Recent variability of the global ocean carbon sink [PDF]

, 2014
We present a new observation-based estimate of the global oceanic carbon dioxide (CO2) sink and its temporal variation on a monthly basis from 1998 through 2011 and at a spatial resolution of 1×1.

An observing system simulation for Southern Ocean carbon dioxide uptake [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014
The Southern Ocean is critically important to the oceanic uptake of anthropogenic CO 2 . Up to half of the excess CO 2 currently in the ocean entered through the Southern Ocean. That uptake helps to maintain the global carbon balance and buffers transient climate change from fossil fuel ...

Ozone and haze pollution weakens net primary productivity in China [PDF]

, 2017
Atmospheric pollutants have both beneficial and detrimental effects on carbon uptake by land ecosystems. Surface ozone (O3) damages leaf photosynthesis by oxidizing plant cells, while aerosols promote carbon uptake by increasing diffuse radiation and ...

Increased Left Ventricular Stiffness Impairs Exercise Capacity in Patients with Heart Failure Symptoms Despite Normal Left Ventricular Ejection Fraction

Cardiology Research and Practice, 2011
Aims. Several mechanisms can be involved in the development of exercise intolerance in patients with heart failure despite normal left ventricular ejection fraction (HFNEF) and may include impairment of left ventricular (LV) stiffness.

Projected reversal of oceanic stable carbon isotope ratio depth gradient with continued anthropogenic carbon emissions

Communications Earth & Environment, 2022
Uptake of 13C-depleted anthropogenic carbon dioxide in the surface ocean may eliminate or reverse the natural vertical gradient in the isotopic composition of dissolved inorganic carbon in the ocean, analogous to events at the Paleocene-Eocene Thermal ...

Methods for Measuring Carbon Dioxide Uptake and Permanence: Review and Implications for Macroalgae Aquaculture

Journal of Marine Science and Engineering, 2023
Carbon dioxide removal (CDR) is gaining recognition as a necessary action in addition to emissions reduction to prevent some of the worst effects of climate change.

Towards understanding the variability in biospheric CO2 fluxes:Using FTIR spectrometry and a chemical transport model to investigate the sources and sinks of carbonyl sulfide and its link to CO2 [PDF]

, 2016
Understanding carbon dioxide (CO2) biospheric processes is of great importance because the terrestrial exchange drives the seasonal and interannual variability of CO2 in the atmosphere. Atmospheric inversions based on CO2 concentration measurements alone

Carbon Dioxide Uptake During Anaerobic Metabolism of Bovine Spermatozoa

Journal of Dairy Science, 1972
Abstract Anaerobic CO 2 uptake by bovine spermatozoa has been studied by direct manometric measurements with the Warburg respirometer. This uptake phenomenon requires spermatozoa or their components, pyruvate as substrate, NADH as a co-factor, and a CO 2 containing gas phase. The magnitude of the uptake was directly associated with available NADH in

The global carbon budget 1959-2011 [PDF]

, 2012
Accurate assessments of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere is important to better understand the global carbon cycle, support the climate policy process, and ...
