Abstract

Eighty-one CTD profiles gathered in springtime were used for northern East China Sea thermohaline finestructure studies indicating that the finestructure properties varied with region and depth, as shown in finestructure spectra, distribution of Cox numbers, etc., Some results closely related to distribution of water masses and currents. Analysis of two typical profiles revealed differences in autospectra of temperature, salinity and potential density gradients, probability distribution of temperature finestructure gradient, Cox numbers, etc. The probability density function of vertical temperature gradients, which varied with sample interval, is given. The variances of temperature finestructure gradient are used to estimate the lateral diffusivity {ie128-1} and lateral temperature flux, which were 10.3 (m2/s) and 5.5×10−4 (°C m/s). respectively.
