A coastal path (or a littoral path) is a trail along a sea shore or a lake shore for pedestrians, and sometimes for cyclists or equestrians. Some coastal paths were originally created for use by customs or coastguard officials looking out for smugglers landing illicit goods. In modern times some routes have been developed for tourists, with ...
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Coastal biogeomorphology looks at the interaction between marine organisms and coastal geomorphic processes. [2] Biogeomorphology is a subdiscipline of geomorphology. This can include not only microorganisms and plants, but animals as well.
Definition (marine biology), context, extra terminology [ edit ] In marine biology , the neritic zone , also called coastal waters , the coastal ocean or the sublittoral zone , [ 3 ] refers to that zone of the ocean where sunlight reaches the ocean floor , that is, where the water is never so deep as to take it out of the photic zone .
Coastal geography is the study of the constantly changing region between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, climatology and oceanography) and the human geography (sociology and history) of the coast.
General characteristics of a large marine ecosystem (Gulf of Alaska). Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal ...
Coastal habitats are the most visible marine habitats, but they are not the only important marine habitats. Coastlines run for 380,000 kilometres, and the total volume of the ocean is 1,370 million cu km. This means that for each metre of coast, there is 3.6 cu km of ocean space available somewhere for marine habitats.
Coastal sediment transport (a subset of sediment transport) is the interaction of coastal land forms to various complex interactions of physical processes. [1] [2] The primary agent in coastal sediment transport is wave activity (see Wind wave), followed by tides and storm surge (see Tide and Storm surge), and near shore currents (see Sea#Currents) . [1]
