A towed CTD chain for two-dimensional high resolution hydrography
TL;DR: In this paper, the authors describe the development of a new type of towed chain, where low-cost sensors are moulded in fins and may be randomly placed on the tow cable, to which they are inductively coupled for power supply and communication with a deck unit.
Journal ArticleDOI
Horizontal wave number distribution of potential energy in the ocean
TL;DR: In this article, the horizontal spectra of temperature fluctuations on wavelengths from the mesoscale to the fine scale were combined with intermediate-scale isopycnal displacement data of Katz (1973), and a composite potential energy spectrum was constructed which spans scales from 2 cm to 2000 km, a range of eight decades in wave number.
MonographDOI
Observations of turbulence, internal waves and background flows : an inquiry into the relationships between scales of motion
TL;DR: In this paper, the authors examined the parameterization of turbulent dissipation due to internal waves in the ocean profile data and found that strong stratification, low average wave frequency and Coriolis frequency are the limiting factors for dissipating turbulent fluxes.
Journal ArticleDOI
Statistics of small-scale activity in the upper ocean
TL;DR: In this article, a measure of the activity level is computed as the variance of horizontal gradients of temperature or conductivity normalized by the square of the mean vertical gradient, essentially a pseudo Cox number, in eight wavelength bands across this range of scales.

CTD time-constant correction
A.S. Bennett,Teng Huaide +1 more
TL;DR: In this article, a method of correcting CTD data for dynamic errors resulting from time-constant mismatch has been developed which uses only the observed data and does not require separate measurements of sensor responses.

Turbulence spectra from a tidal channel
TL;DR: In this article, the authors used a hot film flowmeter in the sea and presented experimental measurements of the downstream component of turbulent velocity in a tidal channel, where the Reynolds number of the flow is about 108 and the scale of the turbulence is so large that a ship is carried about to a considerable extent by the energy-containing eddies.
Journal ArticleDOI
The oceanic microcosm of particles.
TL;DR: Analysis of suspended particulate matter larger than 1 micrometer, filtered from thousands of liters of surface and deep waters during GEOSECS expeditions to the Atlantic and Pacific oceans, have provided new information on the nature and time scales of chemical processes associated with the particles.
Journal ArticleDOI
Distribution and particle size of suspended matter in the Southern Bight of the North sea and the Eastern channel
TL;DR: The size distributions reflect the multiple origin of the suspended material and the variable conditions of deposition, resuspension and aggregation.
Journal ArticleDOI
Microstructure and fine structure in an upper ocean frontal regime
TL;DR: In this article, a simple temperature/salinity (T/S) technique was used to examine the occurrence of temperature microstructure and T/S fine structure in relation to a mesoscale feature which may be part of a frontal region between coastal and oceanic waters in the northeastern Pacific.
Journal ArticleDOI
A data processing method for salinity, temperature, depth profiles
TL;DR: In this paper, a reduction procedure for data from salinity, temperature, depth (STD) and conductivity (CTD) oceanic profilers is described, which is used on data from eight profilers and three different logging systems in the MODE-I experiment.
