  • Insights into Growth, Ring Formation and Maximum Ages of Brazil Nut Trees ( Bertholletia excelsa ) Using 14 C Dating and Tree-Ring Analysis

    Open AccessVictor Lery Caetano Andrade, Charles R Clement et al.ARTICLERadiocarbon2024Cited by: 1References: 79

    The Brazil Nut tree ( Bertholletia excelsa , Lecythidaceae) is a species of considerable historical, economic and ecological importance in South America. Radiocarbon dating indicates some individuals can live from hundreds to more than 1000 years, which means they have the potential to reconstruct deep time growth patterns and their relationship to anthropogenic management or climate change from pre-colonial to present times. However, age estimat…

  • Vertical pattern of organic matter decomposability in cryoturbated permafrost-affected soils

    Open AccessChristian Beer, Christian Knoblauch et al.ARTICLEEnvironmental Research Letters2022

    Permafrost thaw will release additional carbon dioxide into the atmosphere resulting in a positive feedback to climate change. However, the mineralization dynamics of organic matter (OM) stored in permafrost-affected soils remain unclear. We used physical soil fractionation, radiocarbon measurements, incubation experiments, and a dynamic decomposition model to identify distinct vertical pattern in OM decomposability. The observed differences refl…

  • Persistence of soil organic matter as an ecosystem property

  • Blank Assessment for Ultra-Small Radiocarbon Samples

    Open AccessGuaciara M Santos, John R Southon et al.ARTICLERadiocarbon2010Cited by: 22References: 26

    The Keck Carbon Cycle AMS facility at the University of California, Irvine (KCCAMS/UCI) has developed protocols for analyzing radiocarbon in samples as small as ∼0.001 mg of carbon (C). Mass-balance background corrections for modern and 14 C-dead carbon contamination (MC and DC, respectively) can be assessed by measuring 14 C-free and modern standards, respectively, using the same sample processing techniques that are applied to unknown samples. …

  • Methods of Separating Soil Carbon Pools Affect the Chemistry and Turnover Time of Isolated Fractions

    Open AccessCristina Castanha, Susan Trumbore et al.ARTICLERadiocarbon2008References: 35

    A variety of physical and chemical techniques are used to fractionate soil organic matter, but detailed comparisons of the different approaches and tests of how separation methods influence the properties of isolated organic matter pools are lacking. In this case study based on A horizon samples of 2 California coniferous forests soils, we 1) evaluate the effects of root removal and ultrasonic dispersion on the properties of the -3 light fraction…

  • The southwest Indian Monsoon over the last 18 000 years

    Open AccessJonathan T Overpeck, Jonathan Overpeck et al.ARTICLEClimate Dynamics1996

  • Radiocarbon Dating of Soil Organic Matter

    Open AccessYang Wang, Ronald Amundson et al.ARTICLEQuaternary Research1996

    Radiocarbon ages of soil organic matter are evaluated with a model which incorporates the dynamics of the 14 C content of soil organic matter. Measured 14 C ages of soil organic matter or its fractions are always younger than the true ages of soils due to continuous input of organic matter into soils. Differences in soil C dynamics due to climate or soil depth will result in significantly different 14 C signatures of soil organic matter for soils…

  • Lithium Contamination in AMS Measurements of 14 C

    Open AccessD H Loyd, J S Vogel et al.ARTICLERadiocarbon1991Cited by: 5References: 5

    High count rates of lithium ions in an AMS measurement system for 14 C were traced to the lithium content in the quartz tubes used in the graphitization of the samples. The lithium contamination was nearly eliminated by the use of borosilicate glass reaction tubes at a lower reaction temperature. The ion beam current and the measurement precision of the isotope ratio were not affected

  • Accelerator Mass Spectrometric Radiocarbon Measurements on Foraminifera Shells from Deep-Sea Cores

    Open AccessWallace S Broecker, Mieczyslawa Klas et al.ARTICLERadiocarbon1990Cited by: 4References: 11

    Radiocarbon ages determined by the AMS method on hand-picked foraminifera shells are reported. The results allow estimates of the ventilation rate of the deep Atlantic and Pacific Oceans during glacial time. They also extend our knowledge of the chronology of events associated with the transition from full glacial conditions ca 15,000 years ago to full interglacial conditions ca 8000 years ago. This and the previous lists (Broecker et al 1988c) c…

  • Anomalous AMS Radiocarbon Ages for Foraminifera from High-Deposition-Rate Ocean Sediments

    Open AccessWallace S Broecker, Susan Trumbore et al.ARTICLERadiocarbon1989Cited by: 3References: 10

    Radiocarbon ages on handpicked foraminifera from deep-sea cores are revealing that areas of rapid sediment accumulation are in some cases subject to hiatuses, reworking and perhaps secondary calcite deposition. We present here an extreme example of the impacts of such disturbances. The message is that if precise chronologies or meaningful benthic planktic age differences are to be obtained, then it is essential to document the reliability of radi…
