*Data file(s): PV18zoo.csv, PV18Jud.csv

*Format: zooplankton sample file format of the DARWIN INITIATIVE PROJECT.

*Ship (station) name:  R/V Professor Vodyanitsky (IBSS, Ukraine).

*Expedition: cruise number 18, December 1984 - March 1985.

*Parameters: SampleID - up to 10-character unique sample identifier; 
   Species - taxanomic name of species; Stage - life history or sex; 
   Count - number of specimens in sample; 
   N/m3 - abundance or concentration (number per cubic meter) in m-3; 
   B/m3 - biomass or concentration (wet weight per cubic meter) in mg/m-3; 
   AvSize - average length in mm; 
   AvWeight - average wet weight of organizms in mg. 

*Instruments and  methods:  Mesozooplankton was sampled by open-closing 
JUDAY net with a 36 cm ring diameter and mesh size of 125 mkm. 
The open-closing mechanism used was the Nansen mechanical lock system 
allowing nets to be vertically towed through depths with the temperature gradient maximum
( from 10-40 down to 50-100 m) and closed  at the upper depth level. 
Integrated hauls (0-100 m) were also taken. 
Depth of tow was evaluated by wire paid out and the angle of wire  inclination. 
The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and 
processed on return to the laboratory. All of copepods were identified 
to genus level, other taxanomic groups - to type, class, order and family 
levels. Individual weight of organisms was calculated from measurements of 
body length using the so-called Tables of Standard Weights (Kanaeva, 1962; 
Shmeleva, 1963; Kryilov, 1968; Gruzov, Alexeeva, 1970) or nomograms relating 
the length and a typical body shape with the weight of animals (Chislenko 1968).

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