Geoscience Australia carried out a marine survey on Carnarvon shelf (WA) in 2008 (SOL4769) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wavegenerated currents. Data and samples were acquired using the Australian Institute of Marine Science (AIMS) Research Vessel Solander. Bathymetric mapping, sampling and video transects were completed in three survey areas that extended seaward from Ningaloo Reef to the shelf edge, including: Mandu Creek (80 sq km); Point Cloates (281 sq km), and; Gnaraloo (321 sq km). Additional bathymetric mapping (but no sampling or video) was completed between Mandu creek and Point Cloates, covering 277 sq km and north of Mandu Creek, covering 79 sq km. Two oceanographic moorings were deployed in the Point Cloates survey area. The survey also mapped and sampled an area to the northeast of the Muiron Islands covering 52 sq km. cloates_3m is an ArcINFO grid of Point Cloates of Carnarvon Shelf survey area produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software

This is a polygon file, one of five within the Rockhampton Regional Council coastline, which buffers the coastline by 4 km inland. This extent was use to clip the storm tide inundation extents and to visualise each of the five distinct inundation zones.

This report presents new SHRIMP U-Pb zircon results for fifteen samples from the New England region of New South Wales (Fig. i and Table i). The work was carried out under the auspices of the National Geoscience Agreement (NGA) between Geoscience Australia and the Geological Survey of New South Wales. The data and age interpretations contained in this report are available in Geoscience Australia's Geochron Delivery database (http://www.ga.gov.au/geochron-sapub-web/). Summary of results and significance: 1. The 'coastal granitoids' occurring to the east of the main geographically continuous axis of granites in the central portion of the batholith range in age from 238 Ma for Round Mountain Leucoadamellite; ~230 Ma for the Yarrahapinni Granite and Valla Adamellite; ~220 Ma for Glen Esk Adamellite and Smokey Cape Adamellite; to 212 Ma for the Middle Brother Monzodiorite. Granitoid magmatism in this region has not occurred in a single early Triassic flourish, but episodically, and generally younging eastwards to the coast. 2. Leucoadamellites previously considered to be 'Triassic' (i.e. younger than the main stage of the batholith), have been shown to be older. These units - the Oban River Leucoadamellite (252 Ma) and Red Range Leucoadamellite (253 Ma) - are the same age as the major units of the Moonbi and Uralla supersuites. 3. The Mount Duval Monzogranite and Newholme Monzogranite are indistinguishable in age. The Newholme Monzogranite was recognised as a discrete unit in the Mount Duval pluton on the basis of geophysics, petrography and geochemistry. 4. The Highlands Complex, though petrographically and geochemically distinct from most other magmatism in the New England Batholith is the same age as the main magmatic stages of the Moonbi and Uralla Supersuites. 5. The Emmaville Volcanics in the Yarraford area, near to the Glen Eden porphyry tin deposit is the same age as other members of the Wandsworth Volcanic Group and the main magmatic stage (252 Ma) of the batholith. The mineralisation at Glen Eden, which is partially hosted by the volcanics, is Triassic in age, although anomalously old Re-Os ages have been determined from molybdenite within the deposits. 6. Elsmore Granite age at 250 Ma is close to in age, but just younger than that of the adjacent tin mineralised Gilgai Granite. The Elsmore Granite forms a distinct satellite intrusion to the Gilgai Granite. 7. The Culaden Granodiorite (informal) is one of a number of small porphyritic granodiorite stocks and dykes in the Emmaville-Tent-Hill-Ottery area. The 252 Ma age indicates they are not contemporaneous with the Mole Granite and predate tin mineralisation in the area. They are essentially the same age as the Wandsworth Volcanic Group. 8. The tin mineralised Pringles Monzogranite in the Watson Creek area near Bendemeer is shown to be 289 Ma, indistinguishable in age from the host Bundarra Supersuite, indicating that the intrusion and its attendant tin mineralisation is not related to younger magmatism elsewhere within the batholith.

This Record presents new zircon U Pb geochronological data obtained via Sensitive High Resolution Ion Micro Probe (SHRIMP) from rocks sampled within the Wau 1:100 000 map sheet area, which is located on the Papuan Peninsula in eastern Papua New Guinea. Exposure in the Wau Bulolo region comprises low-grade Mesozoic metasedimentary rocks of the Owen Stanley Metamorphics, which are intruded by the mid-Miocene Morobe Granodiorite batholith, and overlain by Pliocene sedimentary and volcanic rocks of the Wau Basin. The map sheet area contains the Morobe Goldfield (from which more than 3.2 Moz of alluvial gold has been mined) and the Hidden Valley epithermal Au-Ag deposit (which has a total gold resource in excess of 3 Moz), and lies about 70 km south-southeast of the giant mid-Miocene Wafi-Golpu porphyry Cu-Au deposit (>26 Moz Au and 9 Mt Cu). The geochronological data in this Record were generated as part of a collaborative project between Geoscience Australia (GA) and the Mineral Resources Authority (MRA) of Papua New Guinea in 2012. Four samples were analysed: two from the Pliocene Bulolo Volcanics and one from the Miocene Morobe Granodiorite to establish precise, accurate magmatic crystallisation ages, and one metasandstone from the Mesozoic Owen Stanley Metamorphics for detrital zircon provenance analysis. Sample locations, descriptions, and U Pb SHRIMP results are summarised in Table 1.1.

Fresh groundwater stored in Australian coastal aquifers constitutes an important resource for humans and the natural environment. However, many Australian coastal aquifers are vulnerable to seawater intrusion (SWI) - the landward encroachment of seawater into coastal aquifers. SWI can significantly degrade water quality and reduce freshwater availability. In response to the threat posed by SWI, Geoscience Australia (GA) and the National Centre for Groundwater Research and Training (NCGRT), in collaboration with state and territory water agencies, have undertaken a national scale assessment of the vulnerability of coastal aquifers to SWI. This assessment aims to identify the coastal groundwater resources that are most vulnerable to SWI and considers the future consequences of over-extraction, sea-level rise, and recharge-discharge variations associated with climate change. In order to achieve the project aims, the study comprised five technical assessments to analyse factors contributing to the vulnerability of coastal aquifers: (i) vulnerability factor analysis (VFA); (ii) coastal aquifer typology; (iii) mathematical analysis; (iv) SWI quantitative and qualitative vulnerability indexing; and, (v) future land surface inundation and population growth analysis. This report covers the VFA component of the project which provides a first-pass, regional assessment of SWI vulnerability indicators in Australia's coastal areas based on state and territory groundwater datasets for individual groundwater bores. A large number of measurements were collated for this project. In total, more than 1.7 million groundwater levels and more than 1.1 million salinity measurements were compiled and evaluated.
