Please note that operations of the CTD (Conductivity-Temperature-Depth) watersampler requires experienced scientific staff on board. The system is not operated by the ship's crew. Announce operations with the CTD Watersampler watersampler to AWI-Logistics prior to the cruise and clarify the data transfer after the cruise. |

|---|
|
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.
