Ship (station) name: R/V "Professor Vodyanitsky" (IBSS, Sevastopol)
Expedition: cruise number 11, January, 1982.
Parameters: depth,  temperature (T),  salinity (Sal),
            chlorophyll"a"(chl"a"), phaeopigments (Ph,%), phosphate
            (PO4),  nitrate  (NO3), oxygen (O2), Bioluminensence
Instruments and methods:  Depth,  temperature,  salinity were measured
with a  bathysonde  "Istok". 
Samples  for PO4,  NO3 and O2 were collected from
the most sampled depths.  The concentrations of PO4,  NO3 and O2  were
determined by  the  methods  of  Grasshoff (1976).  For measurement of
chlorophyll"a" and phaeopigments 3-5  l  water were  filtered  through
0,6 mkm  membrane filters.  Determination of chlorophyll"a" and phaeo-
pigments were carried out soon after sampling on board. Chlorophyll"a"
and  phaeopigments  concentrations  were  determined  fluorimetrically
(Yentsch and Menzel,1965;  Lorenzen,1967). The analysis of these para-
meters  were  carried by use laboratory fluorimeter constracted on the
base of spectrophotometer "Specol" fitted with a red sensitive  photo-
multiplication,  blue lamp, blue filter and red filter. Calibration of
fluorimeter was made with pure chlorophyll"a" in 90%  acetone with its
concentration first measured on a spectrophotometers.
Accuracy: The error of: depth -  +-1 dbar;
                        temperature -  +-0,01 grad C
                        salinity -  +-0,03 %o
                        P-PO4 -  +-0,05 mkM
                        N-NO3 -  +-2%
                        O2  -  +-1 mkM
                        chlorophyll"a" - +-0,01 mg/m^3
                        phaeopigments -  +-10%
