Sediment Core Analysis Timor Sea Voyage SS06/2005

In June 2005, the Southern Surveyor Research Vessel commenced a trip to the Timor Sea region. This dataset contains 9 sediment cores and grab samples analysis collected on this voyage. This dataset relates to the objectives (as outlined in the Voyage Summary SS06/2005):

  1. Discover seeps of methane, oil, and brines on the seafloor, using wheelhouse sounder showing bubble plumes, seismic transects, swath mapping, surface and near bottom water sampling, and sediment coring tools. Gas chromatographic measurements of methane in water will be done in the ship laboratory.
  2. Obtain sediment cores from soft and hard bottom seafloor, and subsample the cores carefully for hydrocarbon and inorganic chemical measurements, and preserve samples for analyses in our home laboratories.
  3. Obtain samples of relict and living biota from the seafloor in association with submarine seeps, using sled dredges, rock dredges, Smith-MacIntyre Grab, and near-bottom water samples.

Chemical analysis for organic and inorganic carbon, N P and other elements were undertaken to estimate the rate of sediment accumulation, trace elements, geochemical composition of sediment and burial rate of organic and carbonate carbon.

Further information and data regarding this voyage have been archived within the CSIRO Marine and Atmospheric Research Data Centre, including data from ADCP deployments, CTD Profiles, Hydrology, Underway and Multibeam echosounder data.
