National Gravity Compilation 2019 includes airborne CSCBA image

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 National Gravity Compilation 2019 includes airborne CSCBA image is an image derived from the 2019 Australian National Gravity Grids B series. These gravity data were acquired under the project No. 202008. The grid used to produce this image has a cell size of 0.00417 degrees (approximately 435m). The data are given in units of um/s^2, also known as 'gravity units', or gu. This gravity anomaly grid is derived from ground observations stored in the Australian National Gravity Database (ANGD) as at September 2019, supplemented by offshore data sourced from v28.1 of the Global Gravity grid developed using data from the Scripps Institution of Oceanography, the National Oceanic and Atmospheric Administration (NOAA), and National Geospatial-Intelligence Agency (NGA) at Scripps Institution of Oceanography, University of California San Diego. Out of the approximately 1.8 million gravity observations, nearly 1.4 million gravity stations in the ANGD together with Airborne Gravity surveys totaling 345,000 line km and 106,000 line km of Airborne Gravity Gradiometry were used to generate this grid. The ground gravity data used in this grid has been acquired by the Commonwealth, State and Territory Governments, the mining and exploration industry, universities and research organisations from the 1940's to the present day. Station spacing varies from approximately 11 km down to less than 1 km, with major parts of the continent having station spacing between 2.5 and 7 km. Airborne surveys have a line spacing ranging from 0.5 km to 2.5 km. The image shows complete Bouguer anomalies (B series) over Australia and its continental margins. Terrain corrections to gravity were calculated using both offshore bathymetry and onshore topography data.

The Mesozoic strata of Katherine and Fergusson River 1:250 000 sheets

Lower Cretaceous strata of the Katherine and the Fergusson River 1:250,000 Sheets were examined during the 1960 and 1961 field seasons. Field observations on lithology and palaeogeography were summarised in previous Records (Skwarko,1961a,b) and these, together with the identification of the fossils collected and their dating have provided material for conclusions expressed in the present Record. Of the thirteen assemblages of fossils collected on the Katherine-Ferguson River area, nine are marine and four consist of plant remains. They appear to range in age from Neocomian to uppermost Albian. Lower Cretaceous sediments.

Airborne gravity and gravity gradiometry data were also included to provide better resolution to areas where ground gravity data was not of a suitable quality. Out of the approximately 1.8 million gravity observations, nearly 1.4 million gravity stations in the ANGD together with Airborne Gravity surveys totaling 345,000 line km and 106,000 line km of Airborne Gravity Gradiometry were used to generate this grid. The ground and airborne gravity data used in this grid has been acquired by the Commonwealth, State and Territory Governments, the mining and exploration industry, universities and research organisations from the 1940's to the present day. Station spacing for ground observations varies from approximately 11 km down to less than 1 km, with major parts of the continent having station spacing between 2.5 and 7 km. Airborne surveys have a line spacing ranging from 0.5 km to 2.5 km. The grid shows de-trended global isostatic residual anomalies over Australia and its continental margins. This National Gravity Compilation 2019 includes airborne DGIR grid (DGIR) was obtained by subtracting 3 quantities (i.e., the near-field isostatic correction, the far-field isostatic correction, and a first order trend correction) from Complete Bouguer Anomaly data (CBA) of the 2019 Australian National Gravity Grids B series.

Carnarvon Shelf Survey Post-Cruise Report

This report provides a description of the CERF Marine Biodiversity Hub's survey of the Carnarvon Shelf, Western Australia, in August and September, 2008. The survey was a collaboration between the Australian Institute of Marine Science (AIMS) and Geoscience Australia (GA) aboard RV Solander, as part of the Hub's Surrogates Program. The purpose of field surveys in the Surrogates Program is to collect high-quality, accurately co-located data to enable the robust testing of a range of physical parameters as surrogates of patterns of benthic biodiversity in strategically selected, spatially discrete areas that are representative of much broader benthic environments. 

The report describes the methods employed in the survey and the datasets collected. Additional processing of most of the physical data (wave and current measurements, multibeam sonar bathymetry and backscatter, sediment grab samples, acoustic sediment profiles) and biological data (towed underwater video and stills photography, bottom sediment samples, near-bottom plankton samples) collected is required before comparative analysis between the data sets can commence. However, a number of initial interpretations of the physical data have been made and examples of the types of biota encountered in the towed video and stills photography and initial interpretations of the benthic communities encountered, are provided. The survey was focussed on three strategically selected study areas on the southern Carnarvon Shelf at Mandu, Point Cloates and Gnaraloo. A small additional area was also examined near the Muiron Islands, in the mouth of Exmouth Gulf, at the end of the survey.

Ashmore Reef's sedimentological response to the Holocene sea level rise

Positioned at the transition zone of the major hydrocarbon provinces of Browse and Bonaparte Basins, Ashmore Reef is built on what is thought to be Pleistocene antecedent topography.  This mature, ovoid, shelf-edge reef experiences the seasonal oceanic influences of Indian Ocean and of the Indonesian-Through-Flow. The model for its development is derived from the post glacial (past 11,000 years) relative sea level curve, C14 dated facies changes and the reef growth phases extrapolated from the One Tree Reef model (Marshall &amp; Davis 1982).  A thorough visual examination of the reef was augmented with a series of 12 vibro-cores through algal-foraminiferal sand and coral, across the bioturbated platform. Changes in the lagoonal sediment facies were carbon dated giving dates ranging from 970 to 2020 (~70 years) BP.  They indicated a major bio-facies change from robust vertical coral columns to an algal dominated reef crest and reef flats as sea level stabilised at ~2000 BP. Ashhmore Reef is presently characterised by high biodiversity and extensive coral growth, broad reef flats littered with coral boulders, and three vegetated cays.  An extensive series of highly mobile and heavily bioturbated biogenic sand sheets adjoin two lagoons.  Both are within a pronounced ovoid, algal-cemented, reef rim.  The sediments comprised principally of Halimeda sp., coral fragments, foraminifera, molluscs and a range of coralline algae that infill the lagoon at up to 0.73 cm/yr.  The three vegetated cays are capped with guano and all have wash-over deposits of pumice, wood, shell and coral.

Pre-cruise Report - Prydz Bay - MacRobertson Shelf and Kerguelen Plateau, February-April 1995 : AGSO Cruise 149, R.V. Aurora Australis

This record describes the background, aims and methods to be employed in the second AGSO/Antarctic Co-operative Research Centre/ANARE marine geoscience program in Prydz Bay and the Mac. Robertson Shelf. The cruise program consists of activities aimed at understanding modern sedimentary processes on the Antarctic margin, understanding the Plio-Pleistocene environmental history of the region and obtaining samples from the Kerguelen Plateau to illuminate the history of watermass reorganisation in the Southern Ocean during Quaternary. Climate change episodes.

The cruise will address goals set by the Antarctic CRC Natural Variability (sediments) sub-program, which are to promote a better understanding of global climate change by providing statements of the Antarctic and Southern Ocean palaeoenvironments over the following time intervals:

(A)0-10,000 years (post-glacial warming)

(B)0-160,000 years (last glacial cycle)

(C) 0-5,000,000 years (Pliocene "warming" of Antarctica)

These goals will be achieved by studying the Antarctic and Southern Ocean sedimentary record for evidence of Antarctic ice sheet and Southern Ocean circulation changes.

The development of accurate predictive models of climate change requires an understanding of the behaviour and interaction of components of global climate systems. The East Antarctic Ice Sheet is one such major component so that the study of its behaviour during past climatic fluctuations should provide key guidelines for climatic modelling. Sediments deposited in Prydz Bay contain a record of icesheet fluctuations because this area is located at the downstream end of the largest outlet glacier flowing from the East Antarctic Ice Sheet, the Lambert Glacier-Amery Ice shelf.

Another major component of the global climate system is the Southern Ocean. Water masses of the Southern Ocean play a pivotal role in world climate by absorbing, transporting and releasing heat and by transferring oxygen, nutrients and CO2 to and from the deep ocean. In

this context, the Kerguelen Plateau has accumulated sedimentary sequences that will contain records of how the polar front and its associated water masses have varied between glacial and interglacial periods.

The three geographical features targeted for study during the cruise are: (A) the trough-mouth fan deposits adjacent to Prydz Bay; (B)sediment traps associated with deep, shelf-basins on the Mac. Robertson Shelf; and (C) depositional basins on the Kerguelen Plateau. In the following sections the existing data bases for these areas are discussed and the objectives for the 1995 cruise of Aurora Australis are presented.

Coastal and Estuarine Studies: Interactions between Macro- and Microorganisms in Marine Sediments

Marine sediments support complex interactions between macro- and microorganisms.  What is the state of the science on such interactions from costal and estuarine environments to the deep sea? How does such knowledge effect environmental management? And what does future research hold in store for scientists, engineers, resource managers, and educators?

Marine Sediments: Interactions between Macro- and Microorganisms responds to these questions, and more, by focusing on: 

-Interactions between plants, microorganisms, and marine sediment 
  -Interactions between animals, microorganisms, and marine sediment 
  -Interactions between macro- and microorganisms and the structuring of benthic communities 
  -Impact of animal and plant activity on sediment geochemistry 
  -Conceptual and numeric models of interactions between macro- and microorganisms  

Here is an authoritative overview of the research, experimentation and modeling approaches now in use in our rapidly evolving understanding of life in marine sediments.

Elizabeth and Middleton Reef multibeam sonar backscatter survey (GA4848)

This resource includes multibeam sonar backscatter data for Middleton Reef and Elizabeth Reef within Lord Howe Marine Park collected by Geoscience Australia during the period 31 January to 6 February 2020 on the Australian Maritime College vessel, TV Bluefin. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with the Institute for Marine &amp; Antarctic Studies (University of Tasmania), NSW Department of Primary Industries, University of Sydney (Australian Centre for Field Robotics) and Parks Australia (Marine Park managers, Commonwealth Government). The purpose of the survey was to collect baseline information for benthic habitats within the National Park Zone (Middleton Reef) and Recreational Use Zone (Elizabeth Reef) of the marine park. These data will support ongoing environmental monitoring within the Temperate East Marine Park Network as part of its 10-year management plan (2018-2028). Data acquisition for the project included seabed mapping using multibeam sonar (Kongsberg EM 2040C HD, 300 kHz), seabed imagery acquisition by Autonomous Underwater Vehicles (AUV Sirius and AUV Nimbus), sediment samples (grab) and imagery of demersal fish communities by baited remote underwater videos (BRUVs). This dataset comprises two bathymetry grids derived from multibeam sonar data gridded at 4 mspatial resolution. A detailed report on the survey is available on the Marine Biodiversity Hub’s website (https://www.nespmarine.edu.au/reports;  Carroll, A et al., 2020,.
