contenttypeSummary

The CTD probe measures conductivity and temperature along a vertical transect through the water body. The measured parameter are used to calculate the salinity of the water. Additionally, up to 24 water samples can be taken in different water depths during the CTD measurements. A fluorometer, an oxygen sensor and a transmissiometer are attached to the CTD as well. The system is operational up to 2000m water depth.

Components

The CTD system consists of the underwater unit SBE 9plus, the deck unit SBE 11plus V2 and the carousel water sampler SBE32 which is equipped with free flow water samplers manufactured by Hydro-Bios. The CTD is outfitted with a double set of temperature (SBE 3plus) and conductivity (SBE 4C) sensors that are calibrated regularly. Additionally, an altimeter, a transmissometer, an oxygen sensor and a fluorometer may be attached to the CTD unit and operated to water depths of 6000m.

On the CTD data aquisition PC in the Messraum following software is installed: aquisition software Seasave (Version V7_19), SBE Data processing software, ManageCTD software packet for cleansing and conversion of the data and Ocean Data View (ODV) for visualization.

Under the table in the Messraum a frame with four backup bottles is installed.

Central geographical ship's position and time standard

The PC is time synchronised via the Windows-Domain-Affiliation. Geographic position and UTC time is made available to the system via NMEA telegram and read by Seasave software.
