*Format: station CTD data file format of the NATO TU-BS project.
*Ship (station) name: R/V Bilim (IMS-METU, Turkey).
*Expedition: April 1993.
*Parameters: Depth, temperature, salinity.
*Instruments and methods: Seabird Electronics (SBE) CTD probe
and deck unit was used with a wire winch from the rear of the vessel.
*Accuracy: Not applicable since the instruments are not periodically
calibrated (precision is one part in ten thousand).
*Processing (if applied): Data are averaged with respect to one meter
depth bins and converted to ASCII.
*Principal investigator(s): Umit Unluata (IMS-METU, Turkey).
*Digitization: On board of the ship via deck unit under the responsibility of
the principal investigator. Processing applied at IMS-METU under responsibility
of the department of Physical Oceanography.
*Remarks: Data are reliable due to quality of the instrumentation and precise
acquisition.
*Completed by: Sinan Husrevoglu (IMS-METU, Turkey).
*Date: 25.06.1996.
*Source of data: IMS-METU.

*Data file(s): chem.dat
*Format: station data file format of the NATO TU-BS project.
*Ship (station) name: R/V Bilim (IMS-METU, Turkey).
*Expedition: April 1993.
*Parameters: Depth, hydrogen sulfide, phosphate, nitrite, silicate,
chlorophyll, DOW, nitrite+nitrate, humic matter, alkalinity.
*Instruments and methods: -Hydrogen sulfide is determined by iodometric back
titration.
-Phosphate, nitrite, silicate and nitrite+nitrate are determined by
the Technicon Autoanalyzer.
-Chlorophyll and humic matter are determined by spectrophotometric and
fluorimetric methods.
-DOW is determined by Winkler titration method.
-Alkalinity is determined by the pH-meter.
*Accuracy: Error is applicable for alkalinity and is approximately 0.05.
*Processing (if applied): None.
*Principal investigator(s): Ozden Basturk (IMS-METU, Turkey).
*Digitization: Single-key entry at IMS-METU under supervision of Ozden
Basturk (IMS-METU).
*Remarks: Data are reliable in the sense of qualified staff and
instrumentation, however no error bounds or intercalibrations are present.
*Completed by: Sinan Husrevoglu (IMS-METU, Turkey).
*Date: 25.06.1996.
*Source of data: IMS-METU.

*Data file(s): sd.dat
*Format: station data file format of the NATO TU-BS project.
*Ship (station) name: R/V Bilim (IMS-METU, Turkey).
*Expedition: April 1993.
*Parameters: Secchi disk depth.
*Instruments and methods: Standard Secchi disk (0.3 m in diameter) fixed on
the rosette where the Nansen bottles, the CTD probe and the additional
sensors are. The disk is fixed at a known height offset from the pressure
sensor.
*Accuracy: Approximately 0.5 m.
*Processing (if applied): Corrections are made for the wire angle.
*Principal investigator(s): Aysen Yilmaz (IMS-METU, Turkey).
*Digitization: Single-key entry at IMS-METU.
*Remarks: The depth is determined by the pressure sensor of the CTD probe
and the staff are reliably experienced.
*Completed by: Sinan Husrevoglu (IMS-METU, Turkey).
*Date: 25.06.1996.
*Source of data: IMS-METU.
