Tide Gauge

A tide gauge is a device used to measure the change in sea level over time. It records the height of the ocean surface against a fixed point, tracking tides, storm surges, and long-term sea level rise. Tide gauges can be found along coastlines and are vital for understanding coastal processes, climate change, and navigation safety. By analyzing the data collected, scientists can assess trends in sea level, which helps in planning for flooding, infrastructure resilience, and environmental conservation.
