An offshore measuring system for chemical biological physical parameters

In this paper we describe the conditions which led to the building of a measuring system for physical chemical and optical properties of seawater and sea-bottom. The measuring system consists of three parts. (1) The submerged sensor units. (2) The sea station placed off the coast near Boknis Eck on a tower or inside a buoy. (3) The shore station placed at our institute with the computer and the radio transceiver. The system can be used for routine measurements and or for special purposes at any time. As far as possible we use commercial sensors. In those cases where commercial sensors were not available we developed our own. Control of mechanical equipment such as samplers can be done from the shore station.
