This record describes the Towed Camera video stills taken on the RV Investigator Charter Voyage IN2015_C01, titled "Great Australian Bight (GAB) Deep Water Geological and Benthic Ecology Program." This charter voyage took place from Hobart to Port Lincoln between the 22nd of October and the 28th of November, 2015. The voyage, undertaken over 34 days, was a great success with 37 researchers from seven research organisations and the vessel crew undertaking 128 operations over 17 target areas in water depths ranging from 700 m to 5,437 m. 23 towed camera operations were undertaken across the survey extents in water depths less than 3000m. Video data was collected for each of these operations. The collection of stills extracted from the towed camera videos can be obtained by contacting the data librarians or the person listed as the individual responsible for the data.

This record describes the operations undertaken and geological sample data collected on the RV Investigator Charter Voyage IN2017_C01, titled "Great Australian Bight (GAB) Deep Water Geological and Benthic Ecology Program." This charter voyage took place from and to Hobart between the 11th and the 27th of April, 2017. The voyage, undertaken over 17 days, was a great success with 31 researchers from five research organisations and the vessel crew undertaking 47 operations over 6 target areas in water depths ranging from 200 m to 5,437 m. The voyage deployed a diverse and large collection of instrumentation fully utilising the Investigator capabilities. This involved the deployment of some of the equipment types significantly deeper than previous deployments either in Australia or worldwide. The data and samples collected significantly augment the sparse data and sample collections within the deep water GAB to date. Over 1.28 tons of rock were collected. This record contains data recorded during the survey including the activity log, observation log, operation log, acoustic contact log, a log of general photographs taken, descriptions of geology collected, biology catch locations, details of samples taken for analysis, project details and the daily "Trip" details which defined the daily reporting periods. Images or documents of geological samples and acoustic contacts can be accessed and downloaded via the Distribution links below. Physical pieces of rock collected on this voyage were sampled for geochemical analysis. Remainders of the rocks have been archived at the Perth Core Library, 37 Harris Street, Carlisle, WA 6101 phone +61 8 9470 0305.

This record describes the operations undertaken by an Autonomous Underwater Vehicle deployed from the FUGRO vessel Outer Limit in the Great Australian Bight (GAB). This charter voyage took place in November and December, 2015 as part of the Great Australian Bight (GAB) Deep Water Geological and Benthic Ecology Program, in conjunction with the IN2015_C01 survey. The voyage was a great success undertaking operations over 11 main target areas in water depths ranging from 900 m to 2,400 m. The AUV was equipped with a multibeam echo sounder, side scan sonar and sub bottom profiler, plus a HD camera system utilised during the small scale surveys over a further six selected areas within the 11 main target areas initially surveyed. High resolution bathymetry, backscatter and sidescan sonar data was collected along with photographic imagery of the seafloor. Track lines of the areas surveyed were also produced. A zip of the track lines (ESRI shapefiles) can be accessed and downloaded via the Distribution links below.

This record describes the Magnetometer data collected on the RV Investigator Charter Voyage IN2015_C01, titled "Great Australian Bight (GAB) Deep Water Geological and Benthic Ecology Program." This charter voyage took place from Hobart to Port Lincoln between the 22nd of October and the 28th of November 2015. The Magnetometer unit is used to measure magnetic field strength whilst towed through the water column. The magnetometer and BOB acquisition software was kindly provided on-loan by Geoscience Australia (GA). This dataset has been archived within the CSIRO O&A Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the voyage report for this voyage and data processing report. Please see documentation and data links. Raw data and partially processed data is available on request.

This record describes gravity data collected on RV Investigator research charter IN2015_C01, 'GAB deep water geological and benthic ecology program,' which departed Hobart on the 25 October and returned to Port Lincoln on the 28 November.
