Spatial Distribution Of Sediment Particles And Trace Element Pollution Within Gunnamatta Bay, Port Hacking, Nsw, Australia, Yasir M. Alyazichi, Brian G. Jones, Errol J. Mclean

A combination of geochemical analysis and hydrodynamic measuring has been established in order to provide an explanation for the spatial distribution of both sediment particles and trace element pollution Gunnamatta Bay, NSW, Australia. Fifty nine samples of surface sediment were collected to determine the spatial concentrations of trace elements in the bay. Moreover, current track pathways and velocities have been measured in the bay. The distribution of trace elements such as chromium, nickel, copper, zinc, arsenic and lead had similar patterns in surface sediments. Trace element pollution is concentrated along the current trajectory in the inner part of the bay, …

Most organic geochemical studies of the Permian-Triassic mass extinction (PTME) have utilised marine sections, and the boundary is readily identified by a negative carbon isotope excursion. It is now well understood from various locations around the world that the marine ecosystem collapse is accompanied by biomarker evidence for photic zone euxinia, including isorenieratane, crocetane and 2,3,6-aryl isoprenoids (e.g. Grice et al., 2005). Far fewer studies have been carried out on non-marine PTME sections, and in particular no biomarker studies have been carried out on Australian sections, despite there being extensive Permian and Triassic sequences in eastern Australia, notably in the …
