A tide gauge is a device used to measure the height of tides in oceans, seas, and large lakes. Other synonyms for tide gauge include sea level gauge, water level recorder, tide meter, and oceanographic buoy. Each of these synonyms has a slightly different use and purpose, but all are utilized to monitor tides and water levels in different bodies of water. Scientific research and ocean monitoring rely heavily on tide gauges to study and understand the ocean's impact on our planet. Consequently, it is essential to have accurate and reliable tide gauges to support coastal communities and mitigate the impact of natural disasters such as tsunamis and flooding.
