Notes
Tintinnids were identified in 256 samples from 60 stations in the North Sea investigated by a German multidisciplinary [Zirkulation und Schadstoffumsatz in der Nordsee (ZISCH)] program, during late spring of 1986. The distribution of the most frequently occurring species, Parafavella elegans, P. denticulata, Acantrhostomella norvegica, Helicostomella subulata, Ptychocylis urnula, Stenosemella nivalis, Tintinnopsis beroidea and T. parvula, was described. Some species showed a similar horizontal distribution. However, a vertical division was evidenced after analyzing species abundances against temperature, salinity, depth and sigma-t. Cellar carbon content for each species and the total weight of carbon per sample were estimated. The total weight of carbon in tintinnids in the North Sea was calculated to be 113,608 tons, with a depth-integrated average 197.58 mgC m-2, the bulk of this biomass (44%) was concentrated in the euphotic zone (0-20 m).
