SPM1.22 - Opportunity and requirements for ocean in-situ sensors - NeXOS

Session Objective

The session was made apparently for collecting user requirements for the NeXOS project, a questionnaire has been distributed to attendands.

Requirements are referred to sensor networks in terms of the development of new sensors.

Discussion summary

• scientists practices and experiences shall be taken into account during the design of new sensors
• sometimes instruments are very precise but not robust enough for the purpose of time series analysis
• sensor cost should be calculated taking into account all the life-cycle of it (maintanance, calibration,...)
• sensors should be intelligent enough:
  • to geolocate themselves
  • detect major faults
  • track changes
  • change metadata while changing status

• MD should be more comprehensive as data are used for purposes not foreseen when sensors are deployed
• no clear and unified strategy for calibration hampers the use of data
• extending the life time of sensors
• remotely addressable instruments
• consider and record the full deployment/operation environment (in MD)
