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.

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.
Rawdata storage on board
...
...
Raw data are stored with the ManageCTD software on the aquisiton PC in following data structure:
| root directory | \\xdc\scientists\data\CTD\ |
| directory name | CruiseNo e.g. HE507 with subdirectories |
| data volume (MB per day) ca. | 50 |
| number of files per day ca. | 10 |
