    Science objectives/activities planned:
Objectives:
Study the ecology, physiology and evolution of methane seep sediment faunas (with focus on dorvilleid polychaetes) in association with microbial and geochemical environments. Specific tasks will include
(1) deployment and recovery of colonization tray experiments (12 at Eel R., 12 at Hydrate ridge) to test settlement response to sulfides (use of gear elevator+sub). (2) collection of sediment in push cores/box cores for measurements of sulfide, sulfate reduction (35S), animal distributions/nutritional properties, shipboard incubation experiments with 13C tracers, nitrogen fixation, microbial consortia, sediment properties etc. (3) deployment and recovery of carbonate colonization substrates (4) large animal collections via biobox, scoop and slurp for nutritional studies (fatty acid, lipids, isotopes). (5) photographic surveys of seep and carbonate epifauna/habitat structure (6) rock collections (carbonates) Night operations will include extensive CTD casts and water sampling + multicoring transects across the oxygen minimum zones off CA/OR (400-1200 m).
