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.

This service has been created specifically for display in the National Map and the symbology displayed may not suit other mapping applications. Information included within the service includes the point locations for surface hydrology, including natural and man-made features such as water courses (including directional flow paths), lakes, dams and other water bodies and marine themes. The data is sourced from Geoscience Australia 250K Topographic data and Surface Hydrology data. The service contains layer scale dependencies.

Eddy Covariance (EC) has been proposed as a surface monitoring solution for long-term deployment at CCS sites. However, its suitability when applied to a highly inhomogeneous source area- as would be the case for a small-scale CO2 surface leak- has been poorly established. For this reason, EC has been implemented for two controlled CO2 releases conducted at the Ginninderra controlled release facility, with the aim of determining the technique's suitability for the location, detection and quantification of a small magnitude CO2 leak (144 kg/d). By comparing results from the two release experiments, this poster highlights the variable success of using EC for detection, and how this may depend on changing experimental and climatic variables such as leak location, tower height and depth to groundwater. The detection significance of grouped EC measurements will be established through statistical analysis using Cramer-Von Mises tests. In addition, the application of two EC towers concurrently for leak detection and location will be explored, with a second tower deployed for the latter portion of the 2013 release experiment. Quantification of the leak using EC was attempted, but due to the problems in the fundamental assumptions of the technique, no substantive progress could be made. This will be explained with respect to the 'lost' CO2 from the system in part due to advection and diffusion. Presented at the 2014 CO2CRC Research Symposium

<div>The aim of the Interferometric Synthetic Aperture Radar (InSAR) project is to develop an end-to-end, fully automated InSAR processing system that will take raw SAR data from any sensor and produce time-series maps of surface deformation/movement.</div><div>Surface deformation maps are important products to help define the national geodetic reference frame by augmenting the geodetic data obtained from sparse ground networks, in addition to identifying regions with elevated natural hazard risk.</div>

<p>This data release is part of the Federal Government’s Exploring for the Future program undertake by Geoscience Australia in collaboration with the Northern Territory Geological Survey and the Geological Survey of Queensland. It is the second staged release of data from the North Australian Geochemical Survey which sampled catchment outlet sediments at 780 sites (including duplicates) for geochemical analysis. </p> <p>The survey area was chosen to encompass the preeminent mineral provinces of Tennant Creek and Mt Isa, with the region between these two provinces providing a vast prospective exploration frontier, covered by a thin veneer of sediments and basalts, which has been overlooked for mineral exploration in the past. The data are not only useful for mineral exploration but also for agriculture and environmental management. For agriculture, this dataset can be used to assess soil fertility to maintain sustainable crop production and inform cattle grazing management over such areas as the Barkly Tablelands. The survey establishes a robust geochemical baseline dataset relevant to many environmental issues which can be utilised in development decision making into the future.</p> <p>This data release includes (1) results of the total chemical analyses of the coarse (<2 mm) fraction of sampled sediments (XRF, ICP-MS), (2) results of the aqua regia analyses of the coarse and fine fractions (<2 mm and <75 µm, respectively), and (3) results of the fire assay analysis of the coarse and fine fractions. Included is a set of georeferenced digital images of geochemical maps based on this dataset.</p>
