The Piri Reis map's coastlines (outlined in black) are laid over the 1502 Cantino Planisphere, an earlier portolan world map. They show similarities and increased detail on Piri Reis' South American coast. The peculiar configuration of the Caribbean is usually attributed to the usage of an early map of Columbus, now lost.

Maps exhibiting the world's oceanic waters. A continuous body of water encircling Earth, the World/Global Ocean is divided into a number of principal areas. Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.
Mercator's 1569 map was a large planisphere, [3] i.e. a projection of the spherical Earth onto the plane. It was printed in eighteen separate sheets from copper plates engraved by Mercator himself. [4]
The presence of the Drake Passageway allows the three main ocean basins (Atlantic, Pacific and Southern) to be connected via the Antarctic Circumpolar current (ACC), the strongest oceanic current, with an estimated transport of 100–150 Sv (Sverdrups, million m 3 /s). This flow is the only large-scale exchange occurring between the global ...
This would make the Saint-Bélec slab the oldest known map of a territory in the world. According to the authors, the map probably was not used for navigation, but rather to show the political power and territorial extent of a local ruler's domain of the early Bronze Age. [1] [2] [3] [4]
The Louisville Ridge stretches diagonally across this bathymetric map of the southwest Pacific Ocean towards the Pacific-Antarctic Ridge at right bottom The Pacific-Antarctic Ridge (PAR, Antarctic Pacific Ridge, South Pacific Rise, South Pacific Ridge) [ 4 ] is a divergent tectonic plate boundary located on the seafloor of the South Pacific ...
The Antarctic plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau, and some remote islands in the Southern Ocean and other surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea ), the Antarctic plate began moving the continent of Antarctica south to its present ...
Dalrymple's chart of the South Pacific showing discoveries made before 1764 [13] The arguments he presents include reported sightings of the continent, areas known from previou exploration to be open water, and observations of wind, on the assumption that in open ocean winds will be constant, while variable winds indicate the preesence of a ...
