Abstract
Temperature and velocity fluctuations have been recorded in the open sea and in a tidal channel, and power spectra have been determined from the records. The one-dimensional spectra of temperature fluctuations are found to have an inertial subrange. Atlarger wave-numbers the data can be fitted by Batchelor's spectrum function for the viscous-convective range. Estimates are given for the constants in Batchelor's spectrum function. There is doubt about the validity of some of the velocity spectra, and in other cases there is reason to suspect that the turbulence is not locally isotropic.
