Tidal patterns are greatly influenced by the size, shape, depth, and location of the ocean basin in which the tides occur.

Tidal movements result mainly from the pull of the moons gravity on the ocean.

Feeding and mating could be tied to tidal cycles for several organisms that occupy tidal basins or shorelines.
A tidal basin is typically marked by a yellow buoy. This color indicates areas where tidal conditions may affect navigation and is part of the U.S. Aids to Navigation System. Yellow buoys can signify various marine features, including tidal basins, but it's essential to refer to local navigation charts for specific meanings.
High ocean tides are not exactly 12 hours apart because the Earth rotates within the gravitational field of the moon, causing the tidal bulges to shift slightly every day. This leads to a tidal cycle that is typically around 12 hours and 25 minutes, known as the semidiurnal tide pattern. Multiple factors, such as the shape of coastlines and ocean basins, can also influence the timing and intensity of tides.
A tidal wave, also known as a tsunami, is caused by underwater earthquakes, volcanic eruptions, or landslides that displace a large amount of water. Unlike regular waves, which are caused by wind, tsunamis have much longer wavelengths and can travel across entire ocean basins at high speeds.

Tides primarily affect water levels, currents, and sediment movement in tidal waters. They play a significant role in shaping coastal landscapes, influencing marine life behavior, and providing opportunities for activities like surfing and fishing. Tidal fluctuations can also impact navigation and infrastructure in these areas.
