| Repeating Cruise Comments: |
|
| Justification/Comments: |
--- June 21: 12 days approved by NSF per L. Goad
--- Update June 18: I am requesting an increase in the science days from 10 to 12 and hope this is acceptable from a scheduling viewpoint and does not wreak havoc. Our work program and the program of our MPI collaborators has become more ambitious since we realized the potential of this cruise. The MPI is interesting in bringing in-situ devices (chemical gradient profilers; benthic chambers, planar optodes) that allow unprecedented detail in measurements of in-situ microbial process rates and geochemical gradients; all this will benefit greatly from more bottom time. |

PI-Provided Vans - briefly describe
|
| Instrumentation Comments: |
We need a -80C freezer for sample storage, and a contained area (radioactivity van) for work with radiotracers (35S-sulfate, 14C-methane), all of them weak beta-emitters.
--- A large minus 80C freezer for sample storage would be optimal; we will have lots of samples for molecular biology work that have to be frozen immediately. Otherwise, we can improvise with -20 chest freezers and load them with dry ice for colder temperatures.
--- For sediment sampling: If there are thermometers or thermosensors for Alvin or JASON use, we would need them for measuring the temperature gradients in hydrothermally active sediment s before coring.
--- A contained area (radioisotope van) for work with radiotracers (35S-sulfate, 14C-methane) and temporary waste storage (until end of cruise) is needed.

| Ancil Facilities Requested: |
Alvin
Other ROV
|
| Ancil Facility Comments: |
--- We have to look into using an ROV for in-situ sulfate reduction work using radiotracers, since radionucleotides are prohibited on ALVIN.
--- Update June 18, 2007: After consulting with our German collaborators and other ALVIN and ROV (JASON) users, it is clear that we can perform our program of sediment sampling and in-situ process measurements just as well or even better with JASON and an elevator; the advantage of more bottom time with JASON would outweigh the greater maneuverability of ALVIN. If possible, JASON and an elevator platform for transporting samples and in-situ equipment are preferred. |
