NOAA/WDS Paleoclimatology - Alkenone paleotemperature estimates, d18O seawater data, and coarse fraction data from the Gulf of Alaska spanning the past 18,000 years

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2017-07-17T00:00:00.000+00:00
This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Paleoceanography. The data include parameters of paleoceanography with a geographic location of Gulf Of Alaska, North Pacific Ocean. The time period coverage is from 18170 to 400 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.
