How to locate sensor calibration documents for OOI instruments

The calibration documents are stored in the OOI’s document management system called Alfresco, accessible here.

1. After clicking the access link to Alfresco above, you will be prompted to log-in using CILogon.

2. Once in Alfresco, click on Sites (tab at top) > Ocean Observatories Initiative.

3. Navigate to the main Document Library (tab in upper right).

4. From the top of the Documents directory, the file path to the calibration files is: Instrument & Platform Documents / Calibration and Repair. Calibration and Repair documents are organized by Cabled Array instrumentation or Coastal-Global Arrays (Endurance, Pioneer and Global instrumentation), and then by instrument class.

5. After choosing the instrument class from the Calibration and Repair folder, you will see individual files per instrument class-series, instrument serial number, and calibration date.

Specific information related to instruments (including serial numbers) is captured per deployment, per data stream. Reference this tutorial to find instrument serial numbers for your deployment(s) and instrument(s) of interest in Data Explorer.

The file naming convention for calibration files is generally [data series]_[instrument model]_[instrument serial number]_[calibration description keywords]_[calibration date], though there is some variation between instrument types.
