Kayaking in an estuary can be a fascinating and educational experience. Estuaries are transitional zones where freshwater rivers meet the saltwater of the ocean. They are highly dynamic and productive ecosystems that support a diverse array of plant and animal species.

One of the most striking features of estuaries is the tidal cycle, which is caused by the gravitational pull of the moon and the sun. Tides occur as the water level rises and falls in response to these gravitational forces. During high tide, water from the ocean flows into the estuary, flooding the area and creating a brackish environment where freshwater mixes with seawater. This influx of water brings in nutrients and sediments from the ocean, which are essential for the productivity of the estuarine ecosystem.

As you experienced during your kayaking trip, the movement of the tide can be quite dramatic. The transition from high tide to low tide can happen relatively quickly, and the change in water level can be significant. This tidal movement exposes various features of the estuary, such as mudflats, salt marshes, and tidal channels.
