The thinness of oceanic temperature gradients

Creator:

Caldwell, Douglas R., Chriss, T. M., Newberger, P. A., and Dillon, T. M.

Abstract:

A test of the scaling of the extent of the thinnest vertical temperature gradients, in the near-bottom boundary layer on the Oregon shelf, shows that the Batchelor wave number determines the cutoff wave number in vertical temperature gradient spectra. In combination with previous results, in other words, this test shows...

The scaling of vertical temperature gradient spectra

Creator:

Caldwell, Douglas R., Dillon, T. M., Brubaker, J. M., Newberger, P. A., and Paulson, C. A.

Abstract:

Tests of a formula derived for the cutoff wave number of vertical temperature gradient spectra, using data taken in the upper layers of the North Pacific, show encouraging results. To derive this formula, the cutoff wave number is assumed to be the Batchelor wave number, with kinetic energy dissipation calculated...

An inertial subrange in microstructure spectra

Creator:

Newberger, P. A. and Caldwell, Douglas R.

Abstract:

An inertial subrange was found in spectra calculated from vertical profiles of temperature gradient recorded in the bottom boundary layer of the Oregon shelf. Spectra were calculated for 53-cm vertical segments. An ensemble average of those spectra that were fully resolved and had high Cox number was compared to the...
