Tide gauge station

Japanese: 検潮場 - けんちょうじょう

Also written as tidal observation station. Tide observation is the continuous long-term observation of the height of the sea surface (tide level), which moves up and down with the tides, and the facilities set up for this purpose are called tide observation stations, and the instruments that automatically record the tide level are called tide observation instruments. Tide observation stations are generally constructed by guiding seawater through tubes into wells dug near the coast, so that the tide level can be observed inside the well without being disturbed by rain, wind, or waves. Two types of tide observation instruments are commonly used: buoy tide observation instruments and hydraulic tide observation instruments.

Japanese:

験潮場とも書く。潮の干満で上下に運動している海面の高さ(潮位)を，長期間連続して観測することを検(験)潮といい，そのために設けられた施設を検潮場，潮位を自動的に記録する器械を検(験)潮器(儀)という。検潮場は，海岸近くに掘られた井戸の中に管で海水を導き，雨風や波浪に妨げられることなく，井戸内で潮位の観測ができるようになっているのが一般的である。検潮器は，浮標式検潮器と水圧式検潮器の2種類がよく用いられる。
