The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life , such as sea stars , sea urchins , and many species of coral with regional differences ...
A rock, seen at low tide, exhibiting typical intertidal zonation. A specimen of the shell Pinna nobilis exposed by low tide. Because intertidal organisms endure regular periods of immersion and emersion, they essentially live both underwater and on land and must be adapted to a large range of climatic conditions.
A global analysis of tidal wetlands (mangroves, tidal flats, and tidal marshes) published in 2022 estimated global losses of 13,700 km 2 (5,300 sq mi) from 1999-2019, however, this study also estimated that these losses were largely offset by the establishment of 9,700 km 2 (3,700 sq mi) of new tidal wetlands that were not present in 1999. [263]
As the water recedes, it uncovers more and more of the foreshore, also known as the intertidal zone. The difference in height between the high tide and low tide is known as the tidal range or tidal amplitude. [65] [66] Most places experience two high tides each day, occurring at intervals of about 12 hours and 25 minutes.
Tidal flows are important for navigation, and significant errors in position occur if they are not accommodated. Tidal heights are also important; for example many rivers and harbours have a shallow "bar" at the entrance which prevents boats with significant draft from entering at low tide.
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
The most apparent character of the area is the development of tidal channels, affecting mainly the intertidal zone. In this case, the tidal flat is protected seaward by a beach barrier, but in many cases (low-energy waves and longshore currents) the tidal flats may directly pass into a shallow marine environment.
The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore. [1] In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely inundated), to coastal areas that are permanently submerged — known as the foreshore — and the terms are often used interchangeably.
