The Gippsland Basin is a premier hydrocarbon producing province, however exploration efforts in recent years were only met with limited success. New discoveries and extensions to existing ones were recorded along the northern basin flank, while the entire eastern, deeper water part of the basin remains underexplored to the present day. In order to address these questions Geoscience Australia has embarked on a petroleum systems modelling study to better understand the burial history of key horizons in the Gippsland Basin and its influence on changes in temperature, porosity, permeability and fluid migration.

International Quiet Days (IQD's) are the days where the geomagnetic variations are a minimum in each month. International Disturbed Days (IDD's) are 5 days in each month where the geomagnetic variations are maximum. The classification of days is relative only to the month of calculation. The average disturbance level in one month may differ from another.

The intended use for this application is to provide spatial discoverability for the Offshore well and seismic datasets within National Offshore Petroleum Information Management System (NOPIMS). This web service within this application is NOPIMS_Offshore_Well_and_Seismic_Discovery will also require to be made into a product. It will display the NOPIMS Offshore Well and Seismic surveys. The data does not provide the actually surveys only the spatial location of what survey can be requested. The wells layer consists of drilling surveys. The 2D seismic survey is conducted along lines and produces a single vertical profile. The 3D seismic survey is conducted over and area and produces a 3D subsurface model.

The GNSS database contains metadata and data quality statistics for continuous operating GNSS stations in Australia, its Territories and the South Pacific. GNSS stations consist of permanent geodetic quality GPS receivers, on geologically stable marks, with eight stations within Australia known as the Australian Fiducial Network (AFN) . These stations provide the geodetic framework for the spatial data infrastructure in Australia and its territories. They also provide input for the measurement of earth processes, such as crustal dynamics and sea level rise. Data from the GNSS network also contributes to the International GNSS Service . Where stations are managed by Geoscience Australia, Rinex data and quality statistics are available from this website.

Interactive application of Geoscience Australia's Australia through time poster, which gives a brief overview of Australia's geological history, featuring the geological timescale and paleogeograpgy of the continents.

The Australian Fiducial Network (AFN) consists of eight permanent, continuously operating, Geodetic GPS receivers on the Australian mainland and Tasmania. The network was initially observed during the International GPS Service for Geodynamics (IGS) Epoch '92 campaign, July-August, 1992. The AFN, in conjunction with additional sites beyond the Australian mainland, forms the Australian Regional GPS Network (ARGN).

Australian Regional GPS Network Updates Periodically, changes are made to the ARGN site's equipment or processes, to continually improve the system, to implement new technology, or to overcome problems. Where appropriate, these changes are reflected in the site logs. Also, while every endeavour is made to avoid them, occasionally there are delays or gaps in the data supply, due to circumstances beyond our control (such as floods, fires, mice plagues, lightning strikes and other minor incidents). When any significant events of this type occur, an Email is sent to everyone on the ARGN mailing list, giving the current status. If you wish to be notified of these events, please fill in the form below.

If you felt an earthquake, or know of an earthquake that occurred recently, please fill in this form. Even if you did not feel the earthquake yourself, please fill in the form, as this information will assist us.

This application allows the user to see a `real-time' representation of the Earth from a satellite that is currently orbiting our planet. The satellite database that provides the positioning information is updated regularly, but may not reflect the current position of satellites that manoeuvre frequently after reaching orbit.
