Crozet tide gauge (-46° 25.5′ South, 51° 52.2′ East) is settled on the Possession island in Crozet archipelago. It was installed in 1995.

It contains a DTINSU automatic tide gauge station which activates, every 20 mn, measurements of:
- atmospheric pressure with a Vaisala sensor;
- bottom pressure with a Paroscientific sensor, sea water temperature and conductivity with an Aanderaa sensor.Measurements are real time transmitted, via Argos system, to LEGOS.
