Late Quaternary fluctuations of palaeoproductivity in the Murray Canyons area, South Australian continental margin

Gingele, Franz; De Deckker, Patrick

Description

Two sediment cores from the Murray Canyons area, south of Kangaroo Island, South Australia, were investigated for proxy-records to reconstruct past productivity of the surface waters in the area over the last 175 ka. The proxies used included concentrations of aragonite, low- and high-Mg calcite, total carbonate, total organic carbon, sulfur and δ13C of Globigerina bulloides. Cyclic increases in palaeoproductivity were observed to be in tune with insolation minima at 30°S. The atmospheric...[Show more]
