From a wartime beginning focused oneffective torpedo exploders, APL-UW initiated acoustic studies andoceanographic research programs to understand how variations in the oceanenvironment affected the performance of Navy systems.Decades of acoustic and oceanographic studies yielded an understanding of theworld's deep oceans, and now APL-UW scientists are developing expertise incoastal and small-scale oceanography and the new physics required for tacticalsuperiority in shallow water environments. Our scientists and engineers makeimportant contributions to understanding the earth's climate cycles withsatellite and in situ sensing of ocean winds, currents, and air-sea fluxes;observations of Arctic sea ice, its variations and effects on mid-latitudeoceans; and ocean tomography that reveals how the abyssal ocean mixes andsequesters carbon. APL-UW continues to lead research in the basic and appliedphysics of sound?from sonars used to probe the geology of the deep ocean floorto hand-held high-frequency focused ultrasound devices to image and stopinternal bleeding without surgery.Website: http://www.apl.washington.edu/[Summary provided by the University of Washington.]
