Continued Development of the Autom?ted Tethered Profiler Winchi

This article describes a new tethered profiler Winchi designed as a compact, easily deployed device for measurements of aquatic parameters from 60 m depth to air-water boundary. The profiler is capable of working from subsurface buoy or bottom anchor. It can obtain the long time series of the depth profiles of aquatic parameters during 6 months if measured once per day. Preliminary results of the profiler’s evaluation are also presented.
