Pacific Alkenone Sea Surface Temperature Reconstruction
Entry ID: NOAA_NCDC_PALEO_2005-005

[ Update this Record ]

Summary
Abstract: Marine sediments from the Chilean continental margin are used to infer
millennial-scale changes in southeast Pacific surface ocean water properties
and Patagonian ice sheet extent since the last glacial period. Our data show a
clear "Antarctic" timing of sea surface temperature changes, which appear
systematically linked to meridional displacements in sea ice, westerly winds,
and the circumpolar current system. Proxy data for ice sheet changes show a
similar pattern as oceanographic variations offshore, but reveal a variable
glacier-response time of up to ~1000 years, which may explain some of the
current discrepancies among terrestrial records in southern South America.

This data set is the Alkenone-based Sea Surface Temperature Reconstruction.
Alkenone data is from ODP Site 1233.
