متن کاملNew packer experiments and borehole logs in upper oceanic crust: Evidence for ridgeparallel consistency in crustal hydrogeological properties
[1] We report new drillstring packer permeability tests conducted during Integrated Ocean Drilling Program (IODP) Expedition 327 in upper oceanic basement in Hole U1362A on the eastern flank of the Juan de Fuca Ridge. Hole U1362A lies within a closely spaced array (40–2460 m separation) of six holes in well-sedimented 3.5–3.6 m.y. old crust that were drilled, tested, and instrumented with boreh...

متن کاملExpedition 301 synthesis: hydrogeologic studies
Integrated Ocean Drilling Program Expedition 301 was part of a long term series of operations and experiments focused on quantifying hydrogeologic, lithologic, biogeochemical, and microbiological properties, processes, and linkages in basaltic crust on the eastern flank of the Juan de Fuca Ridge. This paper summarizes peer-reviewed hydrogeologic studies published since the end of Expedition 301...
متن کاملTemperature and Redox Effect on Mineral Colonization in Juan de Fuca Ridge Flank Subsurface Crustal Fluids
To examine microbe-mineral interactions in subsurface oceanic crust, we evaluated microbial colonization on crustal minerals that were incubated in borehole fluids for 1 year at the seafloor wellhead of a crustal borehole observatory (IODP Hole U1301A, Juan de Fuca Ridge flank) as compared to an experiment that was not exposed to subsurface crustal fluids (at nearby IODP Hole U1301B). In compar...
