The coast, also known as the coastline, shoreline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the coastline. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore which is created. The Earth has around 620,000 kilometres (390,000 mi) of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor important ecosystems such as freshwater or estuarine wetlands, which are important for bird populations and other terrestrial animals. In wave-protected areas they harbor saltmarshes, mangroves or seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic species. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessile animals and various kinds of seaweeds. In physical oceanography, a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of 1–50 meters.
The geography of Mexico describes the geographic features of Mexico, a country in the Americas. Mexico is located at about 23° N and 102° W in the southern portion of North America. From its farthest land points, Mexico is a little over 3,200 km (2,000 mi) in length. Mexico is bounded to the north by the United States, to the west and south by the Pacific Ocean, to the east by the Gulf of Mexico, and to the southeast by Belize, Guatemala, and the Caribbean Sea. The northernmost constituent of Latin America, it is the most populous Spanish-speaking country in the world. Mexico is the world's 13th largest country, three times the size of Texas.
Ansel Easton Adams was an American landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed a system of image-making called the Zone System, a method of achieving a desired final print through a technical understanding of how the tonal range of an image is the result of choices made in exposure, negative development, and printing.
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural.
Beach nourishment describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach can reduce storm damage to coastal structures by dissipating energy across the surf zone, protecting upland structures and infrastructure from storm surges, tsunamis and unusually high tides. Beach nourishment is typically part of a larger integrated coastal zone management aimed at coastal defense. Nourishment is typically a repetitive process since it does not remove the physical forces that cause erosion but simply mitigates their effects.
A seawall is a form of coastal defense constructed where the sea, and associated coastal processes, impact directly upon the landforms of the coast. The purpose of a seawall is to protect areas of human habitation, conservation, and leisure activities from the action of tides, waves, or tsunamis. As a seawall is a static feature, it will conflict with the dynamic nature of the coast and impede the exchange of sediment between land and sea.
Goat Rock Beach is a sand beach in northwestern Sonoma County, California, United States. This landform is a sub-unit of Sonoma Coast State Beach, owned and managed by the State of California. At the northern terminus of Goat Rock Beach is the mouth of the Russian River, and the southern end of this crescent shaped expanse is the massive Goat Rock, an iconic outcrop of the Sonoma Coast, which is barely attached to the mainland by a narrow isthmus.
The California State Coastal Conservancy is a non-regulatory state agency in California established in 1976 to enhance coastal resources and public access to the coast. The CSCC is a department of the California Natural Resources Agency. The agency's work is conducted along the entirety of the California coast, including the interior San Francisco Bay and is responsible for the planning and coordination of federal land sales to acquire into state land as well as award grant funding for improvement projects. The Board of Directors for the agency is made up of seven members who are appointed by the Governor of California and approved by the California Legislature, members of the California State Assembly and California State Senate engage and provide oversight within their legislative capacity.
The Goleta Slough is an area of estuary, tidal creeks, tidal marsh, and wetlands near Goleta, California, United States. It primarily consists of the filled and unfilled remnants of the historic inner Goleta Bay about 8 miles (13 km) west of Santa Barbara. The slough empties into the Pacific Ocean through an intermittently closed mouth at Goleta Beach County Park just east of the UCSB campus and Isla Vista. The slough drains the Goleta Valley and watershed, and receives the water of all of the major creeks in the Goleta area including the southern face of the Santa Ynez Mountains.
Coastal management is defence against flooding and erosion, and techniques that stop erosion to claim lands. Protection against rising sea levels in the 21st century is crucial, as sea level rise accelerates due to climate change. Changes in sea level damage beaches and coastal systems are expected to rise at an increasing rate, causing coastal sediments to be disturbed by tidal energy.
The Coast Ranges of California span 400 miles (644 km) from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains.
Goleta Beach is a region of coastline located near Goleta, California, just east of the University of California, Santa Barbara (UCSB) campus. A portion of the shore of Goleta Bay is managed by the County of Santa Barbara, as the Goleta Beach County Park (GBCP). The beach itself is partly man-made as sand was spread onto an existing sandspit in 1945. The beach is a seasonal habitat for migrating shorebirds, including the snowy plover, an endangered species, and is occasionally closed due to nourishment efforts.
Mussel Rock is a rock formation on the coast of San Mateo County, California, offshore from Daly City. It consists of one large and numerous smaller rocks of a type known as a stack, where a headland is eroded unevenly, leaving small islands. The rock itself is located 15 meters from the shore of Mussel Rock Park and stands 18 meters tall.
Covehithe is a village and civil parish in the East Suffolk district of the English county of Suffolk. It lies on the North Sea coast around 4 miles (6.4 km) north of Southwold and 7 miles (11 km) south of Lowestoft. Neighbouring settlements include Benacre, South Cove and Frostenden.
Sonoma Coast State Park is a State of California property in Sonoma County consisting of public access use on lands adjoining the Pacific Ocean. This extent of beach runs from a coastal point about 4 miles (6 km) north of Jenner and continues for approximately 17 miles (27 km) to the south to terminate at Bodega Head. The property lies along State Route 1 and consists of a number of named beaches including Arched Rock Beach, Gleason Beach and Goat Rock Beach. The ecosystem consists of alternating sandy beaches and rocky shoreline, with a marine terrace extending above the entire extent with an upland California coastal prairie habitat.
Mark Massara is an American surfer, attorney, and environmental conservationist. He first gained a reputation in the surfing and environmental communities when he won a $5.6 million Clean Water Act violation, the second largest ever collected. Since that case, he has assisted nonprofit organizations, including Surfrider Foundation and Sierra Club, government agencies, and private sector enterprises in several high-profile coastal and ocean protection, restoration, education and development campaigns that highlight and achieve coastal conservation and amenities for wildlife and future generations.
Coastal California, also known as the California Coastline and the Golden Coast, refers to the coastal regions of the U.S. state of California. The term is not primarily geographical as it also describes an area distinguished by cultural, economic and political attributes.
Gwbert, also known as Gwbert-on-Sea, is a cliff-top coastal village in Y Ferwig community, Ceredigion, Wales. It lies at the most southerly coastal point of Ceredigion, on the eastern shore of the Teifi estuary, from where there are views westwards over Cardigan Bay, and south-westwards to Poppit Sands and the headland of Cemaes Head, in neighbouring Pembrokeshire. It is reached by the B4548 road from the town of Cardigan, 2.8 miles (4.5 km) away.
The Streisand effect is an unintended consequence of attempts to hide, remove, or censor information, where the effort instead backfires by increasing awareness of that information. It is named after American singer and actress Barbra Streisand, whose attempt to suppress Kenneth Adelman's website publication of his photograph of her cliff-top residence in Malibu, California, taken to document California coastal erosion, inadvertently drew far greater attention to the previously obscure photograph in 2003.
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation. Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides. Slow-onset hazards, such as erosion and gradual inundation, develop incrementally over extended periods.
