Abstract

Representatives of pogonophores (Annelida, Siboglinidae), whose vital activity is provided by symbiotic chemoautotrophic bacteria that oxidize methane and hydrogen sulfide, were found in the St. Anna trough at depths of 539 m and 437 m. The discovery of pogonophores indicates high concentrations of methane, which can occur because of dissociation of bottom gas hydrates under the influence of the influx of warm Atlantic water penetrating into the Kara Sea along the St. Anna trough.
