ABSTRACT
Three neutrally buoyant floats were air deployed ahead of Hurricane Dennis on 28 August 1999. These floats were designed to accurately follow three-dimensional water trajectories and measure pressure (i.e., their own depth) and temperature. The hurricane eye passed between two of the floats; both measured the properties of the ocean boundary layer beneath sustained 30 m s^sup -1^ winds. The floats repeatedly moved through a mixed layer 30-70 m deep at average vertical speeds of 0.03-0.06 m s^sup -1^. The speed was roughly proportional to the friction velocity. Mixed layer temperature cooled about 2.8[degrees] and ...
