Variations and gradients between methane seep and off-seep microbial communities in a submarine canyon system in the Northeast Pacific.

ABSTRACT: Methane seeps are highly abundant marine habitats that contribute sources of chemosynthetic primary production to marine ecosystems. Seeps also factor into the global budget of methane, a potent greenhouse gas. Because of these factors, methane seeps influence not only local ocean ecology, but also biogeochemical cycles on a greater scale. Methane seeps host specialized microbial communities that vary significantly based on geography, seep gross morphology, biogeochemistry, and a diversity of other ecological factors including cross-domain species interactions. In this study, we collected sediment cores from six seep and non-seep locations from Grays and Quinault Canyons (46-47°N) off Washington State, USA, as well as one non-seep site off the coast of Oregon, USA (45°N) to quantify the sc
