Conclusions • Potential for 3 new groups (phyla) of Bacteria!! • Something is happening with N!! • Community shift pre- verses packed- drill holes. • Surprising diversity for a subsurface. • Low abundance of both Archaea and Eucarya! • Publish?
Thanks To: • My Start-up money…. • Team Bio--Tom K., Jeff M., Alexis T., Betsy S., Jeff W., Kevin M. • HUSEP Folks • Henderson Mine and Chip deWolfe
“If it wasn’t for the optimist, the pessimist would never know…. how happy he wasn’t.”
Henderson, New Drill Core • Plan, to drill a core into the HUSEP facility area • For some portion of that: • Take a segment for biological consideration • Sterile? BEADS + Tracer • Core collection--on site • Core sample sections to Socorro, CSM, CU • Continue drilling to depth
