Multiproxy assessment of the western equatorial Pacific hydrography during the last 30 kyr

Creator:

de Garidel-Thoron, Thibault, Rosenthal, Yair, Beaufort, Luc, Bard, Edouard, Sonzogni, Corinne, and Mix, Alan C.

Abstract:

Sea surface temperature (SST) and salinity of the Western Pacific Warm Pool (WPWP) reflect global climate effects such as the El Niño–Southern Oscillation phenomenon. However, reconstructions of past changes in the WPWP from the geologic record vary depending on the specific proxy record used. Here we develop a multiproxy record...

Vanadium in foraminiferal calcite as a tracer for changes in the areal extent of reducing sediments

Creator:

Hastings, David W., Emerson, Steven R., and Mix, Alan C.

Abstract:

We have used the vanadium concentration in cleaned foraminiferal calcite as a tracer of seawater V changes in the past. Since the benthic flux of vanadium is sensitive to the redox potential of sediments, changes in the vanadium concentration of seawater should be a reflection of changes that control the...
