CCS - MV Bluefin 2017 V01 Smith McIntyre Grab Sediments

Project Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters. --o-- The Smith MacIntyre Grab is designed to collect ocean sediment with a sampling area of 0.1m sq. This grab is mounted on a stainless steel frame suspended from a pair of lowering cables (bridles) attached to the bucket arms. Springs activated by a trigger mechanism, released when the foot plates come into contact with the ocean floor, force the bucket jaws into the sediment in order to collect the sample. Safety features have been fitted to the grab to prevent the tripping mechanism from being triggered prematurely. Screens have also been fitted to the tops of the buckets, along with silicone flaps, to prevent sediment from being washed out during retrieval. CSIRO. Sediment samples were collected during BLU201701. The samples were sent from Hobart, TAS to Kensington, WA for analyses on 26 February 2018.
