Report on the Analysis of the Asia Pacific Regional Geodetic Project (APRGP) GPS Campaign 2018

The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an activity of the Geodetic Reference Frame Working Group (WG) of the Regional Committee of United Nations Global Geospatial Information Management for Asia and the Pacific (UN-GGIM-AP). This document describes the data analysis of the APRGP GPS campaign undertaken between the 16th and 22nd of September  2018. Campaign GPS data collected at 101 sites in ten countries across the Asia Pacific region were processed using version 5.2 of the Bernese GNSS Software in a regional network together with selected IGS (International GNSS Service) sites. The GPS solution was constrained to the ITRF2014 reference frame by adopting IGS14 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products. The average of the root mean square repeatability of the station coordinates for the campaign was 1.8 mm, 1.6 mm and 5.4 mm in north, east and up components of station position respectively.

Bathymetry of Bremer Marine Park

Australia has established a network of 58 marine parks within Commonwealth waters covering a total of 3.3 million square kilometres, or 40 per cent of our exclusive economic zone (excluding Australian Antarctic Territory). These parks span a range of settings, from near coastal and shelf habitats to abyssal plains. Parks Australia manages the park network through management plans that came into effect for all parks on 1 July 2018. Geoscience Australia is contributing to their management by collating and interpreting existing environmental data, and through the collection of new data. This includes compiling existing bathymetry datasets for select marine parks. This dataset includes a compilation of multibeam sonar bathymetry (gridded to 100 m spatial resolution) for Bremer Marine Park, in the South-west Marine Park Network. The park incorporates Bremer Canyon and adjacent smaller canyons that incise the continental slope and outer shelf. This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.This dataset is not to be used for navigational purposes.

Gifford Marine Park Bathymetry - 30m Resolution Grid

Australia has established a network of 58 marine parks within Commonwealth waters covering a total of 3.3 million square kilometres, or 40 per cent of our exclusive economic zone (excluding Australian Antarctic Territory). These parks span a range of settings, from near coastal and shelf habitats to abyssal plains. Parks Australia manages the park network through management plans that came into effect for all parks on 1 July 2018. Geoscience Australia is contributing to their management by collating and interpreting existing environmental data, and through the collection of new marine data. “Eco-narrative” documents are being developed for those parks, where sufficient information is available, delivering collations and interpretations of seafloor geomorphology, oceanography and ecology. Many of these interpretations rely on bathymetric grids and their derived products, including those in this data release. Bathymetry grids The bathymetry of the marine parks was created by compiling and processing Geoscience Australia’s bathymetry data holding gridded at the optimum resolution depending of the vessel’s sonar system. The bathymetry of the park is illustrated by a panchromatic geotiff image, developed by combining the bathymetric data with a hillshade image.  Morphological Surfaces Geoscience Australia has developed a new marine seafloor classification scheme, which uses the two-part seafloor mapping morphology approach of Dove et al (2016). This new scheme is semi-hierarchical and the first step divides the slope of the seafloor into three Morphological Surface categories (Plain, 10°).

Mapping groundwater dependence in data poor areas: analysis of earth observation data in the Isa Geological and Bioregional Assessment region, north-west Queensland Australia

The Australian Government's Geological and Bioregional Assessment (GBA) Program is assessing potential impacts of shale and tight gas development on water resources and the environment in three onshore basins: Cooper, Isa and Beetaloo. The Isa GBA region is host to two major groundwater systems: a deeper Proterozoic system and a shallower system associated with sediments of the Carpentaria and Karumba basins, collectively part of the Great Artesian Basin. If shale gas were to be developed in the future there could be potential to impact groundwater and surface water and the ecosystems that rely on these resources. 
Surface water – groundwater interactions are a key component of the hydrological system, important for supporting a variety of environmental assets. Analysis of Earth observation data in this remote region has helped assess the interactions between surface water and groundwater where the availability of other spatial and temporal datasets is limited. In particular, new remote sensing methods have enabled rapid and consistent mapping of parts of the landscape with potential dependence on groundwater.
Two remote sensing products (Water Observations from Space summary statistics and Tasselled Cap Index wetness exceedance) were used to investigate the persistence of surface water and soil moisture in the landscape. In this region, areas that retain water for at least 80% of the time or are wet during the dry season (May to October) are likely to have a reliable groundwater source or access to groundwater during periods of limited rainfall. These areas most likely support groundwater dependent ecosystems, including springs. 
Preliminary analysis of Earth observation data has enhanced understanding of surface water – groundwater interactions in the Isa GBA region, complementing analysis of sparse streamflow, groundwater and hydrochemistry data. Targeted field validation could improve understanding of groundwater dependence in the landscape and enhance confidence in the findings of this assessment.

Illuminating the Biodiversity of the Cape Range and Cloates Canyons (FK200308/GA4859)

This resource includes bathymetry data acquired during the Submarine Cape Range Canyons bathymetry survey using Kongsberg EM302 and EM710 multibeam sonar systems. The Seamounts, Canyons and Reefs of the Coral Sea bathymetry survey was led by Dr. Rachel Przeslawski (Geoscience Australia) with a team of scientists from Geoscience Australia, Curtin University, Western Australian Museum and Scripps Institution of Oceanography aboard the Schmidt Ocean Institute (SOI) RV Falkor from the 8th of March to the 8th of April 2020. 
The primary objective of this survey was to map unexplored submarine canyons in the Gascoyne Marine Park. Submarine canyons are crucial habitats for a variety of biota and understanding their geometry, depth and species diversity is underpinned by high resolution bathymetry data. The bathymetry data collected in this survey can assist with scientific research, marine park management and understanding Australia’s marine estate.
This dataset contains a 64m and a 16m, for water depths shallower than 2560m resolution 32-bit geotiff of the Cape Range and Cloates Canyons area produced from the processed EM302 and EM710 bathymetry data combined.

Exploring for the Future- X-Ray Diffraction (XRD) data release of sedimentary rocks in the South Nicholson Basin and Isa Superbasin, Northern Australia

The Exploring for the Future program is an initiative by the Australian Government dedicated to boosting investment in resource exploration in Australia. The four-year program led by Geoscience Australia focusses on northern Australia and parts of South Australia to gather new data and information about the potential mineral, energy and groundwater resources concealed beneath the surface. As part of the Exploring for the Future program, this study aims to improve our understanding of the petroleum resource potential of northern Australia. As a component of this project, collaboration between the Onshore Energy Systems Branch of Geoscience Australia, the Geological Survey of Queensland (GSQ) and Northern Territory Geological Survey (NTGS) is designed to produce pre-competitive information to assist with the evaluation of the petroleum prospectivity of onshore Northern Territory basins. 
This data release contains X-Ray Diffraction (XRD) data of 600 samples selected from 12 drill cores from the South Nicholson Basin and Isa Superbasin that are housed in GSQ’s Brisbane core repository and NTGS’s Darwin core repository. These samples covered nine formations: the Mesoproterozoic Mullera Formation (n = 11) and Constance Sandstone (n = 91) of the South Nicholson Basin, in addition to the Paleoproterozoic Lawn Hill Formation (n = 210), Doomadgee Formation (n = 34), Termite Range Formation (n = 36), Riversleigh Siltstone (n = 96), Mount Les Siltstone (n = 32), Lady Loretta Formation (n = 3) and the Walford Dolostone (n = 66) of the Isa Superbasin. This data was generated at the Inorganic Geochemistry Laboratory at Geoscience Australia as part of the Exploring for the Future (EFTF) program. 
The results demonstrated that 23 different minerals were identified in the entire region. Out of these minerals there were seven dominant minerals; quartz, kaolinite, microcline, muscovite, dolomite, calcite and siderite. These dominant mineral components were highly variable between all formations analysed in this study, demonstrating the utility of high resolution XRD to determine mineral compositions and variability through sedimentary successions. 
This publically available dataset is provided in preparation for future work to generate statistics quantifying the spatial distribution and composition of sedimentary rocks, providing information to de-risk resource decision making and investment of northern Australian basins.

The Australian Government's role in reducing community risk: the National Flood Risk Information Project

In the summer of 2010-11, south-eastern Australian experienced a significant number of major flood events, culminating in the flooding of Brisbane in January 2011. The losses experienced by these events initiated the National Disaster Insurance Review to assess whether appropriate national measures were in place to foster more complete sharing of risk. The review highlighted the need for consumers to be more aware of the risk they may face to enable informed decisions to be made on where to live. In response to the recommendations of the review, the Australia Government determined that a 4 year programme to improve the quality, availability and accessibility of flood information across Australia should be undertaken. 
In July 2012, Geoscience Australia initiated the National Risk Information Project (NFRIP) to meet this objective. NFRIP was comprised of three core activities;
- Australian Rainfall and Runoff: improving the quality of future flood information by completing the revision of the Australian Rainfall and Runoff guidelines.
- Australian Flood Risk Information Portal: working towards making legacy flood information and associated mapping freely available from a central location through an online portal. 
- Water Observations from Space: analysis of the Geoscience Australia's historic archive of satellite imagery to derive water observations to help understand where flooding may have occurred in the past in areas of Australia.
The presentation will outline the NFRIP outputs, discuss some of the challenges encountered in making hazard and risk information available to the community, and use of the Creative Common Attribution 4.0 license in overcoming them.

Seasonality of groundwater discharge to streams: implications for water management in Australia

An understanding of the interaction between groundwater and surface water systems is fundamental to the effective management of water resources. Importantly, groundwater discharge to streams often accounts for a significant proportion of total streamflow, particularly during low-rainfall periods. This study has applied a consistent approach to classifying streams and assessing groundwater discharge to streams in order to characterise streamflow and baseflow patterns in different geographic regions across Australia.
Historical streamflow data for 233 Australian stream gauges were analysed. Long‐term and seasonal (high‐flow and low‐flow) baseflow indices (BFI) were determined using the Lyne and Hollick recursive digital filter to quantify the relative baseflow component of streamflow. Classifying streams into perenniality and seasonality groups highlights distinct characteristics of baseflow regarding timing, magnitude and variability.
Five distinct perenniality groups were identified by hierarchical clustering of percentage flow days. Non‐perennial streams (flow &lt; 90% of the time) have a long‐term mean BFI of 0.25 while perennial streams (flow &gt; 90% of the time) have a long‐term mean BFI of 0.46.
Two overarching seasonal flow regimes (Summer or Winter‐dominant) or eight sub‐groups were distinguished by hierarchical clustering of mean monthly streamflow data. Streams within each of the seasonal flow regimes have a characteristic streamflow and baseflow pattern. All streams assessed in Northern Australia are Summer‐dominant; a number of these streams have sustained baseflow throughout the dry season. Winter‐dominant streams predominate in the southern half of Australia. The timing and relative discharge of groundwater to streams vary between seasonal flow regimes due to differences in the dominant sources of water to the stream at different times of the year.
Knowledge of stream perenniality, seasonal streamflow regimes and the respective streamflow and baseflow relationships is important from a water management perspective, particularly for conjunctive use of groundwater and surface water resources.
