TLDR
In this article, the basic equations governing air-sea gas exchange are given, then a review of some models proposed to describe the gas transfer process is given, and experimental approaches through both laboratory (principally using wind/water tunnels) and field measurements are summarized.Abstract:
In this chapter we attempt to present a brief introduction to the subject of air-sea gas exchange First the basic equations governing such exchange are given, then a review of some models proposed to describe the gas transfer process Following this, experimental approaches through both laboratory (principally using wind/water tunnels) and field measurements are summarised Finally, we present what seems to us to be the best current synthesis of the wind tunnel and field results for the prediction of gas exchange rates across the sea surfaceread more

TL;DR: In this paper, the authors use continuous observations from 10 European stations (including 5 tall towers) for CH4 and 9 continuous stations for N2O, complemented by additional European and global discrete air sampling sites.

Long‐term variability of the terrestrial and oceanic carbon sinks and the budgets of the carbon isotopes 13C and 14C
Fortunat Joos,Michele Bruno +1 more
TL;DR: The long-term variability in the terrestrial and oceanic uptake of anthropogenic carbon is investigated in this article, where an inverse method called double deconvolution is applied for the last 200 years.

Nitrous oxide in the Changjiang (Yangtze River) Estuary and its adjacent marine area: Riverine input, sediment release and atmospheric fluxes
TL;DR: In this article, the authors measured the dissolved nitrous oxide (N2O) in the waters of the Changjiang (Yangtze River) Estuary and its adjacent marine area during five surveys covering the period of 2002-2006.

TL;DR: In this paper, three asymptotes are identified for gas exchange mediated by high void-fraction bubble plumes and a semi-empirical parameterization of bubble-mediated gas transfer is devised on the basis of these parameters, which describes the dependence of the overall transfer velocity on plume properties and molecular properties of the gas.

Simultaneous mooring-based measurements of seawater CO2 and O2 off Cape Hatteras, North Carolina
TL;DR: In this article, the correlation between CO and 0, indicates that biological and advective processes dominated the gas variability, with small or insignificant fluxes due to air-sea exchange, vertical eddy diffusion, and carbonate dissolution or formation.

Gas exchange rates between air and sea
TL;DR: In this article, the average film thickness for the world ocean based on the distribution of natural radiocarbon, bomb-produced radioccarbon, and radon are in good agreement, and Radon data from the BOMEX area and from station PAPA lend support to Kanwisher's suggestion that gas exchange rates should vary in proportion to the square of the wind velocity.

Vollständige Darstellung der turbulenten Geschwindigkeitsverteilung in glatten Leitungen
TL;DR: From experimental investigations of turbulent exchange of momentum a formula is derived for the velocity of turbulent flow in tubes and pipes in this paper, which gives a complete representation of the velocity distribution, i. e. it holds good close to the wall as well as in the core of the flow.
