Comment on Enhanced TKE Dissipation under Breaking Waves

It is noted that the results of recent experiments on the enhancement of turbulent kinetic energy (TKE) dissipation below surface waves can be stated as follows. TKE dissipation is enhanced by a factor 15Hws/z at depths 0.5Hws < z < 20Hws with respect to the wall-layer result ǫ = u ∗w/κz, where u∗w is the friction velocity in water and Hws is the significant windsea wave height. For open ocean ...

Modeling the Antenna Configuration of a Digital Very-High Frequency (VHF) Direction Finding System

The U.S. Coast Guard Academy (USCGA) has developed a prototype Digital Very High Frequency super-heterodyne Direction Finding system (DVHF-DF) in support of the U.S. Coast Guard's National Distress Response System Modernization Project (NDRSMP). This receiver, which processes four independent channels of in-phase (I) and quadrature (Q) data, offers significant advantages over more conventional ...

Very High-Frequency Radar Mapping of Surface Currents

An ocean surface current radar (OSCR) in the very high frequency (VHF) mode was deployed in South Florida Ocean Measurement Center (SFOMC) during the summer of 1999. During this period, a 29-d continuous time series of vector surface currents was acquired starting on 9 July 1999 and ending 7 August 1999. Over a 20-min sample interval, the VHF radar mapped coastal ocean currents over a 7.5 km 8 ...
