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

Influence of gas exchange coefficient parameterisation on seasonal and regional variability of CO2 air‐sea fluxes
TL;DR: The authors examined the consequences of using four exchange coefficient versus wind speed parameterisations on the air-sea CO2 flux estimation, using one year of satellite wind speed measurements at global scale.

Noble Gases in Ocean Waters and Sediments
TL;DR: Some of the more extensive applications of noble gases (mainly helium isotopes) to studies of oceanographic problems have been described in this paper, including the modern oceanic circulation, paleo-oceanography, hydrothermal and cold brine systems in the deep ocean, and ocean/atmosphere gas exchange.

Calcite precipitation instability under laminar, open-channel flow
Øyvind Hammer,Dag Kristian Dysthe,B. Lelu,B. Lelu,Halvor Lund,Halvor Lund,Paul Meakin,Paul Meakin,Bjørn Jamtveit +8 more
TL;DR: In this paper, a 2D numerical model for the growth of calcite from supersaturated aqueous solutions under laminar, open-channel flow conditions is presented, which couples solution chemistry, precipitation at solution/calcite interfaces, hydrodynamics, diffusion and degassing.

Modelling of Geochemical Tracers in the Ocean
TL;DR: In this paper, the basic mechanisms of marine biology and chemistry which influence the atmospheric concentration of carbon dioxide are embedded in the three-dimensional current field of an OGCM and modelled tracers are phosphate, alkalinity, oxygen, dissolved inorganic carbon, particulate organic carbon, and calcite.

Seasonal and regional comparison of oceanic and atmospheric dimethylsulfide in the northern North Pacific: Dilution effects on its concentration during winter
TL;DR: In this article, the seasonality of oceanic and atmospheric DMS might be explained by dilution effects due to strong mixing during winter, and the seasonal difference in the DMS budget in the ABL was assessed by the time series mass-balance model.

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.
