Exmouth Offshore Resource Map Series 1:1m

The Tasmante bathymetry survey, GA-0125 was acquired by Geoscience Australia onboard the IFREMER N/O L'Atalante from the 12th of February to the 28th of March 1994 using a Simrad EM12 Dual sonar system. The objectives of the west Tasmanian swath-mapping cruise (Tasmante) are to: determine the structure of the continental margin off west Tasmania, on the South Tasman Rise, and on the adjacent abyssal plain; examine the relationships between lithospheric extension in continental crust, the orientation of the seafloor spreading phases, and the formation of the transform margin along west Tasmania and the South Tasman Rise; map sedimentary patterns and processes to build an understanding of Neogene changes in sedimentation and their relationship to tectonic and climatic. This dataset contains a 100m resolution 32-bit geotiff of the Tasmante survey, produced from the processed EM12D bathymetry data of the survey area using the CARIS HIPS and SIPS software.

Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wave-generated currents. Data and samples were acquired using the Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG. This folder contains the images derived from benthic samples taken on the surveys GA0312, GA0315 and GA0309 aboard HMS Kimbla. These images formed the first point of reference in identifying subsequent specimens to save wear and tear on the specimens put aside as reference material. Four phylum folders exist within the main folder: Annelida, Crustacea, Echinodermata and Mollusca. The crustacea folder contains further folders, breaking the images into finer groupings. Images of taxa that do not fit in the four phylum folders are loose in the main folder.

This resource contains a Local Moran's I grid of the bathymetry data for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The Local Moran's I grid of the bathymetry data was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority. This data measures Local Moran's I of the bathymetry data. The Local Moran's I indicates spatial autocorrelation within a local area. A large positve (negative) value of the Local Moran's I indicates positive (negative) spatial autocorrelation. A value close to zero indicates randomness or no spatial autocorrelation.

The Apollo Marine Park bathymetry survey was acquired by Deakin University Marine Mapping lab onboard the M/V Yolla during the period 07 January - 22 May 2021 using a Kongsberg EM2040C multibeam sonar system. The survey was completed as part of a contract with Parks Australia to map the shallow bathymetry in the Marine Park and an Our Marine Parks grant to extend the mapping within the park. The survey was led by Dr. Daniel Ierodiaconou (Deakin University). This dataset contains a 2m-resolution 32-bit floating point GeoTIFF file of the bathymetry in the study area, derived from the processed EM2040C bathymetry data, using CARIS HIPS and SIPS software. This dataset is not to be used for navigational purposes.

The Great North Channel Torres Strait Multibeam survey was acquired for the Australian Hydrographic Office (AHO) onboard the MV Offshore Guardian and MV Special Order during the period 04 February– 14 April 2021. This was a contracted survey conducted by Guardian Geomatics as part of the Hydroscheme Industry Partnership Program. The survey area encompasses the Great North East Channel of the Torres Strait located between the Stephens Island, Pearce Cay and Rennel Island, Queensland. Bathymetry data was acquired using a Kongsberg EM2040-07 and Norbit iWBMSh Stx 200-400 kHz and processed using CARIS HIPS & SIPS 11.3 processing software. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area. <BR>This dataset is not to be used for navigational purposes.

The Wilsons Promontory West Glennie and Refuge Cove bathymetry survey was acquired by Deakin University Marine Mapping lab onboard the M/V Yolla on 18 June 2016 using a Kongsberg EM2040c. This survey was part of a Parks Victoria project to assess the impact of the Wilsons Promontory Marine National Park on southern rock lobster populations. These data were collected to provide habitat information in the sampling locations outside the park where no multibeam data existed. The survey was led by Dr. Daniel Ierodiaconou (Deakin University). This dataset contains a 2m-resolution 32-bit floating point GeoTIFF file of the bathymetry in the study area, derived from the processed EM2040C bathymetry data, using CARIS HIPS and SIPS software.

This resource includes bathymetry data for Elizabeth and Middleton 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 & Antarctic Studies (University of Tasmania), NSW Department of Primary Industries, University of Sydney (Centre for Field Robotics) and Parks Australia. 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 the 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 Vehicle (AUV Sirius), sediment samples (grab) and imagery of demersal fish communities by baited remote underwater video (BRUV). This dataset comprises two bathymetry grids derived from multibeam sonar data gridded at 5 m spatial resolution, covering a combined area of 312 km2 including the transit.

The Austrea1 bathymetry survey, GA-0222 was acquired by Geoscience Australia onboard the IFREMER N/O L'Atalante from the 17th of December 1999 to the 11th of January 2000 using a Simrad EM12 Dual sonar system. The main objectives of the shipboard program are to collect seabed and sub- bottom data in specific areas off southeast Australia for marine research (geological and biological), assessment of resource potential, regional marine zone planning and management, and to support Australia's claims under UNCLOS and to map the deep water part of a marine protected area in the Great Australian Bight (GAB). This dataset contains a 100m resolution 32-bit geotiff of the Austrea1 survey, produced from the processed EM12D bathymetry data of the survey area using the CARIS HIPS and SIPS software.
