tidal gauges

Tidal gauges are scientific instruments used to measure the rise and fall of sea levels over time. They typically consist of a sensor or float placed in a tide station that tracks water level changes, often connected to a graduated scale or electronic recording device. These measurements help monitor daily tide cycles, assess long-term sea level trends, and understand the impacts of climate change and tides. Tidal gauge data is vital for coastal planning, navigation, and studying oceanographic and climate phenomena.
