  • The Joseph Bonaparte Gulf survey (SOL4934, GA survey #0322) was conducted on the R.V. Solander between 27 August and 24 September 2009 in collaboration with staff from the Australian Institute of Marine Science (AIMS) and the Northern Territory Government. The survey was completed under a Memorandum of Understanding between GA and the AIMS and represents the second of three surveys planned under this agreement. The survey obtained detailed geological (sedimentological, geochemical, geophysical) and biological data for the banks, channels and plains to establish the late-Quaternary evolution of the region and investigate relationships between the physical environment and associated biota for biodiversity prediction. Underwater video footage and still images were collected from 46 stations, although quality varies among transects and some still images were not of suitable quality for analysis. In addition, shipboard photographs were taken of barcoded biological specimens. Video and image files or associated parent folders are named according to station number, followed by gear code (TV or CAM = same underwater camera system) and then the deployment number. For example 48CAM35 represents a video transect from Station 48 that was the 35th video transect on the survey.

  • Geoscience Australia's World Wind Viewer is an application developed using NASA's World Wind Java Software Development Kit (SDK) to display Australia's continental data sets. The viewer allows you to compare national data sets such as the radioelements, the gravity and magnetic anomalies, and other mapping layers, and show the data draped over the Australian terrain in three dimensions.

  • The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium, uranium and thorium. The data are collected on airborne geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

  • Digital Elevation Model data record the terrain height variations from the processed point-located data recorded on an airborne geophysical survey.  The aircraft altimeter data records the height of the aircraft above the ground and the aircraft GPS records the height of the aircraft above the ellipsoid.  Subtracting the two values enables the height of the terrain beneath the aircraft relative to the ellipsoid to be calculated.  This ellipsoidal terrain height is corrected for the variation between the ellipsoid and the geoid (the n-value correction) to produce terrain heights relative to sea level.

  • Total magnetic intensity data measures variations in the intensity of the Earth's magnetic filed caused by the contrasting content of rock-forming minerals in the Earth's crust. The data are collected on airborne geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

  • Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data are collected on geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.
