A key objective for which is to characterise the composition, abundance and distributions of benthic fauna (seabed animals) associated with volcanic seamounts, canyon and seep zone habitats in in ~1000-5000 m depth, within and adjacent to the Chevron lease areas in the GAB. Sediment samples were taken at 6 potential seep, 5 volcanic seamount, and 3 deep outcropping rock sites using the Integrated Coring Platform (ICP) and the Smith-MacIntyre grab. 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. The Smith-MacIntyre grab is a comparatively simple tool collecting sediments. Sediment samples were analysed ...
