23 paź 2020 · Key Points. 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.
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 · The stable carbon isotope (δ 13 C) of DIC, therefore, provides an important tracer for processes such as air-sea exchange, photosynthesis, and water dynamics in the ocean.
17 sty 2018 · The 13C/12C ratio of C3 plant matter is thought to be controlled by the isotopic composition of atmospheric CO2 and stomatal response to environmental conditions, particularly mean annual ...
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.
27 lip 2020 · A review of the organic carbon cycle explores the interactions between the Earth’s surface and deeper reservoirs, the expanding inorganic controls on the organic carbon cycle, and how these...
