*Ship name: Palamida or Steaua de Mare (RMRI, Constantza, Romania).
*Expedition: Two cruises each year (May and August 1990,
May and September 1993), 3 transects with 8-10 stations
in front of Danube Delta (Sulina, Sf.Gheorghe, Portita).
*Parameters:Zoobenthos total biomass (g/m2).
*Instruments and methods: Sampling on depths on bathymetric zones:
10-20m, 20-30m, 30-40m, 40-50m with Van Veen grab (1/20m2); samples
treated on board with 4% formaldehyde. In laboratory, each sample
was sieved by 1mm, 0.25mm and 0.10mm mesh screen; animals were
removed under a microscope, identified to species and counted.
The biomasses of the organisms smaller than 2mm were calculated
using tables of weights and of those than 2mm by weighting.
