Linking biogeochemical signatures to archaeal community structure at active methane seeps in the Tatar trough, far eastern Russia

•Distinct methane migration pathways were identified between two active seep sites in the Tatar Trough.

•Multi-proxy analyses revealed intensified anaerobic oxidation of methane near shallow SMTZs.

•Strongly 13C-depleted archaeal lipids indicated active methane-derived carbon assimilation.

•ANME-1 and Seep-SRB1 communities were closely associated with active seep environments.

•Results provide new insight into methane cycling linked to gas hydrate destabilization.
