Ship (station) name: R/V "M.Lomonosov" (MHI, Sevastopol)
Expedition: cruise number 40, September, 1980.
Parameters: depth,  temperature (T), phosphate (PO4),
            particulate organic carbon (POC), particulate organic
            nitrogen (PON), chlorophyll"a" (chl"a"), 
            attennuation coefficient (E),
Instruments and methods:  Depth,  temperature,  salinity were measured
with  a  bathysonde "Istok".  
Samples for PO4 were collected from the most sampled  depths. 
Samples for POC & PON were filtered onto precombusted 25 mm Whatman
GF/C filters.
Filters for POC and PON were analysed by combustion in a CHN-analyzer.
For  measurement  of  chlorophyll"a" 3-5 l water was filtered
through Whatman GF/C glass fiber filters. Determination of chlorophyll
was  carried  out soon after sampling on board.  The analysis followed
the spectrophotometric method (UNESCO,  1966). Diffuse attenuation co-
efficient was measured with a submersible quantum sensor of the spect-
rum at 480 nm.  The sensor has a cosine collector, a colour filter and
a selenium element.
 Accuracy: The error of: depth -  +-1 dbar;
                        temperature -  +-0,01 grad C
                        salinity -  +-0,03 %o
                        P-PO4 -  +-0,05 mkM
                        POC -  +-5%
                        PON -  +-5%
                        chlorophyll"a" - +-0,01 mg/m^3
                        Attenuation coefficient - +-0,01 m^-1
