Abstract
Microbubbles from 2 m below the wave trough to the largest depth of 21 m, and within the diameter ranges of 20 to 400 µm were measured near the NORDSEE platform in the North Sea by means of an optical device based on the dark-field specular reflection. The most striking results are (1) a close similarity in shape of bubble concentrations under a wide range of wind/wave conditions and over the depth range of the measurements, and (2) a distinctive concentration maximum appearing between the bubble diameter of 40 to 50 µm, (3) a power law dependence of bubble density on wind speed, and (4) a lack of a clear depth dependence in the bubble concentrations.
