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
Seawater Radiocarbon Evolution in the Gulf of Alaska
Oceanic uptake and transport of bomb radiocarbon as 14 CO 2 created by atmospheric nuclear weapons testing in the 1950s and 1960s has been a useful diagnostic for determining the carbon transfer between the ocean and atmosphere. In addition, the distribution of 14 C in the ocean can be used as a tracer of oceanic circulation. Results obtained on samples collected in the Gulf of Alaska in the summer of 2002 provide a direct comparison with results…
Carbon isotope evidence for an abrupt reduction in grasses coincident with European settlement of Lake Eyre, South Australia
Stable carbon isotopes in emu eggshell (EES) reflect emu diets and consequently the vegetation available for food sources. At Lake Eyre, South Australia, isotopic data suggest that there has been a rapid and dramatic change in vegetation at some point over the last 200 years when compared with the rest of the Holocene. The proportion of C 4 plants in emu diets has been reduced by approximately 20% in response to an overall shift in C 4 /C3 biomas…
Woce Radiocarbon IV
The World Ocean Circulation Experiment, carried out between 1990 and 1997, provided the most comprehensive oceanic survey of radiocarbon to date. Approximately 10,000 samples were collected in the Pacific Ocean by U.S. investigators for both conventional large volume p counting and small volume accelerator mass spectrometry analysis techniques. Results from six cruises are presented. The data quality is as good or better than previous large-scale…
Woce AMS Radiocarbon I
AMS radiocarbon results from the World Ocean Circulation Experiment in the Pacific Ocean show dramatic changes in the inventory and distribution of bomb-produced 14 C since the time of the GEOSECS survey (8/73–6/74). Near-surface Δ 14 C values for the eastern portion of both the northern and southern subtropical gyres decreased by 25–50‰, with the change being greater in the north. Equatorial near-surface values have increased by ca. 25‰. Changes…
Atmospheric14C changes resulting from fossil fuel CO2 release and cosmic ray flux variability
Patterns of Atmospheric 14 C Changes
Natural atmospheric 14 C changes are caused by fluctuations in upper atmospheric 14 C production rates (Q) that are related to earth geomagnetic field variations and changes in solar wind magnetic shielding properties. Climate variability may also be responsible for some of the changes because it influences exchange rates of 14 C between the various terrestrial carbon reservoirs. Upper atmospheric 14 C production rates Q M , in at/sec cm 2 (earth…
