The coast, also known as the coastline 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.
County Donegal is a county of Ireland in the province of Ulster and in the Northern and Western Region. It is named after the town of Donegal in the south of the county. It has also been known as County Tyrconnell, after the historic territory. Donegal County Council is the local council and Lifford is the county town.
County Cork is the largest and the southernmost county of Ireland, named after the city of Cork, the state's second-largest city. It is in the province of Munster and the Southern Region. Its largest market towns are Mallow, Macroom, Midleton, and Skibbereen. As of 2022, the county had a population of 581,231, making it the third-most populous county in Ireland. Cork County Council is the local authority for the county, while Cork City Council governs the city of Cork and its environs. Notable Corkonians include Michael Collins, Jack Lynch, Roy Keane, Sonia O'Sullivan, Cillian Murphy, and Graham Norton.
Ireland is an island in Northern Europe in the north Atlantic Ocean. The island lies on the European continental shelf, part of the Eurasian Plate. The island's main geographical features include low central plains surrounded by coastal mountains. The highest peak is Carrauntoohil, which is 1,039 metres (3,409 ft) above sea level. The western coastline is rugged, with many islands, peninsulas, headlands and bays. The island is bisected by the River Shannon, which at 360.5 km (224 mi) with a 102.1 km (63 mi) estuary is the longest river in Ireland and flows south from County Cavan in Ulster to meet the Atlantic just south of Limerick. There are a number of sizeable lakes along Ireland's rivers, of which Lough Neagh is the largest.
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.
Dublin Bay is a C-shaped inlet of the Irish Sea on the east coast of Ireland. The bay is about 10 kilometres wide along its north–south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sand banks lay, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.
The Gulf of Maine is a large gulf of the Atlantic Ocean on the east coast of North America. It is bounded by Cape Cod at the eastern tip of Massachusetts in the southwest and by Cape Sable Island at the southern tip of Nova Scotia in the northeast. The gulf includes the entire coastlines of the U.S. states of New Hampshire and Maine, as well as Massachusetts north of Cape Cod, and the southern and western coastlines of the Canadian provinces of New Brunswick and Nova Scotia, respectively.
Árainn Mhór is an island off the west coast of County Donegal, Ireland. Arranmore is the largest inhabited island of County Donegal, with a population of 478 in 2022, but has had a gradually falling native population since the 1990s. Its main settlement is Leabgarrow. The island is part of the Gaeltacht, with most of the inhabitants speaking Ulster Irish.
Coastal and offshore rowing is a rowing sport performed at sea. In North America, this sport is often called open water rowing.
The coastline of the United Kingdom is formed by a variety of natural features including islands, bays, headlands and peninsulas. It consists of the coastline of the island of Great Britain, the north-east coast of the island of Ireland, as well as many much smaller islands. Much of the coastline is accessible and quite varied in geography and habitats. Large stretches have been designated areas of natural beauty, notably the Jurassic Coast and various stretches referred to as heritage coast. They are both very long, spreading through the mainland.
The geology of Ireland consists of the study of the rock formations on the island of Ireland. It includes rocks from every age from Proterozoic to Holocene and a large variety of different rock types is represented. The basalt columns of the Giant's Causeway together with geologically significant sections of the adjacent coast have been declared a World Heritage Site. The geological detail follows the major events in Ireland's past based on the geological timescale.
The fauna of Ireland comprises all the animal species inhabiting the island of Ireland and its surrounding waters.
The following outline is provided as an overview of and introduction to Oceanography.
The climate of Ireland is mild, humid and changeable with abundant rainfall and a lack of temperature extremes. Ireland's climate is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of northwest Europe. The island receives generally warm summers and cool winters.
Broadhaven Bay is a natural bay of the Atlantic Ocean on the northwestern coast of County Mayo, Ireland. The opening of the bay faces northward, stretching 8.6 km between Erris Head in the west and Kid Island/Oileán Mionnán in the east.
Banagh is a historic barony in County Donegal in Ireland. Patrick Weston Joyce said the name Banagh came from Enna Bogaine, son of Conall Gulban, son of Niall of the Nine Hostages. It was created along with Boylagh when the former barony of Boylagh and Banagh was split in 1791 by an Act of the Parliament of Ireland.
Ireland has become increasingly popular as a surfing destination, due to its exposed location on the turbulent Atlantic seaboard. Irish surf culture was further introduced in Australia by Sinead.
The marine protected areas of South Africa are in an area of coastline or ocean within the exclusive economic zone (EEZ) of the Republic of South Africa that is protected in terms of specific legislation for the benefit of the environment and the people who live in and use it. An MPA is a place where marine life can thrive under less pressure than unprotected areas. They are like underwater parks, and this healthy environment can benefit neighbouring areas.
