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

Physical controls on CH 4 emissions from a newly flooded subtropical freshwater hydroelectric reservoir: Nam Theun 2
C. Deshmukh,C. Deshmukh,Dominique Serça,Claire Delon,R. Tardif,M. Demarty,C. Jarnot,Yves Meyerfeld,Vincent Chanudet,Pierre Guédant,W. Rode,Stéphane Descloux,Frédéric Guérin +12 more
TL;DR: In this paper, the authors measured independently CH4 ebullition and diffusion in the footprint of an eddy covariance system (EC) measuring CH4 emissions in the Nam Theun 2 Reservoir, a recently impounded (2008) subtropical hydroelectric reservoir located in the Lao People's Democratic Republic (PDR), Southeast Asia.

The distribution of light nonmethane hydrocarbons over the mid-Atlantic: Results of the Polarstern cruise ANT VII/1
TL;DR: In this article, the latitudinal distributions of several nonmethane hydrocarbons were measured over the Atlantic between 45°N and 30°S by in-situ gas chromatography.

Methane sources, sinks and fluxes in a temperate tidal Lagoon: The Arcachon lagoon (SW France)
Jonathan Deborde,Pierre Anschutz,Frédéric Guérin,Frédéric Guérin,Dominique Poirier,Danielle Marty,Guy Boucher,Gérard Thouzeau,Mathieu Canton,Gwenaël Abril +9 more
TL;DR: The Arcachon lagoon is a 156 km 2 temperate mesotidal lagoon dominated by tidal flats (66% of the surface area) and the methane sources, sinks and fluxes were estimated from water and pore water concentrations, from chamber flux measurements at the sediment-air (low tide), sediment-water and water-air interfaces, and from potential oxidation and production rate measurements in sediments as discussed by the authors.

Greenhouse gas emissions (CO2, CH4, and N2O) from several perialpine and alpine hydropower reservoirs by diffusion and loss in turbines
TL;DR: In this paper, the first results of greenhouse gas emissions from reservoirs at high elevations in the Alps were investigated, and the results indicate reservoirs from subalpine/alpine regions to be only minor contributors of greenhouse gases to the atmosphere compared to other reservoirs.

Temporal and spatial variations of dimethylsulfide (DMS) and dimethylsulfoniopropionate (DMSP) in the East China Sea and the Yellow Sea
TL;DR: In this paper, the temporal and spatial distributions of DMS and its precursor DMSP were determined in the East China Sea and the Yellow Sea during June-July, 2006 and January-February, 2007.

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.
