The IHO limits of the Atlantic Ocean. This is a list of islands in the Atlantic Ocean, the largest of which is Greenland.Note that the definition of the ocean used by the International Hydrographic Organization (IHO) excludes the seas, gulfs, bays, etc., bordering the ocean itself. [1]
The first discovered mid-ocean ridge was the Mid-Atlantic Ridge, which is a spreading center that bisects the North and South Atlantic basins; hence the origin of the name 'mid-ocean ridge'. Most oceanic spreading centers are not in the middle of their hosting ocean basis but regardless, are traditionally called mid-ocean ridges.
The Atlantic Ocean excluding its Arctic and Antarctic regions. List of states and dependent territories with a coastline on the Atlantic Ocean — including the North, Baltic, Mediterranean, and Black Seas — (dependent territories italicized with the sovereign state bracketed).
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian plate and the African plate , north and south of the Azores triple junction .
The earliest phase of the seaway began in the mid-Cretaceous when an arm of the Arctic Ocean transgressed south over western North America; this formed the Mowry Sea, so named for the Mowry Shale, an organic-rich rock formation. [1] In the south, the Gulf of Mexico was originally an extension of the Tethys Ocean. In time, the southern embayment ...

Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.
The Juan de Fuca Ridge is a mid-ocean spreading center and divergent plate boundary located off the coast of the Pacific Northwest region of North America, named after Juan de Fuca. The ridge separates the Pacific Plate to the west and the Juan de Fuca Plate to the east. It runs generally northward, with a length of approximately 500 kilometres ...
