Instrumentation and sensor development
Long term continuous monitoring of hydrogeologic properties in
Project Manager: Hans Jannasch

This will be the second 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. Five custom boreholes will be
drilled and outfitted with numerous OsmoSamplers and other instruments.
In 2003, we
will review the design and deployment of the redeployable OsmoSamplers and pressure-maintaining
A-CORKs and make appropriate changes to the
design. Towards the end of the year, we will begin production of a
second set of OsmoSamplers to replace the initial set in early 2004.
