Survey InvestigatorDescription
SS 06/2005

G. Brunskill (AIMS) Southern Surveyor National Facility voyage SS200506.
Biogeochemical processes, effects and signatures of hydrocarbon and ground-water seepage within a tropical, carbonate-rich system: Australia's Timor Sea.
Voyage Objectives (from Voyage Plan)
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 nearbottom water samples.
4. Use the swath mapping and seismic tools on the ship to locate best sites for biological and chemical sampling of the water column and seafloor.
5. Measure the daily consumption and production of oxygen in the water column to estimate primary production and respiration. Also to sample the zooplankton, which consume the products of primary production.
6. Obtain drill cores of living and dead corals from the tops of shoal mounds, to measure the history of hydrocarbon abundance, and the age of the mound tops.
FR 02/2000

G. Brunskill (AIMS), C. Nittrouer + other Pis The following information is taken from the voyage plan:
This voyage aims to collect data for the TROPICS project for the south coast PNG Gulf of Papua rivers, where nearly all large river inputs are trapped in the mangroves and inner shelf. Collaborators are trying to measure all the components of a mass balance for river inputs, losses to the atmosphere and sedimentation, and export to oceanic circulation. Other aims will be mapping Holocene sediment thickness with high resolution seismic equipment, Kasten Coring and box coring sediments to estimate accumulation rate and sediment mixing depth, Kasten and box coring to obtain benthic biological samples, and for measurements of organic matter decomposition reactionsand, measuring the natural isotopes of radium in large volume samples of surface water to estimate the residence time of shelf water, and obtaining grab samples and Kasten Cores for geochemical mass balance research on trace elements and the biological elements in the Gulf of Papua.
FR 09/96

G. Brunskill (AIMS) including other PIs Cruise FR 09/96 was undertaken to study hydrocarbons in the region of Exmouth Gulf, shelf, slope and Exmouth Plateau. Survey methods included grab and core sampling, sediment trap and current meter arrays, SeaStar rigs, primary production profiles, large volume water sampling, ADCP, CTDs and underway instrumentation. Surface sediment sampling for microbiological experiments were also conducted. Data, sediment and water samples were collected for on board and laboratory analyses.
Moorings previously deployed in June 96 from AIMS ships were retrieved, serviced and redeployed successfully with the exception of the Scott Reef mooring.
FR 03/93

G. Brunskill (AIMS) Cruise FR 03/93 (also known as PASMADES) was undertaken to identify and measure the flux of detritus exported from Papuan rivers bordering the Gulf of Papua and deposited on the adjacent continental margin, and to develop a carbon budget of the mineralisation and incorporation of the material into the food-chain. Survey methods included CTDs, sediment traps, grabs, box/Kastern coring, beam trawls and underway instrumentation. Biological, sediment and water samples were collected for on board and laboratory analyses. Analysis of the water samples included primary/bacterial production measurements, nutrient chemistry, chlorophyll, suspended sediments, trace metals, and radionuclide. Terrestrial/mangrove organic debris was also collected.
