Global or regional? Constraining the origins of the middle Bambuí carbon cycle anomaly in Brazil
(2020-09-15)
The Ediacaran-Cambrian Bambuí Group in Brazil records an anomalously positive excursion in carbonate carbon isotopes (δ13Ccarb) with a sustained plateau of ca. +15‰ (aka the Middle Bambuí Excursion–MIBE). Considering that ...
Benthic foraminiferal stable carbon isotope constraints on deglacial ocean circulation and carbon-cycle changes
(Läderach AG, 2019-11)
How does deep-ocean circulation influence atmospheric CO2 across deglacial transitions? Although biogeochemical and physical processes complicate interpretation of foraminiferal stable carbon isotope data, these complications ...
Methane and carbon dioxide seasonal cycles at urban Brazilian inland sites
(Kluwer Academic Publ, 2004-02-01)
Methane and carbon dioxide seasonal cycles during years 1998 and 1999 at two Brazilian urban and inland sites are presented. The mixing ratio averages over the studied period of time were 1.80 ppm CH4 and 384.7 ppm CO2. A ...

Animals and the zoogeochemistry of the carbon cycle
(Amer Assoc Advancement Science, 2018-12-07)
Predicting and managing the global carbon cycle requires scientific understanding of ecosystem processes that control carbon uptake and storage. It is generally assumed that carbon cycling is sufficiently characterized in ...
Ecosystem services and biogeochemical cycles on a global scale: valuation of water, carbon and nitrogen processes
(Elsevier Sci LtdOxfordInglaterra, 2011)
A lake classification concept for a more accurate global estimate of the dissolved inorganic carbon export from terrestrial ecosystems to inland waters
(Springer, 2018-03)
The magnitude of lateral dissolved inorganic carbon (DIC) export from terrestrial ecosystems to inland waters strongly influences the estimate of the global terrestrial carbon dioxide (CO2) sink. At present, no reliable ...
Responses and feedbacks of coupled biogeochemical cycles to climate change: Examples from terrestrial ecosystems
(Ecological Society of America, 2011-02)
The biogeochemical cycles of carbon (C), nitrogen (N), and phosphorus (P) are fundamental to life on Earth. Because organisms require these elements in strict proportions, the cycles of C, N, and P are coupled at molecular ...
Carbon-cycle changes during the Toarcian (Early Jurassic) and implications for regional versus global drivers of the Toarcian oceanic anoxic event
(Elsevier Science, 2020-10)
The Early Jurassic Toarcian oceanic anoxic event (T-OAE) is characterized by an extinction event, a major sea-level rise, enhanced marine primary productivity, elevated seawater temperatures, widespread deposition of ...
