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

Sinikka T. Lennartz,Gisèle Krysztofiak,Gisèle Krysztofiak,Christa A. Marandino,Björn-Martin Sinnhuber,Susann Tegtmeier,Franziska Ziska,Ryan Hossaini,Kirstin Krüger,Stephen A. Montzka,Elliot Atlas,David E. Oram,Timo Keber,Harald Bönisch,Birgit Quack +14 more
TL;DR: In this paper, the authors present simulations with the chemistry climate model EMAC (ECHAM5/MESSy Atmospheric Chemistry) with online calculation of emissions based on surface water concentrations, in contrast to directly prescribed emissions.

Dimethylsulphide (DMS) emissions from the western Pacific Ocean: a potential marine source for stratospheric sulphur?
Christa A. Marandino,Susann Tegtmeier,Kirstin Krüger,Cathleen Zindler,Elliot Atlas,Fred L. Moore,Hermann W. Bange +6 more
TL;DR: In this article, the TransBrom cruise in the western Pacific Ocean between Japan and Australia in October 2009 was used as an input field for the Lagrangian dispersion model FLEXPART, which was set up with actual meteorological fields from ERA-Interim data and different chemical lifetimes of DMS.

Spatial distributions of dimethylsulfide in the South China Sea
TL;DR: In this article, the authors determined the concentration of DMS and supporting parameters in surface seawater and vertical profiles at 26 stations in the South China Sea and found that DMS concentrations were significantly correlated with seawater temperature and dissolved oxygen, but it showed an inverse relationship to nutrients (including nitrate, phosphate and silicate).

Variability of surface water fCO2 during seasonal upwelling in the equatorial Atlantic Ocean as observed by a drifting buoy
TL;DR: In this article, the fugacity of tropical Atlantic surface waters was hourly monitored by a drifting carbon interface ocean atmosphere (CARIOCA) buoy from June to September 1997 during strong seasonal equatorial upwelling.

Detecting sinks and sources of CO2 and CH4 by ferrybox-based measurements in the Baltic Sea: Three case studies
TL;DR: In this paper, the surface water CO2 partial pressure of the Finnpartner/Finnmaid vessel was measured at 2-3-day intervals between the Gulf of Finland (Helsinki) and the Mecklenburg Bight (Lubeck) in the southwest of the Baltic Sea.

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.
