*Format: station CTD data file format of the NATO TU-BS project.
*Ship (station) name: R/V Bilim (IMS-METU, Turkey).
*Expedition: August 1988.
*Parameters: Depth, temperature, salinity, dissolved oxygen.
*Instruments and methods: Seabird Electronics (SBE) CTD probe with additonal
oxygen sensor 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, chem1.dat
*Format: station data file format of the NATO TU-BS project.
*Ship (station) name: R/V Bilim (IMS-METU, Turkey).
*Expedition: August 1988.
*Parameters: Depth, temperature, salinity, hydrogen sulfide, phosphate,
nitrite, silicate, chlorophyll, humic matter, DOP, nitrite+nitrate, TOC.
*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.
-DOP is obtained through the sensor on the CTD probe.
-TOC is determined by the Technicon WET Method (persulfate digestion
under a UV source).
-Temperature and salinity are determined by the CTD probe.
*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.

*Instruments and methods: Known volume (i.e. 1-2 liter) of water is
filtered through GF/C filter papers and dried for weighing for the
determination of TSS.
