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).
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...
1 paź 2019 · We discuss carbon isotope ratios as tracers in atmospheric carbon dioxide and methane, along with DIC, DOC, and methane in ocean and pore waters. We then address carbon isotope ratios of organic matter and foraminiferal carbonate in relationship to their ambient sea-water isotope composition and their utility as non-conservative proxies.
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 ...
