et al., 2021), and was acquired via vibroseis using a nodal geophone system (Fomin et al., 2020), and links into the South Nicholson survey acquired in 2017. In 2019, the Camooweal deep-crustal seismic reflection survey (GSQ Open Data Portal 95590) was acquired by the GSQ as part of the Queensland Government's Strategic Resources Exploration Program (SREP), and was centred on the northwest Queensland town of Camooweal with the total length of acquisition spread over three lines; 19Q-C1 (65.8 km), 19Q-C2 (173.6 km) and 19Q-C3 (60.9 km). The Camooweal survey was acquired via vibroseis using a nodal geophone system and links to the South Nicholson and Barkly surveys (Edwards, 2020). These seismic surveys have improved our understanding of the basins, basement structures and structural evolution of the region. They tie the underexplored region with the more explored and highly prospective McArthur and Mount Isa Province, in which there are now new areas identified for future exploration. The known, mappable extent of the South Nicholson Basin has been increased significantly and a new, potentially Proterozoic age, depocentre, the Carrara Sub-basin, located in the south east of South Nicholson region, has been discovered (Henson et al., 2018; Carr et al., 2019; Carson et al., 2020; MacFarlane et al., 2020). The Carrara Sub-basin is interpreted to include strata equivalent in age to the Isa Superbasin, South Nicholson Group, and the Georgina Basin (Carr et al., 2020) and current work on the NDI Carrara 1 drill hole will further constrain the stratigraphy and geology of the South Nicholson region; providing well control to the extensive network of new deep-crustal seismic acquired in this highly prospective frontier province. The aim of this study is to show the extent of the Carrara Sub-basin sedimentary packages by mapping the lateral extent of sedimentary sequences using seismic data interpretation.
