    Science objectives/activities planned:
• Recover colonization experiments on Mound 12 (carbonate, wood, tubeworms, shells). Processs these at sea.
• Background collections of wood, active carbonate (especially dolomite) rock and biotic (mussel, tube) substrates
• Characterization of chemical regimes at colonization sites
• Possible Archaea C fixation/ production experiments with 13C or 15N2 using background or colonizer fauna
• ALVIN CTD and water sampling at active and inactive seep sites having colonization experiments.

• Coring seep (mat, clam) sediments in specific locations across a range of O2 levels if time.
• Follow-up collection of new species (including yeti crabs, folliculinid cilliates, mussels, clams, crustaceans, annelids etc)
*collection of microbial mat on rocks
* Revisit Jaco scarp.. sample tubeworm bushes and other fauna
Night Operations:
* Nighttime off seep CTD casts with Rosette to examine ENSO signals and compare to 2009
* Multibeam mapping as needed (pre dive)
