*Data file(s): ML47DATA.csv, ML47-newcast.csv

*Format: phytoplankton sample file format (see file format_description.txt on the INTAS - 00-059 CD).

*Ship (station) name:  R/V Mikhail Lomonosov (MHI, Ukraine).

*Expedition: cruise number 47, July, 16 1986 - September, 16 1986.

*Parameters: SampleID - up to 10-character unique sample identifier; 
   Genera+Species - taxonomic name of species; 
   Cells/l - abundance or concentration (number per liter) in liter; 
   Mg/m3 - biomass or concentration (wet weight per cubic meter) in mg/m-3; 
   
*Instruments and  methods:  Phytoplankton samples were taken by sampling bottles from different depths of 0 - 100 m layer. Samples were concentrated by the method of back filtration. Nucleopore filters D = 1.5 mkm were used. Samples were fixed by Lugol's solution and after sample blooming - by 40% formaldehyde. After expedition samples were concentrated by siphon down to 2-10 ml volume. Calculations of phytoplankton cells numbers were made in 0.05 ml drop using light microscope and then recalculated for 1 liter. Additionally, sediments of samples were examined in Bogorov's chambers to reveal large and rare cells. 

*Accuracy: The error of the depth determination is approximately 0.5 m.

*Processing (if applied): Biomasses of phytoplankton algae were calculated considering cells' volumes by equating real or average volumes of cells to corresponding geometric figures by Senichkina (1976, 1986)(see file references.txt on the INTAS - 00-059 CD).
