| Summary: | The Simple Cabled Instrument for Measuring Parameters in-situ (SCIMPI) is a
new borehole observatory instrument designed to study dynamic processes
below the seafloor. SCIMPI performs time series measurements of temperature,
pressure and electrical resistivity at a series of depths, tailored for
site-specific scientific objectives. SCIMPI's modular design enables
tailoring of the type, depth distribution, and frequency of measurements
based on the study goals and sediment characteristics. The first prototype
is designed for 300 m below the seafloor in soft sediment and 1500 m b.s.l.
However, SCIMPI could be tailored for deeper goals. The instrument can be
configured for autonomous or cabled observatory deployments and has
successfully undergone a number of tests, including pressure,
communications, battery life, and interfacing with other drill-ship
equipment. Here we discuss the design of the instrument, its capabilities,
and the testing process it has passed through during four years of development.
SCIMPI was successfully deployed on the Cascadia margin within the NEPTUNE
Canada observatory network during IODP Expedition 341S in May 2013. |
