Automated Tethered Profiler for Hydrophysical and Bio-Optical Measurements in the Black Sea Carbon Observational Site

Biogeochemical cycles of carbon transformation throughout the euphotic zone sea are controlled by physical processes, e.g., daily thermocline, variation in solar irradiance, thermohaline convection, and intermittent mixing. These processes should be regularly observed with sufficient time resolution at fixed geographical locations. This study provides a brief overview observational site Northeastern Black Sea. The focus is on design new tethered profiler Winchi for inner continental shelf part site. hull two outriggers comprise an open trimaran platform that positively buoyant tends to maintain horizontal position water. lower end winch wire secured bottom anchor. By unwinding/winding wire, ascends/descends while measuring depth profiles marine environment parameters ranging from seafloor air–sea interface. After surfacing, determines its location using Global Positioning System (GPS) transmits data (and from) server land through Mobile Communications (GSM). Initial field tests Sea exhibited promising results. We report these early demonstrate use Winchi.
