The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

<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>

<div>The Varzin Passage to Merkara Shoal bathymetry survey was acquired for the Australian Hydrographic Office (AHO) during the period 4 Sep 2023 – 12 Apr 2024. This was a contracted survey conducted for the Australian Hydrographic Office by Fugro Australia as part of the Hydroscheme Industry Partnership Program. The survey area encompasses an area in Varzin Passage to Merkara Shoal. Bathymetry data was acquired using a LADS HD+, and processed using CARIS HIPS and SIPS, and QIMERA processing software. 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>

Processed seismic data (SEG-Y format) and TIFF images for the 2007 AuScope Deep Crustal Seismic Survey (L186), acquired by Geoscience Australia (GA) and funded by the Australian Government under the National Collaborative Research Infrastructure Strategy. Field logistics and processing were carried out by the Seismic Acquisition and Processing team from Geoscience Australia. Stack and migrated data for line 07GA-A1 as well as CDP coordinates. The seismic line is oriented approximately northeast-southwest and extends from near Mt Surprise in the southwest to near Mareeba in the northeast. Raw data for this survey are available on request from clientservices@ga.gov.au

Processed seismic data (SEG-Y format) and TIFF images for the Arrowie line acquired as part of the 2008 Curnamona-Gawler-Arrowie Deep Crustal Seismic Survey (L189), acquired by Geoscience Australia (GA) under the Onshore Energy Security Program (OESP). Stack and migrated data for line 08GA-A1 as well as CDP coordinates and gravity data. The Arrrowie line is 60km in length and was sited south of Lake Torrens and north of Port Augusta. Raw data for this survey are available on request from clientservices@ga.gov.au

Processed seismic data (SEG-Y format) and TIFF images for the Curnamona line acquired as part of the 2008 Curnamona-Gawler-Arrowie Deep Crustal Seismic Survey (L189), acquired by Geoscience Australia (GA) under the Onshore Energy Security Program (OESP). Stack and migrated data for line 08GA-C1 as well as CDP coordinates and gravity data. The Curnamona line is 262km in length and runs north-south, east of Lake Frome in South Australia.

Terracorp under its facilities management agreement with ANSIR was contracted to conduct the 1999 Yilgarn Seismic Survey located in the Kalgoorlie Goldfields region of Western Australia. In total 194.64 kms of 60 and 120 fold, 240 channel data was recorded between 19th August and 3rd September 1999. This high resolution and regional seismic profiles were acquired in order to image the major structural features of the region, particularly the highly mineralised Bardoc-Boorara Shear and to provide three-dimensional information about the relationship between the greenstones and the granites. Raw data for this survey are available on request from clientservices@ga.gov.au

Terracorp under its facilities management agreement with ANSIR was contracted to conduct the 1999 Lachlan and Marsden Seismic Surveys located around West Wyalong, NSW. In total 206.47 kms of 60, 80 and 120 fold, 160 & 240 channel data was recorded between 11th September 1999 and 29th September 1999. This Eastern Lachlan Orogen project was part of the research conducted by the Australian Geodynamics Cooperative Research Centre (AGCRC), which was established under the auspices of the Commonwealth Government's Cooperative Research Centres Program in 1993. The Ordovician volcanics and associated rocks of the Eastern Lachlan Orogen are important as a significant Australian gold province. To assist mineral exploration companies in understanding the geodynamics and mineral systems of this region, the AGCRC has been collecting information that will assist in the development of geodynamic and exploration models of the region. To understand the size and architecture of the mineral system, we need to know the threedimensional geometry of the system we are dealing with. To start to address this, in 1997 the AGCRC commenced a project in the Eastern Lachlan Orogen by collecting seismic information to examine the regional scale crustal architecture as a first step towards building exploration models for the region. We continued this work in 1999 with the collection of further deep seismic reflection data along two traverses in the Forbes-West Wyalong region. The northern traverse was jointly funded by the AGCRC and the Geological Survey of New South Wales (GSNSW) as a cooperative research project. The southern traverse was funded by the AGCRC, and co-investigators in the seismic interpretation involved staff from the AGCRC at AGSO, the GSNSW, and AGSO's Gilmore Project.

<p>In preparation for a National Geoscience Mapping Accord project involving a seismic survey planned for 1993, seismic tests were conducted on the Nullarbor Plain south of Cook to investigate the feasibility of imaging the sedimentary sequences and basement beneath the platform carbonates of the Eucla Basin, and to anticipate scientific and logistic difficulties associated with seismic acquisition on the Nullarbor Plain.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74950</b>

The data covers an area of approximately 4600 sq km in the Namoi Valley, located around Narrabri, NSW. The LiDAR was captured in September and October 2013 with a point density of two points per square metre. The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs, Canopy Height Models (CHM) and Foliage Cover Models (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF. The survey was conducted over two areas along the Namoi River: one from Boggabri to Narrabri, and the other between Wee Waa and Walgett including a newer extension to this original area to the north east of Wee Waa.
