Doppler sonar observations from the Arctic Internal Waves Experiment and Arctic Leads Experiment in the Beaufort Sea are used to examine currents below the ice during spring conditions. Following two strong wind events, the dominant fine-scale current consists of both downward and upward propagating near-inertial internal waves. The downward propagating waves are most evident above 100 m depth, while the upward waves are most energetic below this depth. The appearance of these waves coincides in time and depth with a westward subinertial current following the winds with maximum speeds of 0.05 m s-1 at 100 m depth. Simple ray simulations show that the observed subinertial shear can significantly refract near-inertial waves with length scales similar to those observed. In particular, waves that propagate both in the direction of the current and toward the depth of maximum current are enhanced. These simulations suggest that the observed near-inertial wave enhancement is due, in part, to wave-shear effects rather than solely to surface forcing. ¿ American Geophysical Union 1996 |
