Abstract

In the estuaries of the largest Arctic rivers, namely, the Yenisei, Lena and Mackenzie, marine worms of the family Siboglinidae have been found. Their metabolism is provided by symbiotic chemoautotrophic bacteria. The strong salinity stratification characteristic of the estuaries of the largest Arctic rivers ensures high salinity at depths of 25–36 m, where siboglinids were found. High concentrations of methane necessary for the metabolism of siboglinids arise because of dissociation of permafrost gas hydrates under the influence of river runoff in the conditions of Arctic warming
