Abstract:
Measurements using side-scan sonar have been made in a fresh-water lake, Loch Ness. A 250-kHz side-scan sonar has been used to detect breaking waves and to measure the proportion of waves that are breaking and producing bubble clouds as a function of wind speed. General agreement is found with earlier estimates using in-situ probes [Longuet-Higgins and Smith, J. Geophys. Res. 88, 9823–9831 (1983); Weissman, Atakturk, and Katsaros, J. Phys. Oceanogr. 14, 1608–1619 (1984)]. Bands of bubble clouds indicating areas of local convergence are observed using 80- and 90-kHz sonar. The observed convergence speeds and persistence times of the bands are used to derive estimates of lateral, cross-wind, dispersion rates of floating particles as a function of environmental conditions.
