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 · TDLAS measures the mixing ratios of stable isotopes of carbon dioxide in the air (e.g., the isotopologues, 12 C 16 O 2, 13 C 16 O 2 and 16 O 12 C 18 O) by comparing the infrared absorption of sample and reference gases in a specific absorption line of the spectrum (Santos et al., 2012).
28 wrz 2011 · The stable isotope ratios of atmospheric CO 2 (18 O/ 16 O and 13 C/ 12 C) have been monitored since 1977 to improve our understanding of the global carbon cycle, because...
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 ...
How much carbon dioxide is being absorbed into the ocean? Which parts of the ocean are absorbing the carbon dioxide? What other effects may this have, such as the ocean becoming more acidic 1? Answering these questions will help us to understand what might happen in the future as CO 2 levels continue to rise.
