Abstract :
Microwave detection of ocean (sub)surface bubble populations including patches, patterns, flows, and wakes is considered. The physical principles are based on specific electromagnetic properties of the air-bubble-water media that produce strong anomalies in ocean thermal microwave emission, especially at X- C-, S- and L- bands (e.g., at wavelengths of 4, 6, 8, 18, and 21 cm). Related model estimations are presented.
