Full description
Sediment cores at three locations were collected using a push corer by diving and a Vibecore-D corer on the research vessel RV Solander of Australian Institute of Marine Science in 2011, 2013 and 2014. The concentration profiles of 210Pb were determined through the measurement of 210Po in radioactive equilibrium at Edith Cowan University. The concentrations of 137Cs were determined by gamma-ray spectrometry (Canberra Be3830) with a relative counting efficiency of 35% and an energy resolution of 1.8 keV (at 1332 keV). Grain sizes were measured using a Malvern Mastersizer 2000F Laser Particle Sizer, after pretreated with 10% H2O2, 10% HCl and 0.05% (NaPO3)6 solution. The sterol contents were determined by GC (Agilent 7890 A) with an FID detector and a HP-1 column (50 m × 0.32 μm × 0.17 μm). Coverage: Median Latitude: -16.142400 * Median Longitude: 124.190500 * South-bound Latitude: -18.067000 * West-bound Longitude: 122.283000 * North-bound Latitude: -13.883000 * East-bound Longitude: 127.133000
