Benthos investigations in the Lena Delta, supplement to: Gukov, Aleksander Yu (2002): Monitoring of macro-zoobenthos in the Lena River mouth. Polarforschung, 70, 107-114
According to monitoring data gained between 1982-1992, macrobenthos in the Tiksi Bay is characterized by low indices of the total abundance, biomass and taxonomic diversity. 30 macrobenthic species have been recorded in the Tiksi Bay. The bottom biocenoses within the estuarine-arctic water mass cons...

The maximal number of species was observed at a depth of 8.5 m. The maximum biomass was recorded on muddy grounds.
