Air Bubbles In An Oceanic Mixed Layer: Effect On Gas Concentrations And Air-Sea Gas Exchange, Larry P. Atkinson

CCPO Publications

This thesis attempts to determine the effect of air bubbles that are entrapped into the surface layers of the ocean by breaking waves on gas concentrations in the ocean and gas exchange across the air-sea interface. N₂ and Ar data gathered during the Hudson-70 expedition produced indications of the magnitude and nature of the effect. A mathematical model is developed that equates the input of gas via bubble solution with the vertical eddy diffusion. Published values for bubble spectra and solution rates are used and assumptions are made concerning the effect of wind on bubble spectra. The model predicts …
