Videos from CEAMARC AA032007 (Collaborative East Antarctic Marine Census)

The Collaborative East Antarctic Marine Census (CEAMARC) voyage was conducted on the Aurora Australis between December 2007 and January 2008. The voyage was operated as part of the Census of Antarctic Marine Life (CAML) program to document the benthic communities and their associated habitats across the George V Shelf in east Antarctica. Underwater video footage was collected from 22 sites across the shelf using Geoscience Australia's Deep Under Water Camera (DUCII). Transects were run for 15-40 minutes across depths ranging from 140 m to 1200 m. All video footage is stamped with the UTC time. Stations are named according to the CEAMARC station number followed by the instrument used (eg. CAM for camera) and then the deployment number. For example 09CAM05 was deployed at CEAMARC site 9 and was the 5th camera transect. The location and depth of each station is listed below.

Esso Gippsland Shelf No 1 Well Victoria Of Esso Exploration Australia, Inc

Esso Gippsland Shelf No. I, Australia's first offshore well, was drilled by Esso Exploration Australia, Inc., in the Gippsland Basin, about sixteen miles off the Ninety Mile Beach, south-eastern Victoria.

Gippsland Shelf No. 1 was spudded on 27th December, 1964, reached a total depth of 8701 feet on 31st May, 1965, and was completed as a suspended gas well on 5th June, 1965. The 268-foot drilling vessel "Glomar III" owned and operated by Global Marine Australasia pty Ltd was used to drill the well.

The well penetrated a Tertiary section to 5378 feet and an Upper Cretaceous section from 5378 feet to 8701 feet, total depth. 353 feet of gas column was logged in the top of the Eocene Latrobe Valley Coal Measures, which proved to be productive by subsequent tests. Minor hydrocarbon shows in the Upper Cretaceous section are considered to be noncommercial.

Three production tests were made through perforations opposite sandstones in the Latrobe Valley Coal Measures; one to confirm the gas-water contact and two for reservoir evaluation. On the first and lowermost test from 3809 to 3814 feet the well flowed gas at the maximum rate of 1.63 MMcf/D and fresh water at the rate of 750 barrels a day. On the other tests the maximum flow rates were 6.85 MMcf/D plus 75 barrels of consensate a day, and 5.36 MMcf/D plus 79 barrels of condensate a day.

The well was the first offshore discovery in Australia, and gave the first significant production from the Latrobe Valley Coal Measures. It was also the first occurrence of a porous sandstone member in the Gippsland Limestone; the first occurrence of porous sandstone members in the Upper Cretaceous section; and the first occurrence of a Mesozoic section younger than the Strzelecki Group in the Gippsland Basin.

A new and unknown sandstone section some 369 feet thick was encountered in the lower part of the Gippsland Limestone. The areal extent of this section is as yet unknown. Otherwise the lithology of the Tertiary sequence was as expected.

The stratigraphic drilling operation at Esso Gippsland Shelf No. 1 was subidized under the Petroleum Search Subsidy Act 1959-1964, from surface to total depth.

Quaternary and modern environments of the Van Diemen Rise, Timor Sea, and potential effects of additional petroleum exploration activity

Environmental baseline data are required for Australias offshore areas before petroleum exploration. This has boosted demand for analysis and interpretation of the Quaternary evolution, modern geological processes and environmental features of the Australian continental shelf. One such area overlies the Van Diemen Rise on the Sahul Shelf in the eastern Timor Sea. Sea bottom sediments in the region are dominantly calcareous sand derived from skeletal carbonate material. A number of sinuous channel-like features cut through a series of terraces and banks which comprise the Van Diemen Rise. These features are the product of subaerial exposure and weathering of the underlying carbonate shelf during the last Quaternary glacial maximum. At about 18 000 BP sea level was ~120 m below the present shoreline, much of which was subjected to subaerial exposure and erosion. Only a narrow marine shelf existed close to the outermost edge of the present continental shelf.  Shallow banks and shoals on this narrow shelf were the focus of significant coral reef growth. Calcrete concretions formed on the exposed land surface. Holocene transgression inundated the entire margin and shifted reef growth onto the shallowest parts of the flooded banks and terraces. Today sedimentation within the 50 m contour is entirely clastic and derived from wet-season river input.  On the outer shelf foraminiferal calcarenites are being deposited.  These become finer-grained and contain more planktonic components the greater the water depth. Silty clays and molluscan debris are accumulating in the sheltered channels between the banks and terraces of the Van Diemen Rise.  Large foraminiferal and coralline algae dominate the shallow banks and rises. An assemblage dominated by Halimeda is growing on the outermost shelf edge banks. Seismic surveying and drilling are the main activities likely on the Van Diemen Rise. The short-term nature of these activities would cause no long-term impact on environmental conditions.  They would cause minor short-term localised disturbance. Rock fragments from exploration drill sites would be dispersed by normal current and tidal action within a short period.

National Gravity Compilation 2019 (CSCBA 1VD grid)

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 (CSCBA 1VD grid) is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the 2019 Australian National Gravity Grids A series. This gravity survey was acquired under the project No. 202008. The grid has a cell size of 0.00417 degrees (approximately 435m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.

Polychaetes (Annelida) of the Oceanic Shoals region, northern Australia: considering small macrofauna in marine management

Northern Australia has been the focus of recent marine biodiversity research to support natural resource management for both industry and conservation, including management of the Oceanic Shoals Australian Marine Park (AMP). Much of this research has targeted habitat-forming sessile invertebrates and charismatic megafauna, but smaller macrofauna and infauna may also be important because of their  roles in ecosystem functions. In this study we characterised the biodiversity of polychaetes collected from four marine surveys to the Oceanic Shoals AMP between 2009 and 2012 from which sediment samples were elutriated (500 μm) to separate macrofauna. We used this species-level inventory to examine several questions related to marine management, namely: (1) do polychaete assemblages vary among surveys; (2) can environmental variables or geomorphology explain differences in community structure; and (3) how do ecological patterns change according to taxonomic resolution (species, family) and functional group (feeding, habitat, mobility)? A total of 2561 individual polychaetes were collected from 266 samples, representing 368 species and 43 families, including new species and genera, as well as new family records for Australia (Iospilidae, Lacydoniidae). Polychaete species assemblages and functional groups showed variation among the surveys, but this was not observed at the family level. Species and family assemblages were weakly related to environmental factors, but functional groups showed stronger relationships. Plains and banks each supported distinct polychaete assemblages, although the latter showed temporal variation. The results provide baseline biodiversity and ecological data about polychaetes on the northern Australian shelf, and these are discussed in relation to marine management strategies. Notably, intersurvey and environmental patterns differ from those of larger sessile fauna (sponges) collected on the same surveys, highlighting the need to consider small macrofauna in monitoring programs of marine protected areas.

Topographic Controls on Post-Oligocene Changes in Ice-sheet Dynamics, Prydz Bay Region, East Antarctica

Within the general trend of post-Eocene cooling, the largest and oldest outlet of the East Antarctic Ice Sheet underwent a change from ice-cliff to ice-stream and/or ice-shelf dynamics, with an associated switch from line-source to fan sedimentation. Available geological data reveal little about the causes of these changes in ice dynamics during the Miocene Epoch, or the subsequent effects on Pliocene-Pleistocene ice-sheet history. Ice-sheet numerical modeling reveals that bed morphology was probably responsible for driving changes in both ice-sheet extent and dynamics in the Lambert-Amery system at Prydz Bay. The modeling shows how the topography and bathymetry of the Lambert graben and Prydz Bay control ice-sheet extent and flow. The changes in bathymetric volume required for shelf-edge glaciation correlate well with the Prydz Channel fan sedimentation history. This suggests a negative feedback between erosion and glaciation, whereby the current graben is overdeepened to such an extent that shelf-edge glaciation is now not possible, even if a Last Glacial Maximum environment recurs. We conclude that the erosional history of the Lambert graben and Prydz Bay in combination with the uplift histories of the surrounding mountains are responsible for the evolution of this section of the East Antarctic Ice Sheet, once the necessary initial climatic conditions for glaciation were achieved at the start of the Oligocene Epoch.

Permian pelecypods and gastropods from Western Australia

The present work has been undertaken as part of a long-term project of describing the Permian pelecypod and gastropod faunas of Western Australia and western Northern Territory and of assessing their stratigraphical significance. Two portions have already appeared (Dickins, 1956; 1957). In the first paper pelecypods from earlier collections obtained from various parts of the sequence in the Carnarvon Basin were described; and in the second the earliest Permian (Sakmarian) pelecypod and gastropod fauna from the Lyons Group and the Carrandibby Formation. Other current work in palaeontology is being undertaken by B. E. Balme (pollen and microplankton), B. F. Glenister (ammonoids), G. M. Philip (crinoids and blastoids), June R. P. Ross (bryozoans), and G. A. Thomas (brachiopods). For faunal studies, the Permian rocks of the western part of Australia have the merit that the Lower Permian* has a complex of changing marine faunas which allow a detailed study of their phylogeny and range. The value of this sequence is enhanced by the presence of marine Upper Permian in the Fitzroy and Bonaparte Gulf Basins. It represents as complete a marine Permian sequence as any in Australia, if not the most complete, and is rivalled only by that of the Hunter Valley of New South Wales. The collections used have been mainly from the Geology Department of the University of Western Australia and from the Museum of the Geological Branch of the Bureau of Mineral Resources, Geology and Geophysics, Canberra. The Bureau of Mineral Resources collections include material from West Australian Petroleum Pty Limited.

Bynoe Harbour Marine Survey 2016: GA4452/SOL6432 Post-survey report

This report provides a description of the activities completed during the Bynoe Harbour Marine Survey, from 3 May and 17 May 2016 on the RV Solander (Survey GA4452/SOL6432). This survey was a collaboration between Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and Department of Land Resource Management (Northern Territory Government) and the second of four surveys in the Darwin Harbour Seabed Habitat Mapping Program. This 4 year program (2014-2018) aims to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline information and developing thematic habitat maps that will underpin future marine resource management decisions. The program was made possible through funds provided by the INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The specific objectives of the Bynoe Harbour Marine Survey GA4452/SOL6432 were to:
1. Obtain high resolution geophysical (bathymetry) data for the deeper areas of Bynoe Harbour (&lt;5 m), including Port Patterson; and,
2. Characterise substrates (acoustic backscatter properties, sub-bottom profiles, grainsize, sediment chemistry) the deeper areas of Bynoe Harbour (&lt;5 m), including Port Patterson.
Data acquired during the survey included: 698 km2 multibeam sonar bathymetry, water column and backscatter; 102 Smith-McIntyre grabs, 104 underwater camera drops, 29 sub-bottom profile lines and 34 sound velocity profiles.

Distribution of Triassic Reefs in the Northern Exmouth Plateau and Offshore Canning Basin : (Project 121.23) BMR Offshore Sedimentary Basins Program

Petroleum exploration on the Exmouth Plateau has ceased, althoughthe giant Scarborough Gas Field has been retained by Esso-BHP.Research cruises by BMR's vessel "Rig Seismic" and the associated
assessment of other data, indicate that the plateau still has petroleumpotential, but the combination of deep water and low oil pricesmilitates against further exploration at present.
However, the Ocean Drilling Program (ODP) core drilling on theWombat Plateau, in the far north of the Exmouth Plateau area, showedthat Rhaetian (Latest Triassic) reefs are present there, one beingdrilled at Site 764 (Fig. 1). This discovery was the first of aTriassic reef in Australia, and indicates that suitable conditions forreefal development are likely to be widespread on the Northwest Shelf.The existence of Late Triassic reef complexes suggests a new petroleumexploration play, with the reefs forming traps, and lagoonal faciesperhaps providing oil source potential. BMR has recently suggestedthat there is a 50% chance of Triassic reefs hosting 60 million barrelsof undiscovered oil on the Northwest Shelf.
BMR's Marine Division intends to assess the potential of suchreefs and other known Triassic and Jurassic shelf carbonates in twophases. The first is to map the known reef complexes on the WombatPlateau, and to see how far they can be extended along the northernmargin of the Exmouth Plateau and into the Canning Basin. The secondis to take our knowledge of their seismic character, and the bestseismic parameters for mapping them, into the outer Bonaparte Basinwhere Triassic carbonate sequences up to 1000 m thick have beendrilled, but no reefs have yet been identified.
The present project makes up the first phase of work, on thenorthern Exmouth Plateau. It is proposed that a 34 day cruise of "RigSeismic" be carried out in early 1990. This cruise should result inthe acquisition of 2500 km of multichannel seismic profiles on thenorthern Exmouth Plateau, about 15 dredges aimed at Triassic andJurassic carbonates, and up to 5 cores. The cruise and its post-cruisefollow-up work aim to
(i)Map the extent of and facies changes within the
Triassic/Jurassic carbonates in and south of Wombat Plateau, andin the Rowley Sub-basin of the southwestern Canning Basin, usingseismic profiling and dredging techniques.
(ii)Define the extent, character and petroleum potential of any
Triassic or Jurassic reefs found.
(iii)Use the cruise results, along with other data, to help assessthe petroleum prospects of Mesozoic reef plays elsewhere on theNorthwest Shelf.
(iv)Better define the geological history of the northern Exmouth
Plateau and the adjacent southwest Canning Basin.

Stock assessment of Macrocystis pyrifera beds at varying locations on Tasmania's south and east coasts 1950-1953, published 1954

Surveys were conducted as part of an assessment of the Macrocystis pyrifera (Linnaeus) C. Agardh 1820 beds on the east coast of Tasmania by the Commonwealth Scientific and Industry Research Organization (CSIRO) Division of Fisheries seaweed program in the early 1950's. Surveys were conducted because of interest in the Macrocystis beds as a source of alginates. Surveys were done between 1950 and mid 1953. The paper was published in 1954.
