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.
Summary
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.
