Abstract: This paper describes observations of large-amplitude, long internal waves in Babine Lake. A unique feature of the observations is that they were taken simultaneously at several different points along the major axis. This ...

Abstract: Air bubbles can be used as oceanographic tracers that indicate the strength of a downwelling current by which they are subducted. In a tidal front in the Fraser Estuary, British Columbia, Canada, vertical currents of up ...

Abstract: The cooling of a freshwater take provides an opportunity for studying wind mixing and restratification under the peculiar conditions associated with a density maximum. The concepts are explored using a mixing-layer model ...

Abstract: An acoustical system is described with emphasis on its signal-processing scheme. The system consists of a small broadband hydrophone array of span 8.5 m and 5-kHz bandwidth, which is able to track individual breaking surface ...

Abstract: A multifrequency acoustical-backscatter technique is described for determining the size distribution of bubbles with radii between 8 and 130 µm. The method makes use of the resonance in the microbubbles and operates at six ...

Abstract: An acoustical instrument has been developed to measure path-averaged horizontal current and vorticity in the subice boundary layer of the eastern Arctic during the spring of 1989. A triangular acoustic array of side 200 m ...

Abstract: ime series observations of nonlinear internal waves in the deep basin of the South China Sea are used to evaluate mechanisms for their generation and evolution. Internal tides are generated by tidal currents over ridges ...

Abstract: A large eddy simulation (LES) model is used to investigate an upper-ocean response to a fall storm in the open ocean of the North Pacific Ocean. The storm is characterized by rapid increases in wind speed and surface heat ...

Abstract: Measurements of temperature fluctuations and air entrainment within the upper 1 m of the surface caused by breaking surface waves have been acquired with a novel surface-following sensor array. Brief temperature fluctuations ...

Abstract: Pinkel and Smith have recently suggested the use of repeat-sequence coded pulses to increase the time-bandwidth product for single-ping incoherent Doppler velocity measurements with sidescan sonars. Comparisons between ...
