The Search for Flight MH370 - Phase 2 Raw and Processed Data

On behalf of Australia, and in support of the Malaysian accident investigation, the Australian Transport Safety Bureau (ATSB) led search operations for missing Malaysian Airlines flight MH370 in the Southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB to facilitate marine surveys, which were undertaken to provide a detailed map of the sea floor topography to aid navigation during the underwater search. Prior to the Phase 1 bathymetric survey, very little was known about the sea floor in the MH370 search area, as few marine surveys have taken place in the area. Existing maps of the sea floor were coarse, having been derived from satellites and only providing a general indication of water depth. Before the underwater search for MH370 could begin, it was necessary to accurately map the sea floor to ensure that the search was undertaken safely and effectively. Survey vessels spent months at sea, scanning the sea floor with multibeam sonar and side scan sonar to gather detailed, high-resolution data.
This collation of datasets contains the high resolution raw and processed data acquired during Phase 2 of the search for MH370 as received by third party operators. The Phase 2 underwater search data was acquired by multiple vessels, including the Fugro Equator, Fugro Supporter, Fugro Discovery, Havila Harmony, Dong Hai Jiu 101 and Go Phoenix. Surveys were conducted using towed and autonomous underwater vehicles between September 2014 to January 2017, collecting over 121,000 square kilometres of high resolution data in the search area.

Billabong Creek doserate grid geodetic

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 (K), uranium (U) and thorium (Th). 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Billabong Creek doserate grid geodetic has a cell size of 0.00021 degrees (approximately 21m) and shows the terrestrial dose rate of the SMMSP - MagSpec - Billabong Creek, NSW, 2001.

Geoscience for Australia's transition to net zero

Australia is well-positioned to remain a global energy supplier and be a leader in driving efforts to achieve net-zero greenhouse gas emissions. 
Australia has the potential to produce a range of low emissions energy commodities such as geothermal energy, natural and manufactured hydrogen, and natural gas linked with carbon capture and storage. Our ample solar and wind energy resources also support the deployment of renewable energy technologies across the country.
Our geological systems supply the raw materials — such as several of the critical minerals and strategic materials — that are needed to develop the infrastructure and manufacture the batteries and technologies that will support the energy transition. New and emerging opportunities have been identified for energy storage for energy produced from renewable sources, such as through manufacturing  hydrogen, hydrogen storage in underground salt caverns, and compressed air energy storage.
Australia is recognised for having a large potential to geologically store carbon dioxide. Carbon capture and storage technology can support industries that find it difficult to abate their emissions, including efforts to remove carbon dioxide directly from the atmosphere through use of direct air capture technology. 
Understanding the prospectivity for these resources and the current and emerging energy storage technologies will help to accelerate Australia's journey to a net-zero economy. 
As Australia’s national public sector geoscience organisation, Geoscience Australia continues to undertake national and regional research and data acquisition, to provide precompetitive data that underpins decision-making by governments and industry and attracts future investment.

Continental scale validation of analysis ready data in Australia: experience with satellite derived surface reflectance

Analysis Ready Data (ARD) are satellite data that have been pre-processed for immediate analysis with minimal user effort. The generation of Surface Reflectance (SR) from optical satellite data, involves a series of corrections to standardise the data and enable meaningful comparison of data from multiple sensors and across time. Surface reflectance data are foundational for time-series analyses and rapid generation of other information products. Field based validation of surface reflectance data is therefore critical to determine its fitness for purpose, and applicability for downstream product development. 
In this paper, an approach for continental scale validation of the surface reflectance data from Landsat-8 and Sentinel-2 satellites, using field-based measurements that are near-synchronous to the satellite observations over multiple sites across Australia is presented. Good practice measurement protocols governing the acquisition of field data, including field instrument calibration, sampling strategy and approach for post-collection processing and management of field spectral data are outlined.
This study has been a nationally coordinated, collaborative field data collection campaign across Australia. Permanent field sites, to support validation efforts within the broader Earth Observation (EO) community for continental scale products were also identified. The approach is expected to serve as a model for coordinated ongoing validation of ARD products at continental to global scales.

AusSeabed Bathymetry Survey Acquisitions Coverage Database

The AusSeabed Bathymetry Survey Acquisitions Coverage database contains polygon extents of bathymetry data acquisitions along with identifying attributes and contact details where the data is not held by Geoscience Australia.  It is an important scientific resource that identifies data spanning coastal, continental shelf and deep sea locations. 

This dataset is live and will continue to be augmented as coverage details are supplied from AusSeabed collaborators who wish to share their knowledge of data availability to the broader marine community. The database is updated regularly and is made available via the AusSeabed Marine Data Portal using OGC compliant web services. Surveys/Data Acquisitions have been conducted by a wide range of organisations and countries, both inside and outside Australia's marine jurisdiction, using multiple systems and for various applications. Data coverages are published where the polygon extents intersects with Australia's marine jurisdiction, including the Australian Antarctic Territory.  Each polygon in the layer contains metadata describing survey details. 
Note that polygons may not be representative of the true survey extent due to the data gridding process. 

For a list of source data contributions see Technical Lineage.
Please note that this public coverage does not include information that has been provided to Geoscience Australia under a Restricted and Exclusive license. However, the additional restricted information is used during the computation of Australian marine jurisdiction’s Percent Mapped assessment. 
Please contact us at ausseabed@ga.gov.au if you wish to contribute coverage information to the database.

Selection and ranking of ground-motion models for the 2018 National Seismic Hazard Assessment of Australia: Summary of ground-motion data, methodology and outcomes

One of the key challenges in assessing earthquake hazard in Australia is understanding the attenuation of ground-motion through the stable continental crust. There are now a handful of ground-motion models (GMMs) that have been developed specifically to estimate ground-motions from Australian earthquakes. These GMMs, in addition to models developed outside Australia, are considered in the 2018 National Seismic Hazard Assessment (NSHA18; Allen et al., 2017). 
In order to assess the suitability of candidate GMMs for use in the Australian context, ground-motion data forom small-to-moderate Australian earthquakes have been gathered.  Both qualitative and quantitative ranking techniques (e.g., Scherbaum et al., 2009) have been applied to determine the suitability of candidate GMMs for use in the NSHA18.  This report provides a summary of these ranking techniques and provides a discussion on the utility of these methods for use in seismic hazard assessments in Australia; in particular for the NSHA18.  The information supplied herein was provided to participants of the Ground-Motion Characterisation Expert Elicitation workshop, held at Geoscience Australia on 9 March 2017 (Griffin et al., 2018).
