Attention:
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 to AWI-Logistics prior to the cruise and clarify the data transfer after the cruise.

Components
The CTD underwater unit is equipped with 2 temperature (SBE3plus) and 2 conductivity (SBE4C) sensors by default, which are calibrated on a regular basis. Several external sensors are available, which can be used in water depth up to 6000m: altimeter (Benthos PSA-916D), Fluorometer (Dr. Haardt or Wetlabs EcoFLR), Oxygen sensor (SBE43), Transmissiometer (Weblabs CStar 25cm), mechanical bottom detector.
