University of Washington Quaternary Isotope Laboratory Retrospective
The Quaternary Isotope Laboratory (QIL) at the University of Washington was launched in 1969 and directed by Minze Stuiver until his retirement in 1998. Here we review some of the scientific work undertaken in the QIL and the memories of some of Minze’s former students and colleagues
High-Precision Radiocarbon Age Calibration for Terrestrial and Marine Samples
Single-year and decadal radiocarbon tree-ring ages are tabulated and discussed in terms of 14 C age calibration. The single-year data form the basis of a detailed 14 C age calibration curve for the cal ad 1510–1954 interval (“cal” denotes calibrated). The Seattle decadal data set (back to 11,617 cal BP, with 0 BP = ad 1950) is a component of the integrated decadal INTCAL98 14 C age curve (Stuiver et al. 1998). Atmospheric 14 C ages can be transfo…
Is There Evidence for Solar Forcing of Climate in the Gisp2 Oxygen Isotope Record?
Changes in solar constant over an 11 yr cycle suggest a certain, but limited, degree of solar forcing of climate. The high-resolution climate (oxygen isotope) record of the Greenland GISP2 (Greenland Ice Sheet Project 2) ice core has been analyzed for solar (and volcanic) influences. The atmospheric 14 C record is used as a proxy of solar change and compared to the oxygen isotope profile in the GISP2 ice core. An annual oxygen isotope profile is …
The Gisp2 δ18O Climate Record of the Past 16,500 Years and the Role of the Sun, Ocean, and Volcanoes
Measured 18O/16O ratios from the Greenland Ice Sheet Project 2 (GISP2) ice core extending back to 16,500 cal yr B.P. provide a continuous record of climate change since the last glaciation. High-resolution annual 18O/16O results were obtained for most of the current millennium (A.D. 818-1985) and record the Medieval Warm Period, the Little Ice Age, and a distinct 11-yr 18O/16O cycle. Volcanic aerosols depress central Greenland annual temperature …
Sun, ocean, climate and atmospheric 14CO2
Solar (heliomagnetic), geomagnetic and oceanic forcing all play a role in atmospheric 14 CO 2 change. Here we assign the variance associated with certain periodicities in a single year (0-450 cal. BP) and a Holocene bidecadal (0-11400 cal. BP) 14 CO 2 record to specific forcing factors. In the single-year time series the variance in the 2-6-year periodicity range is attributable to El Niño-Southern Oscillation (ENSO) ocean perturbations. A 10-11-…
Modeling Atmospheric 14 C Influences and 14 C Ages of Marine Samples to 10,000 BC
The detailed radiocarbon age vs. calibrated (cal) age studies of tree rings reported in this Calibration Issue provide a unique data set for precise 14 C age calibration of materials formed in isotopic equilibrium with atmospheric CO 2 . The situation is more complex for organisms formed in other reservoirs, such as lakes and oceans. Here the initial specific 14 C activity may differ from that of the contemporaneous atmosphere. The measured remai…
Climatic, Solar, Oceanic, and Geomagnetic Influences on Late-Glacial and Holocene Atmospheric 14 C/ 12 C Change
Late-glacial and Holocene 14 C/ 12 C ratios of atmospheric CO 2 vary in magnitude from a few per mil for annual/decadal pertubations to more than 10% for events lasting millennia. A data set illuminating 10- to 10 4 -yr variability refines our understanding of oceanic (climatic) versus geomagnetic or solar forcing of atmospheric 14 C/ 12 C ratios. Most of the variance in the Holocene atmospheric 14 C/ 12 C record can be attributed to the geomagne…
Compilation of Isotopic Dates from Antarctica
This compilation of radiometric data from Antarctica contains abstracted information from 400 publications, resulting in nearly 2500 separate entries. Each entry, or “date listing”, gives basic information of the sample site as well as the dating method and the age(s) of the sample analysed. The date list differs from those routinely published in Radiocarbon because we included not only radiocarbon but all dating methods
