These datasets represent locations of offshore seismic surveys and data collection points. Four datasets make up this set : A dataset showing the navigation tracks of marine deep seismic lines from RV Rig Seismic. A dataset showing locations of offshore refraction shot points. A dataset showing locations of seismic recording stations. A dataset showing locations of sonobouy stations. These datasets are generated from a database containing coordinates of all of seismic traverses.

Community risk within the local government authority is investigated for: tropical cyclones and storm tide, east coast lows, thunderstorms, tropical cyclones and severe wind, flood, earthquake, landslide, heat wave and bushfire. Magnitude/returne period scenarios are developed and impact on communities investigated.

These datasets represent locations of onshore seismic surveys and data collection points on the Australian continent. Four datasets make up this set : A dataset showing onshore deep seismic traverses since 1974. Selected scanned seismic sections (GIF format) from most of the seismic surveys are also available. A dataset showing locations of onshore refraction shot points. A dataset showing locations of seismic recording stations. A dataset showing where has completed deep seismic soundings in Australia. These datasets are generated from a database containing coordinates of all seismic traverses.

The Davis Coastal Seabed Mapping Survey, Antarctica (GA-4301 / AAS2201 / HI468) was conducted on the Australian Antarctic Division workboat Howard Burton during February-March 2010 as a component of Australian Antarctic Science (AAS) Project 2201 - Natural Variability and Human Induced Change on Antarctic Nearshore Marine Benthic Communities. The survey was undertaken as a collaboration between Geoscience Australia, the Australian Antarctic Division and the Australian Hydrographic Service (Royal Australian Navy). The survey acquired multibeam bathymetry and backscatter datasets from the nearshore region of the Vestfold Hills around Davis Station, Antarctica. This dataset comprises an interpreted geomorphic map produced for the central survey area using multibeam bathymetry and backscatter grids and their derivatives (e.g. slope, contours). Six geomorphic units; basin, valley, embayment, pediment, bedrock outcrop and scarp were identified and mapped using definitions suitable for interpretation at the local scale (nominally 1:10 000). Polygons were created using a combination of automatic extraction and manual digitisation in ArcGIS. For further information on the geomorphic mapping methods and a description of each unit, please refer to OBrien P.E., Smith J., Stark J.S., Johnstone G., Riddle M., Franklin D. (2015) Submarine geomorphology and sea floor processes along the coast of Vestfold Hills, East Antarctica, from multibeam bathymetry and video data. Antarctic Science 27:566-586.

Two maps have been updated for RET to include in a Ministerial Breifing on the Northern Territory conferral to NOPSEMA for regulation of offshore petroleum activities in their designated coastal waters. The updates reflect the amended OPGGS Act definition of designated coastal waters. These maps relate to Geocat 81958. Not for public release. RET internal use only.
