Full tide and low tides recorded at gauge station Herqueville

Tide gauges were deployed at three stations around the Cap de la Hague. They operated at a depth range of 0?10 m, accurate to 3 cm and with a resolution of 0.3 cm every 15 s. They were deployed from the coast, at depths close to the lowest low water level. A total of 685 tidal cycles were measured; the dates and levels of high and low waters were extracted.
