Science Objectives

Secure borehole CORKs for subsequent drilling Expedition 327 (JULY 5 TO Sept 5).
Download pressure data
Collect fluids from CORK fluid delivery lines for geochemical (inorganic and organic) and molecular biology studies.

Science Activities

  1. Collect basement fluids from 1301A using Mobile Pumping System (MPS) and Large Volume Bag Sampler (LVBS).
  2. Collect Gas-Tight samples from 1301A using MPS
  3. Deploy Large Volume In Situ Filtration (LVISF) to 1301A for overnight+ filtration of large volumes.
  4. Attempt collection of fluids from 1301B using MPS and LVBS and Gas-Tights
  5. Remote flushing of fluids from 1025C using MPS and LVBS and Gas-Tights
  6. Collect fluids from 1301A, 1301B, 1025C, 857D?, 1026B, with Ti-Majors and Syringe samplers as available and possible.
  7. Collect fluids at 1026B using MPS and LVBS,
  8. Deploy GeoMICROBE sled at 1301A for short (few days) early part of cruise
  9. Deploy GeoMICROBE sled to 1026B (latter half of cruise, but not at end)

10.  Download pressure data from 1301A and 1301B

11.  Lift dive weights from top plug at 1301B, place on 1301A

12.  Verify positioning of valves for subsequent drilling expedition

13.  Recover 3 well-head OsmoSampler (with MBIO experiment) from 1301B

14.  Redeploy 3 well-head OsmoSampler (with MBIO experiment) at 1301B

15.  Probably recover 3 well-head OsmoSampler (no MBIO experiment) from 1301A

16.  Probably redeploy 3 well-head OsmoSampler (with MBIO experiment) at 1301A

17.  Download pressure data from 857D

18.  Download pressure data from 1024C

19.  Download pressure data from 1025C before and after ubio pumping/sampling
