| The UW's Quaternary Isotope Laboratory |
The Quaternary Isotope Lab of the University of Washington, under the direction
of Dr. Minze Stuiver, has been active in research involving both stable isotopes
(18O and 13C) and radiometric isotopes (14C).
18O, recovered from the permanent ice caps in Greenland and Antarctica,
is being used to construct a high-detail paleoclimate record going back to the
last interglacial period (>110000 years, in the case of the Greenland ice
core) and beyond (The Antarctic Taylor Dome core record exceeds 150000
years). The ratio of 18O/16O varies in approximate proportion
to the temperature at the time the original precipitation occured.
14C, as stored in tree rings, is being measured to accurately determine
the atmospheric 14C levels of the last 10000+ years. This is essential
in getting precise dates for historic and prehistoric materials. It can also be
used as a tool to indirectly determine solar activity and ocean circulation changes.
