These broad embankments, which lie at depths of some 8, to 15, feet 2, to 4, metres at the foot of continents, reach more than miles km in width off northwestern Africa, AngolaArgentinaand the Eastern Seaboard of the United States. Thousands of core samples of marine sedimentsome more than feet 40 metres in length, have been collected in the North and South Atlantic by means of piston-coring tubes.

Ferdinand Magellanwho passed through the Strait of Magellan inassumed that the islands of Tierra del Fuego to the south were an extension of this unknown southern land.

Ocean Basins

Iceland, which rises from its crest, is rent by an extension of the median rift valley. There are no universally accepted boundary conventions. At lower latitudes, the ice melts during the summer months. These courses also include practical exercises in Visit Board Search and Seizure at sea which tend to be quite complex operations.

The prevailing surface winds over the tropical ocean are the trade winds that blow persistently from the northeast toward the southwest in the Northern Hemisphere and from the southeast toward the northwest in the Southern Hemisphere.

This includes its marginal seas: The thinner surface layer permits more nutrient-rich waters from deeper in the ocean to move upward into the photic zone, thereby increasing productivity in these regions.

Exploration of the Southern Ocean was inspired by a belief in the existence of a Terra Australis — a vast continent in the far south of the globe to "balance" the northern lands of Eurasia and North Africa — which had existed since the times of Ptolemy.Atlantic Ocean Basin The Atlantic Ocean is the second largest of Earth's five oceans, the most heavily traveled, and the most intensely studied, principally because of its importance in ship traffic between Europe and North America.

Indian Ocean

Indian Ocean: Indian Ocean, body of salt water covering approximately one-fifth of the total ocean area of the world. It is the smallest, youngest, and physically most complex of the world’s three major oceans.
