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.

The system consits of the CTD underwater unit (SBE9), the CTD shipboard equipment (SBE11), the watersampler carousel (SBE32) with 24 x 12 liter bottles (OTE) and the data acquisition computer with installed data acquisition software Seasave (V7.23.1) and data processing software SBE Data Processing (V7.22.5) and ManageCTD.
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.

After the cruise, the operator transfers the measurement data along with required meta data to AWI after consultaion with the data scientist and AWI Logistics. Then, the data (including meta data) can be made available on https://www.pangaea.de/ (for authorized users only).
