High Resolution Doppler profiler measurements of turbulence from a profiling body

Abstract

A Nortek Aquadopp High Resolution (HR) Profiler was mounted on a moored vertical crawling oceanic profiler to determine if measurements made from a moving platform could be utilized to measure turbulence. Initial results are promising for this application but have highlighted potential challenges which must be addressed in the post-processing stage, in particular removal of the profiler motion from the measured velocities. Despite the potential complexity of this process, measurements from a moving body yield correct order of magnitude estimates of turbulence intensity at a study site in the Puget Sound region.
