This record describes the geological sample 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 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. 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 1.36 tons of rock and 15.2 m of sediment core were collected. This record contains data from the analysis of geological samples collected. Documents and files of geological sample analyses can be accessed and downloaded via the Distribution links below.
