*Data file(s): ML13zoo.csv, ML13jud.csv

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

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

*Expedition: cruise number 13, March 1963.

*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 0.125 mm. 
The open-closing mechanism used was the Nansen mechanical lock system 
allowing nets to be vertically towed through standard depths 
(0-10, 10-25, 25-50, 50-100, 100-200, 200-300, 300-500m) and closed 
at the upper depth level.
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.
