Ay. Gukov et al., Peculiarities of distribution of macrobenthos biomass of the upper sublitoral in south-eastern part of the Laptev sea, OKEANOLOGIY, 39(3), 1999, pp. 406-411
The macrobenthos biomass of bottoms biocenosis in the sublittoral of the La
ptev sea were studied. The macrobenthos is characterize by the low indices
of total density (from 680 to 3440 ex/sq.m), biomass (from 28,2 to 70,42 g/
sq.m) and species diversity total registered number of species is 62). The
major features of the spatial distribution of the macrobenthos biomass are
closely related to sediment characteristics and salinity. The biomass of ma
crobenthos in the surface arctic water mass is considerably higher than in
the estuary arctic one and have a distinct tendency towards decline at dept
hs of contact of water masses. The highest biomasses of the biocenosis are
observed in the cores of the water masses.
