temperature, and (c) salinity. The lower part shows (d) the corresponding contour plots of VB t B
versus depth and (e) S versus VB t B . The dashed line (S) in the contour plot VB t B -T corresponds to
the air-sea interface as indicated by the conductivity sensor using criteria C = 4.6 S/m, where
C is the water conductivity. Wind speed is 3.3 m sP
