This record describes the operations undertaken and geological sample data collected on the Fugro vessel REM Etive Charter Voyage RE2017_C01, titled "Great Australian Bight (GAB) Deep Water Geological and Benthic Ecology Program." This charter voyage took place from Hobart to Adelaide between the 13th of March and the 6th of April, 2017. The voyage, undertaken over 25 days, was a great success with 33 researchers from several research organisations and the vessel crew undertaking 40 operations over 5 target areas in water depths ranging from 1000 m to 3000 m. The voyage deployed a diverse range of instrumentation fully utilising the REM Etive capabilities which included two work class Remotely Operated Vehicles (ROV) and a Sea Floor Drill. This also involved the deployment of these 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 54 pieces of rock were individually collected by the ROVs, plus 162.98m of core drilled. This record contains data recorded during the survey including the activity log, observation log, operation log, a log of general photographs taken, descriptions of geology collected, biology catch locations, details of samples taken for analysis and the daily "Trip" details which defined the daily reporting periods. The Seafloor Drill 80mm diameter X 1m long Core sections were split and sampled for geochemical analysis. Remainders of the cores have been archived. Sampled half of the core at room temperature at the Perth Core Library, 37 Harris Street, Carlisle, WA 6101 phone +61 8 9470 0305. Images or documents of geological samples can be accessed and downloaded via the Distribution links below.

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.

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.
