| SS 04/2005
|Dr P. T. Harris (Geoscience Australia)|| Southern Surveyor research voyage SS 4/2003 examined submerged reefs and benthic habitats in the Gulf of Carpentaria under the leadership of Dr. Peter T. Harris (Chief Scientist), Group Leader, Marine and Coastal Environment Group, Geoscience Australia.
This voyage is to follow up the discovery of three large patch reefs in the southern Gulf of Carpentaria during GA Survey 238 (SS03/2004) to examine the possibility of widespread reef occurrence in that region.
| SS 04/2003
|P. Harris (GA)||
To identify and quantify sediment sources, sinks and the Late Quaternary history of terrigenous sedimentation in the southern Gulf of Carpentaria,
To locate and map areas on the shelf characterised by modern terrigenous deposition,
To derive sediment budgets representative of the main depositional environments,
To date the onset of Holocene, pro-deltaic to distal deltaic/open shelf terrigenous sediment deposition as a function of distance from the coast,
To validate the GEOMAT sediment mobility model and its prediction of southward oriented maximum tidal current vectors adjacent to Mornington Island.
| FR 01/2002
|Dr Peter Harris (AGSO)||A zone of high tidal current energy across the northern margin of the Great Barrier Reef is hypothesised to be a cross-shelf corridor of sediment movement. It is proposed to conduct high resolution seabed mapping, seabed sampling and photography to identify mobile bed sediments and depositions. Key goals are to collect sufficient data to verify whether such cross-shelf transport is occurring, document benthic biological communities, collect sediment cores to extract a time series of cross-shelf terrigenous flux. The research is of relevance to environmental managers who require knowledge of the processes governing sediment dispersal and the distribution of biota in this environmentally sensitive and economically important geographic location.|
| FR 04/93
|P. Harris (Univ. of Sydney) & C. Pattiaratchi (Univ. of WA)||Cruise FR 04/93 was undertaken for a seismic survey and sampling program at the Fly River, northern Great Barrier Reef junction, Gulf of Papua. Cruise objectives included to identify high and low level patterns of sediment transport and deposition; to define major deposition environments, and to derive a conceptual model for sedimentation patterns. Survey methods included sediment grabs, surface and bottom water sampling for chlorophyll and suspended solids determination and CTD profiles (with dissolved oxygen, pH and transmissometer meters), piston/gravity cores, plankton trawls and underway instrumentation. Samples were collected for on board and laboratory analyses.|
