A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. These pools typically range from a few inches to a few feet deep and a few feet across. [ 1 ] Many of these pools exist as separate bodies of water only at low tide , as seawater gets trapped when the tide recedes.
A California tide pool in the low tide zone. The intertidal region is an important model system for the study of ecology, especially on wave-swept rocky shores. The region contains a high diversity of species, and the zonation created by the tides causes species ranges to be compressed into very narrow bands.
Tide pools with sea stars and sea anemone in Santa Cruz, California In addition to being shaped by aspects of climate, intertidal habitats—especially intertidal zonation patterns—are strongly influenced by species interactions, such as predation, competition, facilitation, and indirect interactions.
The water stops rising, reaching a local maximum called high tide. Sea level falls over several hours, revealing the intertidal zone; ebb tide. Oscillating currents produced by tides are known as tidal streams or tidal currents. The moment that the tidal current ceases is called slack water or slack tide. The tide then reverses direction and is ...
Swimming pool: an artificial container filled with water intended for swimming. Tank (or stock tank, Texas) an artificial pond, usually for watering cattle or other livestock. [40] Tarn: a mountain lake or pool formed in a cirque excavated by a glacier. Tide pool: a rocky pool adjacent to an ocean and filled with seawater. Tributary or affluent
Even if the tide schedule is favorable, rough winds and rain can make these trips treacherous. Make sure you are wearing sturdy shoes with a good tread, as wet rocks, kelp, and other sea materials ...
The Ballantine scale is a biologically defined scale for measuring the degree of exposure level of wave action on a rocky shore. Devised in 1961 by W. J. Ballantine, then at the zoology department of Queen Mary University of London, London, U.K., the scale is based on the observation that where shoreline species are concerned "Different species growing on rocky shores require different degrees ...
