Costa Rican Osmosamplers (Long Term Continuous Monitoring of Hydrogeologic Properties in Instrumented Boreholes)

Project Manager: Hans Jannasch
Lead Scientist: Geoff Wheat

This will be the third year of a collaborative four-year NSF/ODP*-funded project to study sediment processes within the subduction zone off Costa Rica by using MBARI-developed OsmoSamplers to continuously monitor porewaters within the subducting sediments.

MBARI OsmoSamplers were deployed in Sept 2002 in a series of boreholes drilled on an ODP cruise (leg 205). These will be replaced by new OsmoSamplers in spring 2004. The new instruments are expected to be in place for four years.
