Low tide is measured using specialized instruments that record the height of the water relative to a fixed point on land.
Tide Gauges: The Standard Measurement Tool
The primary method for measuring low tide involves the use of tide gauges. These instruments are strategically placed in ports and harbors worldwide to monitor tidal fluctuations continuously. According to the provided reference, these gauges measure the height of the rising and falling tide relative to a fixed reference point:
- Reference Level: This reference point is a "benchmark" located on the nearby land.
How Tide Gauges Work
While the specific technology used in tide gauges can vary, they all essentially perform the same function: continuously recording water levels.
- The height of the water is tracked in relation to the benchmark.
- This recorded data provides a precise measurement of low tide, as well as other tidal stages.
In summary, low tide is precisely measured using tide gauges that continuously record the height of the water relative to a fixed benchmark on land.
