Saint-Paul tide gauge (-38° 42.7′ South, 77° 32.3′ East) s situated in the crater of a partially immersed volcano which communicates with ocean. It was installed in 1994.
It contains a PM36S MarArgos automatic tide gauge station which activates, every 20 mn, measurements of:
– atmospheric pressure with a Vaisala sensor;
– bottom pressure, sea water temperature and conductivity with an Aanderaa WLR7 sensor.Measurements are real time transmitted, via Argos system, to LEGOS.
