Abstract:
Backscatter and forward-scatter measurements were made at frequencies ranging from 20 to 50 kHz (principally 21 and 40 kHz) in Lake Washington. Simultaneous measurements were made of the wind speed, stress, and direction, and of the large and small scale wave height up to frequencies of 30 Hz. The wave height sensors penetrated the water surface at the approximate center of the area of ensonification, allowing a spatially as well as temporally simultaneous comparison of scattering levels with wave height. Preliminary results show the backscatter level to be about 10 dB less than in the open ocean for a given wind speed. This result may be due to differences in near-surface bubble size density distributions between salt and fresh water [Scott, Deep-Sea Res. 22, 653–657 (1975)].
