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 gru 2019 · The stable isotopes of carbon (δ 13 C) track changes in photosynthesis, respiration, organic matter decomposition and anthropogenic fuel emission inputs (e.g., McDowell et al., 2008), while the oxygen isotopes of water (δ 16 O and δ 18 O) contain information on the linkages between the carbon and water cycles (Dawson and Simonin, 2011).
17 sty 2018 · Atmospheric effects must be taken into account when interpreting terrestrial stable carbon isotopes, with important implications for past environments and climates, and understanding plant ...
28 wrz 2021 · Stable isotopes of hydrogen, carbon and oxygen are used to investigate numerous physical and chemical processes in the water and inorganic carbon cycles. Measuring and comparing natural...
Stable carbon isotope (δ 13 C) values are important indicators in carbon cycling, which can be used to qualitatively or quantitatively trace carbon sources, indicate carbon cycling processes, and determine end-members of the supply (Chen and Wang, 2012; Fan et al., 2020).
1 paź 2019 · Here we review the application of stable carbon isotope ratios in ocean water and biogenic carbonates as proxies in paleoceanography, including the atmospheric and sedimentary reservoirs oceanic carbon is in exchange with.
29 paź 2023 · Here, we report on in-situ non-destructive analyses of the C stable isotopic composition of CO2, applying a novel high-resolution Raman configuration on 42 high-density CO2 fluid inclusions in...
