Abstract

In order to investigate the small-scale structure of the near surface turbulence a special up-rising microstructure profiler, including a remote controlled underwater winch, was developed. The aim of these first measurements under sea conditions was to develop a deployment technology, to demonstrate the general functionality and to acquire first data sets of marine near surface turbulence in shallow water environments. During the March 1995 GOBEX expedition of the Institute for Baltic Research Warnemünde with r/v "Professor Albrecht Penck" (P.A.P.) several time series of different duration were carried out. Measurements below the ocean surface mostly tended to confirm "law of the wall" behaviour, in which the energy dissipation decays inversely with depth, but several exceptions occurred.
