California Current Reconstruction from Benthic Isotopes and Alkenone Temperatures

Abstract: [from NOAA/NGDC/WDC-A Paleoclimatology]
Time series of alkenone unsaturation indices gathered along the
California margin reveal large (40 to 80C) glacial-interglacial
changes in sea surface temperature (SST) over the past 550,000
years. Interglacial times with SSTs equal to or exceeding that of the
Holocene contain peak abundances in the pollen of redwood, the
distinctive component of the ... View entire text
