Weathering assessment in the Achala Batholith of the Sierra de Comechingones, Córdoba, Central Argentina. II: Major hydrochemical characteristics and carbon dynamics
(Springer Verlag Berlín, 2016-01)
La Trucha is a granitic, second-order catchment (~1.9 km2, average slope 5%) placed at ~1400 m elevation in the Sierra de Comechingones (Argentina, 31°54´S, 64°45´W; 31°53´, 64°44´W). The main geochemical characteristics ...
Towards a better understanding of reservoir carbon cycling: drawdown emissions and sequestration in sediments of Chapéu D’uvas reservoir
(Universidade Federal de Juiz de Fora (UFJF)BrasilICB – Instituto de Ciências BiológicasPrograma de Pós-graduação em EcologiaUFJF, 2020)
Fluvial organic carbon cycling regulated by sediment transit time and mineral protection
(Nature Publishing Group, 2021-11)
Rivers transfer terrestrial organic carbon (OC) from mountains to ocean basins, playing a key role in the global carbon cycle. During fluvial transit, OC may be oxidized and emitted to the atmosphere as CO2 or preserved ...
Air-sea disequilibrium enhances ocean carbon storage during glacial periods
(American Association for the Advancement of Science, 2019-06-18)
The prevailing hypothesis for lower atmospheric carbon dioxide (CO2) concentrations during glacial periods is an increased efficiency of the ocean’s biological pump. However, tests of this and other hypotheses have been ...
A First Intercomparison of the Simulated LGM Carbon Results Within PMIP-Carbon: Role of the Ocean Boundary Conditions
(John Wiley & Sons Inc., 2021-10)
Model intercomparison studies of coupled carbon-climate simulations have the potential to improve our understanding of the processes explaining the (Formula presented.) drawdown at the Last Glacial Maximum (LGM) and to ...
Plateaus and jumps in the atmospheric radiocarbon record: Potential origin and value as global age markers for glacial-to-deglacial paleoceanography, a synthesis
(Copernicus Publications, 2020-12)
Changes in the geometry of ocean meridional overturning circulation (MOC) are crucial in controlling past changes of climate and the carbon inventory of the atmosphere. However, the accurate timing and global correlation ...
Paleosalinity determination in ancient epicontinental seas: A case study of the T-OAE in the Cleveland Basin (UK)
(Elsevier Science, 2020-02)
The Early Jurassic Toarcian oceanic anoxic event (T-OAE) was marked by deposition of organic-rich sediments and a pronounced negative carbon-isotope excursion across the Northwest European Sea (NWES), representing a signal ...
Ecogenomics and Adaptation Strategies of Southern Ocean Viral Communities
(2021)
The Southern Ocean (SO) represents up to one-fifth of the total carbon drawdown worldwide. Intense selective pressures (low temperature, high UV radiation, and strong seasonality) and physical isolation characterize the ...
