TIDE GAUGE Meaning and
Definition
-
A tide gauge is a measuring instrument used to determine and record the height of ocean tides. It is a crucial tool for studying and monitoring changes in sea levels over time. The primary function of a tide gauge is to measure the vertical distance between the sea surface and a fixed reference point on land (usually known as Chart Datum).
The basic design of a tide gauge involves a long vertical column that is mounted either on a platform near the water's edge or directly in the water. At the bottom of this column is a pressure sensor or a float attached to a mechanical arm. As the tide rises and falls, the water pressure on the sensor or the buoyancy on the float changes, resulting in corresponding movements of the arm. These movements are then transformed into electrical signals, which are recorded and processed to determine the water level.
Tide gauges are equipped with highly sensitive sensors that can detect even subtle changes in sea level. They are often used in groups, forming a network of instruments to gather data across multiple locations. This data is important for assessing tidal patterns, predicting high and low tides, analyzing tidal cycles, and monitoring variations in sea level rise caused by climate change.
Tide gauges have been used for centuries and have evolved over time with advances in technology. Modern tide gauges are typically equipped with data loggers, which store and transmit information electronically. This allows for real-time monitoring and remote access to the data, enhancing the efficiency and accuracy of sea level measurements.

Etymology of TIDE GAUGE
The word "tide gauge" is composed of two elements: "tide" and "gauge".
The term "tide" comes from the Old English word "tīd", which means "time" or "season". This Old English word has Germanic roots and is related to the Old Norse word "tíð", meaning "time" or "period". Ultimately, both the Old English and Old Norse words trace back to the Proto-Germanic word "*tīdiz".
On the other hand, "gauge" is derived from the Old North French word "gauge", meaning "a measuring rod" or "standard of measurement". This Old North French term can be traced back to the Old Frankish word "galga" or "gaulge", which refers to a rod, staff, or pole.
