Romania), Emil Racovita, Gr. Antipa (Military Navy, Constantza).
*Expedition: Periodically (three-five times on year) cruises,
1 transect with 5 stations, east of Constantza.
*Parameters:Zoobenthos total biomasses (g/m2).
*Instruments and methods: Sampling on depths on bathymetric zones:10-20m,
20-30 m, 30-40m, 40-50m with Van Veen grab (1/20m2);samples treated on board
with formaldehyde 4%. In laboratory each sample was sieved by 1mm,
0.25mm and 0.10mm mesh screen; animals were removed under a microscope
identified species and counted. The biomasses of the orgamisms smaller
than 2 mm were calculated using tables of weights and of those larger
2mm by weighting.
