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 Gulf of Oman or Sea of Oman, also known as Gulf of Makran or Sea of Makran, is a gulf that connects the Arabian Sea with the Strait of Hormuz, which then runs to the Persian Gulf. It borders Iran and Pakistan on the north, Oman on the south, and the United Arab Emirates on the west.
The North Sea lies between Great Britain, Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 kilometres (600 mi) long and 580 kilometres (360 mi) wide, covering 570,000 square kilometres (220,000 sq mi).
Barbados is a continental island in the North Atlantic Ocean and is located at 13°10' north of the equator, and 59°32' west of the Prime Meridian. As the easternmost isle of the Lesser Antilles in the West Indies, Barbados lies 160 kilometres (100 mi) east of the Windward Islands and Caribbean Sea. The maritime claim for Barbados is a territorial sea of 12 nmi, with an exclusive economic zone of 200 nmi which gives Barbados a total maritime area of 186,898 km2 (72,162 sq mi). Of the total EEZ area, 70,000 km2 is set aside for offshore oil exploration. A pending application to UNCLOS has placed for consideration a continental shelf 200 nmi to the east and south. To the west, most of Barbados' maritime boundaries consist of median lines with neighbours. These neighbours include: Martinique, and Saint Lucia to the northwest, Saint Vincent and the Grenadines to the west, Trinidad and Tobago and Venezuela to the southwest, and Guyana to the southeast.
A coast guard or coastguard is a maritime security organization of a particular country. The term embraces wide range of responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue without law enforcement authority. In most countries, a typical coast guard's functions are distinct from those of the navy and the transit police, while in certain countries they have similarities to both.
The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia.
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine resources, including energy production from water and wind. EEZ does not define the ownership of any maritime features within the EEZ.
Responsibilities for traditional coast guard duties in Australia are distributed across various federal, state and community agencies. The de facto coast guard of Australia is the Maritime Border Command, a joint command of the Australian Defence Force and the Australian Border Force which works alongside the Australian Federal Police, the Australian Fisheries Management Authority, and the Australian Maritime Safety Authority. Each state and territory government have specific maritime safety agencies and police marine units. In addition, there are several private volunteer coast guard organisations which act as auxiliary search and rescue services and maritime safety educators with the largest organisations being the Royal Volunteer Coastal Patrol established in 1937, the Australian Volunteer Coast Guard established in 1961, and Marine Rescue New South Wales established in 2009.
The British Columbia Coast, popularly referred to as the BC Coast or simply the Coast, is a geographic region of the Canadian province of British Columbia. As the entire western continental coastline of Canada along the Pacific Ocean is in the province, it is synonymous with being the West Coast of Canada.
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.
Sailing Directions are written directions that describe the routes to be taken by boats and ships during coastal navigation and port approaches. There are also products known as Sailing Directions, which are books written by various Hydrographic Offices throughout the world. They are known as Pilot Books, because they provide local knowledge of routes and landmarks, which would typically be provided by a local marine pilot. As such, they are used frequently by naval and government vessels, who are exempted from 'Compulsory Pilotage' in many ports.
The Backstairs Passage is a strait in South Australia lying between Fleurieu Peninsula on the Australian mainland and Dudley Peninsula on the eastern end of Kangaroo Island. The western edge of the passage is a line from Cape Jervis on Fleurieu Peninsula to Kangaroo Head on Kangaroo Island. The Pages, a group of islets, lie in the eastern entrance to the strait. About 14 km wide at its narrowest, it was formed by the rising sea around 13,000 years ago, at the end of the Pleistocene era, when it submerged the land connecting what is now Kangaroo Island with the Fleurieu Peninsula. Backstairs Passage was named by Matthew Flinders whilst he and his crew on HMS Investigator were exploring and mapping the coastline of South Australia in 1802.
Western Australia has the longest coastline of any state or territory in Australia, at 10,194 km or 12,889 km. It is a significant portion of the coastline of Australia, which is 35,877 km.
The geography of Australia encompasses a wide variety of biogeographic regions being the world's smallest continent, while comprising the territory of the sixth-largest country in the world. The population of Australia is concentrated along the eastern and south-eastern coasts. The geography of the continent is extremely diverse, ranging from the snow-capped mountains of the Australian Alps and Tasmania to large deserts, tropical and temperate forests, grasslands, heathlands and woodlands.
The geography of Queensland in the north-east of Australia, is varied. It includes tropical islands, sandy beaches, flat river plains that flood after monsoon rains, tracts of rough, elevated terrain, dry deserts, rich agricultural belts and densely populated urban areas.
Blue Mud Bay is a large, shallow, partly enclosed bay on the eastern coast of Arnhem Land, in the Northern Territory of Australia, facing Groote Eylandt on the western side of the Gulf of Carpentaria. It lies 580 km (360 mi) east-south-east of Darwin in the Arnhem Coast bioregion. Its name was given to a landmark court ruling affirming that the Aboriginal traditional owners of much of the Northern Territory's coastline have exclusive rights over commercial and recreational fishing in tidal waters overlying their land.
