CTD Probe with Carousel Water Sampler

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 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.

Data logging, storage and archiving

Logged parameters

No parameters available.

Central geographical ship's position and time standard

Time synchronising of the computers is regulated via Windows Domain affiliation. UTC time is supplied via NMEA telegram and processed by Seasave software.
Geographical position is supplied via NMEA telegram and processed by Seasave software.

Rawdata storage on board

Mass data: The ManageCTD software produces data files in the mass storage.

root directory	\\polsrv1\data01\CTD
directory name	CruiseNo e.g. ANT-XXVI-1
file name	several files in the following subdirectories: btl conf1 dsp final mat odv work
Data volume (MB per day) ca	50
Number of files per day ca	10

Data archiving on land

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).

File format(s)	raw data: .hex, .bl, .hdr, .xmlcon; processed data: *.txt
Calibration certificates	YES
Location of certificates	PI (calibration data is stored in *.xmlcon file)
