The role of bubbles during air-sea gas exchange

The potential for using the air-sea exchange rate of oxygen as a tracer for net community biological production in the ocean is greatly enhanced by recent accuracy improvements for in situ measurements of oxygen on unmanned platforms. A limiting factor for determining the exchange process is evaluating the air-sea flux contributed by bubble processes produced by breaking waves, particularly dur...

Dissolution without disappearing: multicomponent gas exchange for CO2 bubbles in a microfluidic channel.

We studied the dissolution dynamics of CO2 gas bubbles in a microfluidic channel, both experimentally and theoretically. In the experiments, spherical CO2 bubbles in a flow of a solution of sodium dodecyl sulfate (SDS) first shrink rapidly before attaining an equilibrium size. In the rapid dissolution regime, the time to obtain a new equilibrium is 30 ms regardless of SDS concentration, and the...

Composition of Gas Bubbles in Greenland Icebergs-

An investigation has been made on the amounts and composition of gases enclmed in West Greenland glaciers ranging from the Thule area near lat. 77° N. to Brede l:<Jordat lat. 62° N. In general, the gas composition deviated appreciably from that of air, and also varied within each piece of ice. Presumably these variations are caused by melting either in the firn area, or, more often, at the outl...
