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

The carbonic system distribution and fluxes in the NE Atlantic during spring 1991
TL;DR: In this paper, the potential of the North Atlantic as a sink for atmospheric CO2 was investigated by studying the carbonic system using data obtained during the spring of 1991, and the air-sea flux was related to chlorophyll and other environmental variables, and regeneration of carbon in the mid-ocean was studied by examining vertical sections representative of the study area.

Chemical enhancement of the CO2 gas exchange at a smooth seawater surface
Joachim Kuss,Bernd Schneider +1 more
TL;DR: In this article, the authors quantify the chemical enhancement of CO2 gas exchange and its dependency on turbulence and pH, and show that chemical enhancement was only observed at low turbulence, which corresponded to k values of 2.5-4 cm h−1.

Longitudinally different variations of lower tropospheric carbon dioxide concentrations over the North Pacific Ocean
TL;DR: In this article, the seasonal CO 2 cycle was most enhanced at high latitudes and decreased gradually going southward with a phase delay; however, to the south the situation was reversed.

CO2 degassing from volcanic lakes
Agnes Mazot,Alain Bernard +1 more
TL;DR: In this article, the results of graphical statistical approach allow quantification of two degassing processes acting at the lake surface: one corresponding to CO2 fluxes resulting from rising bubbles and the second corresponding to equilibrium diffusion of dissolved CO2 at the water-air surface.

TL;DR: The SOLAS air-sea gas exchange experiment (SAGE) as mentioned in this paper was a multiple-objective study investigating gas transfer processes and the influence of iron fertilisation on biologically driven gas exchange in high-nitrate low-silic acid low-chlorophyll (HNLSiLC) Sub-Antarctic waters characteristic of the expansive subpolar zone of the southern oceans.

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.
