Journal ArticleDOI
Relationship between wind speed and gas exchange over the ocean
TL;DR: In this paper, the influence of variability in wind speed on the calculated gas transfer velocities and the possibility of chemical enhancement of CO2 exchange at low wind speeds over the ocean is illustrated using a quadratic dependence of gas exchange on wind speed.
Journal ArticleDOI

TL;DR: Using inorganic carbon measurements from an international survey effort in the 1990s and a tracer-based separation technique, the authors estimate a global oceanic anthropogenic carbon dioxide (CO2) sink for the period from 1800 to 1994 of 118 19 petagrams of carbon.

TL;DR: In this paper, the authors describe and synthesize data sets and methodology to quantify the five major components of the global carbon budget and their uncertainties, including emissions from land use and land-use change data and bookkeeping models.

TL;DR: In this article, a global mean distribution for surface water pCO2 over the global oceans in non-El Nino conditions has been constructed with spatial resolution of 4° (latitude) × 5° (longitude) for a reference year 2000 based upon about 3 million measurements of surface water PCO2 obtained from 1970 to 2007.

TL;DR: In this paper, the Wanninkhof dependence of the CO2 gas transfer velocity has been used to estimate the global ocean CO2 flux in the mean non-El Nino conditions for a reference year 1995.
