| description | Integrated Ocean Drilling Program (IODP) Expedition
327 (summer 2010) was designed to resolve the nature of
fluid-rock interactions in young, upper volcanic crust on the
eastern flank of the Juan de Fuca Ridge. Expedition 327
drilled, cased and cored two new basement holes, conducted
hydrogeologic experiments, and installed subseafloor
borehole observatories (<i>Circulation Obviation Retrofit Kits</i>,
CORKs). These CORKs were intended to allow borehole
conditions to recover to a more natural state after the dissipation
of disturbances caused by drilling, casing, and other
operations; provide a long-term monitoring and sampling
presence for determining fluid pressure, temperature, composition,
and microbiology; and facilitate the completion of
active experiments to resolve crustal hydrogeologic conditions
and processes. Expedition 327 was followed (summer
2011) by R/V <i>Atlantis</i> Expedition AT18-07, with the
remotely-operated vehicle (ROV) <i>Jason</i>, to service these
CORKs, collect subseafloor pressure data, recover and
deploy autonomous fluid and microbial samplers, collect
large volumes of borehole fluids, and initiate a cross-hole
hydrogeologic experiment using an electromagnetic flow
meter. In addition, <i>Atlantis</i> Expedition AT18-07 refurbished
an old CORK that could not be replaced during
IODP Expedition 327, completing a critical part of the
three-dimensional observation network that is currently
being used to monitor a large-scale, directional formation
response to long-term fluid flow from the crust.
