What is a tide gauge?
Quick Answer
A tide gauge is an instrument that measures the height of the sea level over time, especially the rise and fall of tides.
The Full Story
Tide gauges have been used for centuries and are essential for tracking sea level changes, coastal flooding, and long-term climate trends. Modern tide gauges may use floats, pressure sensors, or radar to record sea level precisely. They help scientists compare local sea level rise across different coastlines and support navigation and harbor management. Some of the longest continuous sea-level records in the world come from tide gauge stations.
