A specific objective is to test the Phillips [1985] hypothesis relating the distribution of breaking crests (as recorded remotely using imagery) with the energy dissipation of breaking crests (as recorded in the water using acoustic velocity profilers). Another specific objective is to evaluate the use of infrared imagery in detecting and quantifying microbreakers (waves that break but do not form a whitecap) in the field. Visual (top) and infrared (bottom) images of a breaking wave. Field data were successfully collected from the R/V Henderson on Lake Washington (November 2006) and Puget Sound (February 2008). Conditions include winds up to 20 m/s and significant wave heights up to 60 cm. Data analysis is ongoing. R/V Henderson on Lake Washington, with 10-m imaging tower and 7-m instrument boom. Location of measurements and relevant fetch on Lake Washington. R/V Henderson moored at Pt. Wells. LakeEx and SoundEx research locations.
