AUSGeoid98 v.1.0 data files:  (sj56-13)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Characterising the impact of tropical cyclones on mangroves using a multi-decadal Landsat archive

Tropical cyclones can significantly impact mangrove forests, with some recovering rapidly, whilst others may change permanently.  Inconsistent approaches to quantifying these impacts limit the capacity to identify patterns of damage and recovery across landscapes and cyclone categories. Understanding these patterns is critical as the changing frequency and intensity of cyclones and compounding effects of climate change, particularly sea-level rise, threaten mangroves and their ecosystem services. Improvements in Earth observation data, particularly satellite-based sensors and datacube environments, have enhanced capacity to classify time-series data and advanced landscape monitoring. Using the Landsat archive within Digital Earth Australia to monitor annual changes in canopy cover and extent, this study aims to quantify and classify immediate and long-term impacts of category 3–5 cyclones for mangroves in Australia. Closed canopy mangrove forests experienced the greatest immediate impact (loss of canopy cover).Most immediate impacts were minor, implying limited immediate mortality. Impacts varied spatially, reflecting proximity to exposed coastlines, cyclone track and forest structure (height, density, condition and species). Recovery was evident across all cyclones, although some areas exhibited permanent damage. Understanding the impacts and characteristics of vulnerable and resilient forests is crucial for managers tasked with protecting mangroves and their services as the climate changes.

The Granites, Mt Solitaire, Highland Rocks, Mt Theo, NT, 1993 (P599), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the The Granites, Mt Solitaire, Highland Rocks, Mt Theo, NT, 1993 survey were acquired in 1993 by the NT Government, and consisted of 108984 line-kilometres of data at 500m line spacing and 90m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Geological Insights from the Search for Malaysian Airlines flight MH370

A rich trove of marine geophysical data acquired in the search for missing flight MH370 is yielding knowledge of ocean floor processes at a level of detail rare in the deep ocean.
The tragic disappearance of Malaysian Airlines flight MH370 on 8 March 2014 has led to a deep ocean search effort of unprecedented scale and detail. Between June 2014 and June 2016, state-of-the-art shipboard multibeam echosounder (MBES) and sub-bottom profile data were collected in a ~255,000 km2 zone of the southeastern Indian Ocean. The arcuate, NE-SW oriented search swath (75 to 160 km wide) centers on Broken Ridge and extends ~2500 km from the eastern flank of Batavia Seamount to the Geelvinck Fracture Zone (Figure 1). Aircraft debris found along the shores of the western Indian Ocean is consistent with drift modelling that indicates an origin in the search area (https://www.atsb.gov.au/mh370/). The resultant dataset constitutes the largest MBES mapping effort for the Indian Ocean, representing about half the size of California, improving spatial resolution of the ocean floor in this region from an average of &gt;5 km2 to &lt;0.1 km2. Importantly, the new data provide the geospatial framework for the current phase of the search – deployment of deep-water, high-resolution acoustic and optical imaging instruments able to identify aircraft wreckage.

Detailed Assessment of the Korumburra Earthquake Cluster, 2009

On March 6, 2009 a magnitude 4.6 earthquake occurred near Korumburra in southeast
Victoria. This event was followed by a series of earthquakes lasting for several
months. In the days following this earthquake six temporary high-sample rate seismic
recorders were deployed in the epicentral region by Geoscience Australia (GA),
Environmental Systems and Services (ES&amp;S) and Gary Gibson. These instruments
complemented the permanent networks operated by GA and ES&amp;S, and captured a
second large shock on March 18 also measuring 4.6 and many smaller aftershocks.

The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This radiometric uranium grid has a cell size of 0.00063 degrees (approximately 66m) and shows uranium element concentration of the Robert merge, 1991-1998 in units of parts per million (or ppm).

The Geoscience Australia Laboratory - today's quality is tomorrow's reputation

In geoscience we often use ‘quality’ to describe our activities and products, but what does ‘quality’ actually look like? How do we measure it and determine if something is the ‘quality’ facility or ‘quality’ data we say it is? This is not simply an esoteric thought experiment – it matters: end-users and stakeholders are already making decisions potentially affecting whole communities and worth millions of dollars based on their understanding of the quality of our geochemical analytical data. These products are the foundation of Geoscience Australia’s reputation as a trusted advisor to government, communities and industry. 
This talk will guide you through the Geoscience Australia Laboratory, paying particular focus to our role in quality control and assurance for a range of analytical data products, including our core analytical capabilities in Organic Geochemistry, Microanalysis and Physical Properties. You will hear how the labs are evolving as we build new facilities and build on our capabilities. You will learn more about the importance of quality, how it is defined and some tools to apply in your own work.
