The Atlantic Ocean is the second-largest of the world's oceanic divisions. With a total area of about 106,400,000 square kilometres (41,100,000 sq mi), it covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. The first part of its name refers to Atlas of Greek mythology, making the Atlantic the "Sea of Atlas".
The oldest known mention of "Atlantic" is in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): Atlantis thalassa (Greek: Ἀτλαντὶς θάλασσα; English: Sea of Atlas). The term Ethiopic Ocean, derived from Ethiopia, was applied to the southern Atlantic as late as the mid-19th century. Before Europeans discovered other oceans, the term "ocean" itself was synonymous with the waters beyond the Strait of Gibraltar that we now know as the Atlantic. The early Greeks believed this ocean to be a gigantic river encircling the world.
The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Eurasia and Africa to the east, and the Americas to the west. As one component of the interconnected global ocean, it is connected in the north to the Arctic Ocean (which is sometimes considered a sea of the Atlantic), to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south. (Other definitions describe the Atlantic as extending southward to Antarctica.) The equator subdivides it into the North Atlantic Ocean and South Atlantic Ocean.
A seascape is a photograph, painting, or other work of art which depicts the sea, in other words an example of marine art. By a backwards development, the word has also come to mean the view of the sea itself, and be applied in planning contexts to geographical locations possessing a good view of the sea.
In the UK a seascape is defined in planning and land use contexts as a combination of adjacent land, coastline and sea within an area, defined by a mix of land-sea inter-visibility and coastal landscape character assessment, with major headlands forming division points between one seascape area and the next. This approach to coastal landscape planning was developed jointly by Government environmental bodies in Wales (UK) and Ireland in 2000 to assist spatial planning for (at that time new) offshore wind farm developments. The resulting "Guide to best practice in seascape assessment ", (Marine Institute, Ireland, 2001), have since been adapted and applied in Scotland (Scottish Natural Heritage, UK, 2004) and in England (Defra, 2005) and Wales (Countryside Council for Wales, 2009) for guidance to offshore wind farm developers and for carrying out spatial planning assessments.
