Distribution of meroplankton in the southern Kara Sea in relation to local hydrographic pattern
Meroplankton was investigated at 11 Stations in the southern Kara Sea and the Yenisei Estuary in August 2000. Larvae of 31 benthic taxa representing 10 higher groups were identified. Meroplankton was present almost at all stations and depth levels. The two most abundant groups were Echinodermata (68...
