1 gru 2019 · Long-term measurements of CO 2 concentration and stable carbon and oxygen isotope ratio measurements based on hourly or minute scale (LAS) or periodic sampling (IRMS) are essential for understanding CO 2 dynamics in the environment.
23 paź 2020 · Carbon isotopes, 14 C and 13 C, in atmospheric CO 2 are changing in response to fossil fuel emissions and other human activities. Future simulations using different SSPs show continued changes in isotopic ratios that depend on fossil fuel emissions and, for 13 C, BECCS.
1 lip 2011 · With this purpose we will reevaluate the components of the Dole effect based on new observations on marine oxygen isotope effects, as well as, on recent information on isotopic effects of various O 2 consuming mechanisms including soil respiration.
25 paź 2018 · The carbon and oxygen isotope fractionations occurring during photodissociation of carbon monoxide (CO) by vacuum ultraviolet photons (91–107 nm) at 80 K were measured and the isotopic fractionations due to direct and indirect predissociation processes individually quantified.
14 lis 2002 · In summary: the oxygen isotopic signal in benthic forams is primarily an ice volume signal (and secondarily a temperature signal). Another contributing factor to variations in seawater oxygen isotopic composition is the internal distribution of oxygen isotopes in the ocean.
28 wrz 2021 · This Technical Review explains the use of and fractionation factors associated with hydrogen, carbon and oxygen isotopes in water cycle and CO2–carbonate–water system studies.
