| FR 01/97 [details] |
B. Opdyke (ANU) | Cruise FR 01/97 was undertaken to study water chemistry and sediment mineralogy off the Great Barrier Reef, plus microfossils and fossil pollen. Cruise objectives included to search for geochemical signals for shallow water sediment dissolution off the GBR; gravity core for Paleoceanographic research and sedimentary response to changing carbonate saturation state of the sea water with depth and to core the GBR lagoon off the Whitsundays where geophysical modelling of the post-glacial sea level rise predicts lacustrine sediment deposition (a paleo-lake about 11,000 bp). Survey methods included CTDs, grabs, gravity cores and underway instrumentation. Adequate core and water samples were obtained to achieve objectives. |
| FR 03/96 [details] |
B. Opdyke (ANU) | Cruise FR 03/96 was undertaken to determine the nature of sedimentation in the Northwest Shelf around the Rowley Shoals, Scott Reef and Ashmore Reef during the last glacial maximum. Survey methods included gravity and vibra cores, grabs, SCUBA dives, CTDs, ADCP and underway instrumentation. Data, water, sediments, coral and shell samples were collected for on board and laboratory analyses. |
