The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about 85,133,000 km2 (32,870,000 sq mi). It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas from the Old World of Afro-Eurasia.

The Norse exploration of North America began in the late 10th century, when Norsemen explored areas of the North Atlantic colonizing Greenland and creating a short term settlement near the northern tip of Newfoundland. This is known now as L'Anse aux Meadows where the remains of buildings were found in 1960 dating to approximately 1,000 years ago. This discovery helped reignite archaeological exploration for the Norse in the North Atlantic. This single settlement, located on the island of Newfoundland and not on the North American mainland, was abruptly abandoned.
