Repeated temperature profiles were obtained at a slowly sinking and rising free float in a depth range of 1300 to 3600 m at 10°24′N, 50°22′W during the period 15–17 October 1967. Temperature deviation...
Interaction Subrange Spectra of Turbulent Wind Over an Air-Water Interface
Interaction Subrange Spectra Air-Water Interface Turbulent Win

The nonlinear interaction of wave-induced air motion and the turbulent wind is examined in spectral space with the aid of a model developed through two averaging processes. The averaging periods are d...
Spectra of Internal Waves：In-Situ Measurements in a Multiple-Layered Structure
Internal Waves Multiple-Layered Structure In-Situ Measurements
2009/4/3
The persistence of layering between 200 and 400 m depth in the Arctic Ocean has enabled construction of accurate internal wave amplitude traces from a 30-hr series of successive temperature profiles t...
The Effect of Internal Wave Strain on Vertical Spectra of Fine-Structure
Internal Wave Strain Fine-Structure Vertical Spectra
2009/4/2
Vertical spectra of temperature perturbations are due to (i) internal wave displacement in the mean profile and (ii) fine-structure that would still be measured in the absence of internal waves. The f...
