Summary

The Atlantic Ocean, the second-largest of the world's five oceans, covers approximately 17% of Earth's surface and plays a pivotal role in human history and global trade. Its S-shaped basin stretches between Europe and Africa to the east and the Americas to the west, connecting to the Arctic, Pacific, Indian, and Southern Oceans. Historically, it separated the "New World" from the "Old World," and following Christopher Columbus's 1492 expedition, it became central to European exploration, colonization, the slave trade, and the Columbian Exchange. Today, the Atlantic remains a crucial artery for international commerce, with its temperatures varying from the consistently warm South Atlantic to the temperate North Atlantic. Recent scientific observations have highlighted alarming ocean warming trends in the Atlantic, with temperatures exceeding those recorded during the 2005 Hurricane Katrina season, potentially linked to shipping emission regulations.

Atlantic Ocean

The Atlantic Ocean is the second largest of the world's five oceanic divisions, 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 (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and the Columbian exchange while occasionally hosting naval battles. Such naval battles, as well as growing trade from regional American powers like the United States and Brazil, both increased in degree during the early 20th century, and while no major military conflicts have taken place in the Atlantic recently, the ocean remains a core component of trade around the world. The Atlantic Ocean's temperatures vary by location. For example, the South Atlantic maintains warm temperatures year-round, as its basin countries are tropical. The North Atlantic maintains a temperate climate, as its basin countries are temperate and have seasons of extremely low temperatures and high temperatures. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and the Americas to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, 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 Atlantic Ocean is divided in two parts, the northern and southern Atlantic, by the Equator.

    The Atlantic Ocean is the second largest ocean on Earth, covering approximately 85.133 million square kilometers, with an additional 23 million square kilometers contributed by its dependent seas. It separates the Americas from Europe and Africa and is commonly divided into the North and South Atlantic. The ocean has an average depth of 3,300 meters and a maximum depth of 8,380 meters. Its formation dates back over 200 million years, originating from the breakup of the supercontinent Pangaea, [...] The Atlantic Ocean, with an average depth of 3,300 meters and a maximum depth of 8,380 meters, touches the eastern coastlines of North and South America and the western coastlines of Europe and Africa. The Atlantic Ocean is often divided into the North Atlantic and the South Atlantic, although the entire oceanic mass may properly be considered a single ocean. The North Atlantic extends from the equator north to the Arctic Ocean. The South Atlantic, that part of the ocean south of the equator [...] Close to shore, the Atlantic Ocean is generally shallow, seldom exceeding a depth of 545 meters. Waters cover a shelf of rock that, in most of the North Atlantic, extends between 65 and 80 kilometers from the coastline into the ocean. At the end of this shelf, the ocean drops precipitously to a depth of about 3,940 meters, gradually leveling off into what is designated the abyssal plain. The continental shelf off the coast of Africa is much narrower than the continental shelf off the coast of
