Hoitoaikavälin

Hoitoaikavälin, also known as the Intertidal Zone or the Littoral Zone, is the area between the high and low tide marks on a shoreline. This dynamic environment is characterized by its frequent exposure to air and water, which creates a unique set of conditions that support a diverse range of plant and animal life. The intertidal zone is a critical habitat for many species, providing them with protection from predators and a rich source of food.

The intertidal zone is divided into several distinct zones based on the duration of exposure to air and water. The highest zone, known as the splash zone, is only exposed to air during the highest tides. Below this is the upper intertidal zone, which is exposed to air for a longer period but still submerged during high tides. The middle intertidal zone is exposed to air for about half of each tidal cycle, while the lower intertidal zone is submerged for most of the time but exposed to air during low tides.

The intertidal zone plays a crucial role in the global carbon cycle. Algae and other plants in this zone absorb carbon dioxide from the atmosphere and release oxygen, while the decomposition of organic matter in the sediment releases carbon dioxide. This process helps to regulate the Earth's climate and supports the health of marine ecosystems.

The intertidal zone is also an important area for human activities, including fishing, tourism, and recreation. However, it is also vulnerable to human impacts, such as pollution, habitat destruction, and climate change. Conservation efforts are underway to protect this valuable ecosystem and ensure its continued health and productivity.
