How are instruments calibrated?

All OOI sensors are calibrated prior to deployment and subjected to pre-deployment testing. Additionally, during OOI deployment/recovery cruises, hydrographic rosette casts are conducted and water samples are collected for cross-calibration of specific parameters. These data are accessible to all users.

Instruments are turned over and replaced with new or refurbished units on a standard scheduled that varies by platform and array. The current OOI refurbishment schedule is contained in section 3.4 (“Platform Service Intervals”) of the OOI Observation and Sampling Approach document (#1102-00200). This schedule is subject to change as the system matures and more information is gained about platform and instrument longevity.
