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 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.
17 sty 2018 · The 13 C/ 12 C ratio of C 3 plant matter is thought to be controlled by the isotopic composition of atmospheric CO 2 and stomatal response to environmental conditions, particularly mean...
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...
22 wrz 2022 · This paper outlines the use of stable isotopic carbon tracers to distinguish the sources and influences of waters around the western North Pacific to provide further constraints on physical, biological, and anthropogenic processes.
7 sty 2008 · Much is known about the processes that regulate the carbon isotopic composition (δ 13 C) of leaf, plant, and ecosystem carbon pools and of photosynthetic and respiratory carbon dioxide (CO 2) fluxes. In this review, systematic patterns and mechanisms underlying variation in δ 13 C of plant and ecosystem carbon pools and fluxes are described.
18 lut 2021 · Key Points. The ratio of δ13 C DIC to phosphate is revised to −1.01‰, consistent with a carbon to phosphate ratio of organic matter of 124 ± 10. Global circulation impacts deep ocean δ13 C DIC via the north to south proportionality of water masses and their preindustrial δ13 C DIC values.
