    • The mixed layer is a layer at the ocean's surface that is relatively vertically uniform in properties such as temperature and salinity. The turbulence that mixes this layer is a result of wind and surface cooling.

    • The thermocline is a region of relatively high stratification below the mixed layer.

    • The Earth's rotation should act to limit the slumping at horizontal scales larger than the Rossby radius of deformation (the scale above which the effects of rotation become important). Although slumping should occur at large scales, it need not proceed until isopycnals are horizontal.

    • Sensors for measuring temperature and conductivity (which is used to calculate salinity) must be calibrated to account for differences in time constants of the sensors. We used the methods of Lueck and Picklo [R. G. Lueck and J. J. Picklo, J. Atmos. Oceanic Technol. 7, 756 (1990)] and Rudnick and Luyten [D. L. Rudnick and J. R. Luyten, J. Geophys.

    • Temperature-salinity variability below the mixed layer is caused by internal waves, stirring, and mixing. The isobar and isopycnal tows are intended to study these processes.

Fluid Mech. 24, 395 (1992). The wavelet transform may be thought of as convolutions with a set of functions (wavelets) of changing frequency content. An important feature of a wavelet is that its quality factor Q, defined as the ratio of the wavelet's central wave number to its spread in wave number, is constant. Wavelets are derived by dilation of the so-called mother wavelet Here we choose the Morlet wavelet (a plane wave modulated by a Gaussian envelope) with Q = 2√2π.
