Abstract
The principal research effort has been towards an understanding the high-frequency tail of the surface gravity wave spectrum, lengths of 2 cm to 60 cm. These are principally responsible for wind drag on water. The analysis was based on a unique data set from geophones and hydrophones at 5 1/2 km depth midway between California and Hawaii. The measured spectral intensity around 10 Hz gives a more accurate measure of local winds than the standard satellite scatterometry. A spectral gap at the 30 Hz gravity to capillary transition offers new opportunities for spectral monitoring. We are making progress towards understanding the generation processes. A continuing effort towards the acoustic monitoring of ocean processes has been directed at the polar ocean cavities sandwiched between the floating ice sheet and the sea floor. We are exploring a possible tomography experiment in the Ross Sea with the goal of better predicting polar ice melting processes and the associated global rise in sea level.
