Observations of temperature between 20 and 40 m depth were made with a towed thermistor chain in the North Pacific (50N, 145 W) during the Mixed Layer Experiment (MILE). The chain was usually towed at a speed of 3 m/s around a 20km square on alternate days for a three-week...
This is the first data report of a program designed to study physical
processes in Oregon shelf waters by means of moored instrument arrays.
Various statistics and plots of smoothed data are presented for time
series of current velocity and of temperature. Data were collected in
July, August, September, and...
A 3°N to 3°S transect of the equator at 140°15'W was made in November 1984. Vertical profiles of temperature, conductivity and turbulent dissipation were obtained at approximately 1 km intervals. Contrary to previous results, we found no obvious peak in dissipation either at the equator or clearly associated with the...
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...
Appearing in this issue of the Journal of Physical Oceanography are three papers that present new observations of a distinct, narrow band, and diurnally varying signal in temperature records obtained in the low Richardson number shear flow above the core of the equatorial undercurrent. Moored data suggest that the intrinsic...
Temperature was observed in the upper 80 m by moored thermistor chains at three locations in Rockall Channel west of Scotland. Isotherms were interpolated, and a 1‐week period of exceptionally energetic tidal oscillations was analyzed. The moored array (horizontal separations ranging from 6 to 20 km) was used as an...
High correlations between turbulent dissipation rates and high-wavenumber internal waves and the high values of turbulent dissipation associated with internal wave activity suggest that internal waves are the main direct source of mixing in the thermocline above the core of the Equatorial Undercurrent. An extensive dataset obtained using a microstructure...
In the low Richardson number shear flow above the Pacific Equatorial Undercurrent, a single vertical microstructure profile intersected the overturning crest of a packet of high horizontal wavenumber waves. The observed dissipation rates within the overturning wave were so high that if they were representative of the volume-averaged rate, the...
Moored temperature observations were obtained at an array of buoys in the North Atlantic (59° 00.2'-59°10.7'N, 12°27.4'-12°33.6'W) during the Joint Air-Sea Interaction Experiment (JASIN) of 1978. Observations were taken at 10-minute intervals by use of thermistors at 21 depths ranging from 4.5 m to 81.5 m. Plots of temperature as...
