Abstract
The modulation of short wind waves (centimeter to decimeter long) by long gravity waves is investigated under field and laboratory conditions. The field study employed a wave follower capable of tracking ocean waves with frequencies less than 1.0 Hz and heights less than 2.0 m. A high response laser-optical system was used to detect upwind-downwind and cross-wind slopes of short waves. Cross correlations of short wave slopes with long waves reveal the presence of definite coupling between the two. A well defined peak appears in the cross-correlation function at 45° downwind of the long wave crest, suggesting higher density waves there.
