Gippsland 2D Infill 2015 Marine Seismic Survey, (GA-0352) - High Resolution Bathymetry Grids

Geoscience Australia conducted a marine seismic survey (GA-0352) over poorly defined areas of the Gippsland Basin between 5th of April to the 24th of April 2015. The aim was to acquire industry-standard precompetitive 2D seismic data, Multi-beam echo-sounder (MBES) and sub-bottom profiling (SBP) data to support an assessment of the CO2 storage potential of the basin. The survey, undertaken as part of the Department of Industry and Science's National CO2 Infrastructure Plan (NCIP), aimed to identify and characterise indicators of natural hydrocarbon or fluid seepage that may indicate compromised seal integrity in the region. The data collected during this survey will enhance sequence stratigraphic studies in the Gippsland Basin that provide constraints on the most suitable areas for storage of CO2 and help to identify potential CO2 storage reservoirs. The survey was conducted by Gardline CGG vessel MV Duke The data collected during the survey are available for free download from the Geoscience Australia website. This dataset include all the bathymetry data collected during the survey.

This dataset is not to be used for navigational purposes.

Sorell Basin - Tasmania petroleum prospectivity bulletin

This Bulletin covers the offshore region west of Tasmania. The western margin of Tasmania, an area of 100,000 sq km contains a thick cover of Late Mesozoic and Tertiary sediments. Most of this sedimentary wedge lies within the Sorell Basin, an extensional passive margin basin that formed as part of the Southern Rift System in the Late Jurassic-Early Cretaceous. 
See Section 2 - Regional Geology for discussion of the regional geology and development of the western margin. 
Section 7 - Environmental Features discusses the marine environment and climatic and tidal effects on the western margin. The Sorell Basin Petroleum Prospectivity Package concentrates mainly on the northern part of the basin containing the King Island and Strahan Sub-basins. It is primarily in these two sub-basins that there is sufficient well and seismic data to assess the prospectivity of the Sorell Basin. 
See Section 6 - Prospectivity for the discussion of the basin's prospectivity.

Predicting Seabed Mud Content across the Australian Margin: Performance of Machine Learning Methods and their combinations with Ordinary Kriging and Inverse Distance Squared

In 2008, the performance of 14 statistical and mathematical methods for spatial interpolation was compared using samples of seabed mud content across the Australian Exclusive Economic Zone (AEEZ), which indicated that machine learning methods are generally among the most accurate methods. In this study, we further test the performance of machine learning methods in combination with ordinary kriging (OK) and inverse distance squared (IDS). We aim to identify the most accurate methods for spatial interpolation of seabed mud content in three regions (i.e., N, NE and SW) in AEEZ using samples extracted from Geoscience Australia's Marine Samples Database (MARS). The performance of 18 methods (machine learning methods and their combinations with OK or IDS) is compared using a simulation experiment. The prediction accuracy changes with the methods, inclusion and exclusion of slope, search window size, model averaging and the study region. The combination of RF and OK (RFOK) and the combination of RF and IDS (RFIDS) are, on average, more accurate than the other methods based on the prediction accuracy and visual examination of prediction maps in all three regions when slope is included and when their searching widow size is 12 and 7, respectively. Averaging the predictions of these two most accurate methods could be an alternative for spatial interpolation. The methods identified in this study reduce the prediction error by up to 19% and their predictions depict the transitional zones between geomorphic features in comparison with the control. This study confirmed the effectiveness of combining machine learning methods with OK or IDS and produced an alternative source of methods for spatial interpolation. Procedures employed in this study for selecting the most accurate prediction methods provide guidance for future studies.

D.F.S. No. 1 Betoota, Queensland Of Delhi-Frome-Santos

The Betoota No. 1 well was drilled by Delhi Australian Petroleum Ltd, Frome-Broken Hill Company Pty Ltd, and Santos Limited, in far southwest Queensland to a total depth of 9,824 feet. Drilling was commenced on 22nd December 1959 and the well was completed on 18th April 1960 as a dry hole. The rig used was a National 130 owned by Delta Drilling Company. Delhi Australian Petroleum Ltd, as the operating company, supplied the supervisory, engineering, and geological personnel. A comprehensive programme to obtain all data relative to the hydrocarbon potential of the strata penetrated by the drill bit and stratigraphic information concerning the geological history of the area was diligently carried out. The operation also provided for a complete programme of electric and mud logging, testing and coring, carried out by the operating company and their contracted service
companies.

The Betoota No. 1 well established the presence of 5,757 feet of Mesozoic strata overlying 4,067 feet of sediments of probable Palaeozoic age at the site of the bore hole. Several showings of hydrocarbons were detected in sediments between 4,400 feet and 5,757 feet. Mter testing and examination of all evidence, they were considered to be noncommercial. From 3,450 feet to 5,757 feet some zones exhibiting very good porosity were encountered, but all were found to be water-bearing. Shales of both marine and brackishwater origin, regarded as suitable source rocks, occurred in the well between 1,350 feet and 3,245 feet and between 5,000 feet and 5,757 feet. The rest of the section penetrated was
composed of sediments whose origin did not suggest conditions of accumulation likely to foster the generation of fluid hydrocarbons.

Great Barrier Reef, Ribbon Surficial Cover Facies maps

The Bureau of Mineral Resources has developed a reconnaissance-style mapping technique for documenting surficial cover on reefs. These maps exhibit only surficial facies. Subsurface facies will be integrated on future maps. A simple bathymetric classification has been applied to these maps with the differentiation of supratidal, intertidal and subtidal zones. The intertidal zone is confined to upper and lower levels that approximate highest astronomical tide and low water datum at Townsville respectively.  Map resolution is variable over the reef and generally it decreases with increasing water depth. Maximum resolution has been retained where possible, to provide the user with the means of location on these reefs.

The dataset comprises 429 individuals from 45 species of fishes, sharks, rays and sea snakes observed at around Inshore Shoals : Townsville using 5 baited remote underwater video stations (BRUVS(TM)). 67 images were captured from these cameras.

Approximately 3500 of the best images from all BRUVS (TM) projects are stored in a reference library.

Data recorded concern:
- classification of the habitat in the field of view (topography, sediments, benthos)
- the identity of fish and CAABCODES
- their time of arrival
- their behaviour (8 categories, including feeding on the bait)
- their maturity (adult or juvenile)
- their relative abundance (as MaxN = the maximum number visible at one time, or distinguishable at different times as separate individuals e.g. much larger/smaller, male/female)
- the time elapsed before MaxN and feeding occurs.

A custom interface has been developed by AIMS staff, using Microsoft Access, for reading and analysis of BRUVS(TM) tapes.

RV Investigator Voyage IN2024_V03 CTD Data

This record describes the CTD data collected on Investigator voyage IN2024_V03, titled: "Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 2) ." The voyage took place between May 01, 2024 and May 31, 2024 (AEST), departing from Hobart and returning to Sydney.

Data for 83 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #24 (S/N 1354), fitted with 18 twelve-litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.

CTD had minor issues at beginning of voyage. LADCP had a battery failure for the first three casts. A pump was replaced after cast 10 after primary conductivity and DO were different to the secondary values. No sensors were changed throughout the voyage.

The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (SD) of 0.0018351PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the primary sensors.

The dissolved oxygen data calibration fit had a SD of 0.83297μM. The agreement between the CTD and bottle data was good.

Altimeter (Tritech PA500), PAR (Biospherical QCP2300HP), CDOM (Wetlabs FLCDRTD), Chlorophyll-a, Scattering (Wetlabs ECO FLBBRTD) were also installed on the auxiliary A/D channels of the CTD.

The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

Additional information regarding this dataset may be contained in the Voyage Summary and the Data Processing Report.

GA339_SOL5650 Oceanic Shoals survey marine underwater video and still images

The Oceanic Shoals survey (SOL5650, GA survey 339) was conducted on the R.V. Solander in collaboration with Geoscience Australia, the Australian Institute of Marine Science (AIMS), University of Western Australia and the Museum and Art Gallery of the Northern Territory between 12 September - 5 October, 2012. 

During the survey, underwater video and still images were acquired using the AIMS towed camera system. Video was acquired using a forward-facing camera (files available in sub-folder 'NERP_TOWVID_VIDEOS'), and still images were acquired with a downward-facing camera, with images taken every 10 seconds (files available in sub-folder 'NERP_TOWVID_STILLS'). Video was converted from tapes to compressed .avi files. Video was characterised onboard in real-time using the AIMS' Towvid characterisation scheme. These characterisations are available in sub-folder 'NERP_TOWVID_CSVs'. 

Location of ship movement during camera and sled transects are included in the spreadsheet 'SOL5650_GA0339_Stations.xls'. Exact location of the camera during deployment is recorded via the USBL and can be found in sub-folder 'NERP_USBL'.

Video and associated still images were not acquired from STN13CAM09. Video is not available from 27CAM18 and 28CAM19 (these stations were not on the digital files supplied by AIMS), although still images and Towvid characterisations were supplied. Video Tape 12 is the same as Tape 11, as supplied by AIMS. All video files were renamed at GA with a prefix listing stations contained on a given tape/file. 

In addition to underwater imagery, laboratory and deck photos were taken of specimens collected from the benthic sled. These are included in the sub-folder 'NERP_SPECIMEN_PHOTOS'

Video and image files or associated parent folders are named by station number, gear code (CAM = underwater camera system, BS = benthic sled) and then the deployment number. For example '48CAM35' represents a video transect from Station 48 that was the 35th video transect on the survey.

Data is presented here exactly as acquired onboard and converted by the AIMS, and positional accuracy or image quality has not been verified.

Standard Operation Procedures for a Multibeam Survey: Acquisition & Processing

The Australian Maritime Jurisdiction of approximately 7,000,000 km2 has, at most, 25% of its seabed surveyed at high resolution. Since September 2001, under Commonwealth Policy on Spatial Data Access and Pricing, Intergovernmental Committee on Spatial Data Access and Pricing, the co-custodian of the bathymetry data collected within the Australian Marine Jurisdiction has been assigned to Geoscience Australia (GA). GA thus hosts various formats of raw as well as processed bathymetry datasets from multiple sensors, including multibeam sonar systems. The quality between datasets varies, depending on the objectives of the survey. As of January 2013, the multibeam sonar bathymetric coverage held by GA was acquired by 48 vessels, 26 different multibeam sonar systems in 9 different frequencies between 12 and 455 kHz. Consequently, GA has to deal with a variety of survey standards, making the post-processing and merging not efficient. The objective of this document is thus to provide standards and guidance to GA personnel and contractors who conduct multibeam data acquisition and processing during marine surveys to maximise consistency and efficiency. This document provides the most critical steps to multibeam acquisition and a mandatory checklist and deliverables. Specific details and tips for processing using Caris HIPS &amp; SIPS software and Kongsberg EM series data are also provided in the appendix.

Magnetite beach-sands of Bougainville Island, Territory of Papua and New Guinea

Magnetite with combined titanium dioxide, the predominant heavy mineral of the Bougainville beach sands, is derived from the unconsolidated pyroclastic and alluvial aprons of recent-active andesitic volcanoes principally Mt. Balbi in the north, Mt. Bagana in the centre and Mt. Taroka in the south. The spectacular high concentrations of magnetite on the eastern coast are probably too small for consideration as iron ore deposits. Magnetite sand concentrations of economic importance may exist in the large areas of coastal plain, particularly on the western side of the island, which are obviously made up of a succession of old strands. Magnetic survey methods may be of value in delineating zones of magnetite concentration in these areas.

Investigating the effect of silicate- and calcium-based ocean alkalinity enhancement on diatom silicification - data

These files contain the data recorded from a mesocosm experiment conducted in Bergen, Norway 2022 which assessed the effect of simualted mineral-based (silicate or calcium) ocean alkalinity enhancement (OAE) on diatom silicification. Ten mesocosms were used in total, divided into two groups either the silicate- or calcium based group and alkalinity was increased by either 0, 150, 300, 450 or 600  µmol L-1 above natrually occuring levels. The PDMPO-fluorescence (an appropriate proxy for silicification) of diatoms was recorded on eight seperate days during the experiment. Accompanying data includes measured; macronutrients (nitrate, nitrite, phophate, silicate), total alkalinity, biogenic silica in the water column and sediment trap.

The sediments of the Argo Abyssal Plain and adjacent areas, northeast Indian Ocean

A series of geophysical traverses by the Atlantis II across the Argo Abyssal Plain, together with coring at a number of selected localities has provided new information on sedimentary and tectonic processes in this region of the northeast Indian Ocean. Isopach maps prepared from the seismic profiles show that sediment thicknesses crudely parallel the bathymetry. The presence of some diapirs in the Argo Abyssal Plain was indicated. It was not possible to say from the present program whether the probable diapirs are salt or mud-cored. A diverse group of cores were obtained from a variety of sites including siliceous clays from below the CCD, calcareous oozes from above the CCD, calcareous clays (showing evidence of abundant sulphate reduction) from a fore-arc basin site, and manganese nodules from an abyssal site. In addition, hyaloclastites from the Joey Rise area (north of the Exmouth Plateau), suggest that the Joey Rise, and possibly also the Roo Rise, are underlain by basaltic material. A sample of basalt was also recovered from the outer part of the Exmouth Plateau.

This dataset is part of a broader survey carried out by EGS Survey Pty Ltd onboard the survey vessel RV Bold Explorer (RV BE) during the SUBCO Subsea Cable Network (SSCN) cable route survey.
The area is confined to the data within the Apollo Marine Park and was acquired between 24th Februarfy 2024 and the 5th March 2024.
The SUBCO Subsea Cable Network (SSCN) comprises a trunk route between Perth (Western Australia) and Sydney (New South Wales) with branches to Garden Island (Western Australia), Adelaide (South Australia), and Torquay (Victoria).
EGS Australia was contracted by OMS to supply hydrographic, geophysical, and geotechnical survey services, to provide data for engineering, construction, and subsequent maintenance of the SSCN Segment 2-C (BU TQW up to 206.3m WD). The primary purpose of the survey is to determine a viable and secure route for the cable system that is clear of excessive slopes (&gt;6°), sea floor conditions that will adversely affect ploughing and burial of the cable, and obstacles such as rock outcrops, cable spans, existing cables, pipelines, shipwrecks etc.
The SSCN Segment 2-C (BU TQW up to 206.3m WD) survey comprised an investigation of bathymetry, seabed features and shallow geology along the proposed route.
This dataset is not to be used for navigational purposes.
