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

Modelling atmosphere—ocean CO2 transfer
TL;DR: Current knowledge of the gas exchange coefficient is summarized, including recent new evidence which supports lower gas exchange rates and which, therefore, generally supports the Liss-Merlivat prediction for less soluble gases.

Atmospheric Deposition of Chemical Contaminants to the Great Lakes
TL;DR: In this paper, the atmospheric transport and deposition of chemical contaminants is a dominant source for many of these chemicals, but accurate estimates of the fluxes have been elusive, and data for the concentrations of trace substances in various environmental compartments are scant, and several important transfer processes are not fully understood.

Lake Metabolism: Comparison of Lake Metabolic Rates Estimated from a Diel CO2- and the Common Diel O2-Technique.
TL;DR: The data suggest that it can be advantageous to estimate respiration rates assuming negligible gradients in vertical fluxes rather than including gas exchange with the atmosphere but neglecting vertical mixing in the water column, suggesting that O2 and CO2 emissions from lakes can be decoupled from the metabolism in the near surface layer.

CO2 discharge from the bottom of volcanic Lake Rotomahana, New Zealand
Agnes Mazot,Florian M. Schwandner,Bruce Christenson,Cornel E. J. de Ronde,Salvatore Inguaggiato,Brad Scott,Duncan Graham,K. Britten,J. Keeman,Karine Tan +9 more
TL;DR: In this article, the authors performed CO2 flux surveys on Lake Rotomahana, New Zealand and found that the main source of CO2 to the atmosphere is by diffusion covering 94.5% of the lake area and to a lesser extent, bubbling.

Fco2 Variability at the Cariaco Tropical Coastal Upwelling Time Series Station
TL;DR: The CARIACO (CArbon Retention In A Colored Ocean) oceanographic time series was used to study temporal variability in Total CO2 (TCO2) concentrations and CO2 fugacity (fCO2) at this tropical coastal wind-driven upwelling site as discussed by the authors.

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.
