The Norwegian Polar Institute would like conductivity temperature depth (CTD) instruments for measuring seawater temperature, conductivity and pressure, which shall be implemented on permanent oceanographic vessels in observation systems in arctic or antarctic waters within ongoing and/or future monitoring and research projects.

The instruments should have the possibility for the integration of chlorophyll sensors and/or other sensors.

The estimated need is 10 instruments during a four-year period. The need may change in the event of loss of instruments.
