Temperature and salinity reconstruction for sediment core GeoB3313-1, supplement to: Lamy, Frank; Rühlemann, Carsten; Hebbeln, Dierk; Wefer, Gerold (2002): High- and low-latitude climate control on the position of the southern Peru-Chile Current during the Holocene. Paleoceanography, 17(2), 1028
We reconstructed changes of temperature, salinity, and productivity within the southern Peru-Chile Current during the last 8000 years from a high-resolution sediment core recovered at 41°S using alkenones, isotope ratios of planktic foraminifera, biogenic opal, and organic carbon. Paleotemperatures...
