A thermograd record obtained over the Ayes Ridge indicated existence, at the time of observation, of a cold layer of water in the lowest 13 meters, undergoing high-frequency internal oscillations. The great discontinuity in temperature across the sedimnent-water interface and the lack of agreement with the normal temperature structure indicate that the layer was a transient feature. This abnormal condition may be related to the passage of a hurricane 3 days earlier.
