Description:
*Data file(s): 67601.dat...67606.dat, 67700.dat...67702.dat,
67800.dat...67802.dat.
*Format: station CTD data file format of the NATO TU-BS project.
*Ship (station) name: R/V Bilim (IMS-METU, Turkey).
*Expedition: December 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: December 1993.
*Parameters: Depth, hydrogen sulfide, phosphate, nitrite, silicate,
DOW, nitrite+nitrate.
*Instruments and methods: -Hydrogen sulfide is determined by iodometric back
titration.
-Phosphate, nitrite, silicate and nitrite+nitrate are determined by
the Technicon Autoanalyzer.
-DOW is determined by Winkler titration method.
*Accuracy:
*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.
