This record describes the sediment data collected from the Marine National Facility RV Investigator Event Voyage IN2015_E02, departing Hobart on the 7th April and returning to Hobart on the 14th April, 2015. The primary voyage objective was to deploy a specific sub-set of sampling equipment related to benthic biology, to establish processes, procedures and work flows in places such as the rear deck and sample processing laboratories. The primary equipment trialled was the MNF Deep Tow Camera, MNF Beam trawl, MNF Benthic (Sherman) Sled, and MNF Smith-McIntyre Grab, and the CSIRO-supplied Integrated Corer Platform (ICP), DeepBRUVs lander, and fishing dropline. The Integrated Coring Platform ( ICP) combines a number of technologies to maximise sampling in a single deployment. The ICP is built around a 6 barrel corer (KC, Denmark) and together with its central electronics module integrates cameras (cable, seafloor and corer views), CTD (SBE37IDO), altimeter, 120KHz scientific echo-sounders, Niskin bottles and hydrocarbon sensor suite. Sensor data is delivered in real time to the surface via fibre optic deployment cable. Video data from the ICP cameras includes imagery of seafloor types and mid-water biota during the up/down casts, refer to related marlin record for video data access. This metadata record describes the sediment collection using the grab and ICP taken inside the Huon Commonwealth Marine Reserve at 5 depth strata (100m, 200m, 500m, 1000m and 2000m) and on Patience seamount. Sediment samples were collected for chemical (CSIRO Energy), grainsize and composition (SARDI) analyses; surface water was also collected for PAH (polycyclic aromatic hydrocarbons ) analysis by NMI (National Measurements Institute). Bulk samples of sediments were elutriated for macrofauna analysis (University of Adelaide).
