Some key measurements include:

Measurement

Value

Area

Approximately 41 million sq mi (106.5 million sq km)

Average Depth

About 12,080 feet (3,682 meters)

Deepest Point

Around 27,500 feet (8,380 meters)

⭐ Did You Know?

The Atlantic Ocean becomes a little wider every year as North America and Europe slowly move away from each other.

What Bodies of Water Connect to the Atlantic Ocean?

The Atlantic Ocean connects with many important seas and oceans around the world.

Major connected waters include:

• Arctic Ocean
• Southern Ocean
• Caribbean Sea
• Gulf of Mexico
• Mediterranean Sea
• North Sea
• Baltic Sea
• Norwegian Sea
• Labrador Sea
• Celtic Sea

It also connects indirectly to:

• Indian Ocean around southern Africa

These connections make the Atlantic one of the busiest waterways on Earth.

Why Is the Atlantic Ocean Important?

The Atlantic Ocean is essential for life, transportation, weather, and the global economy.

It supports:

• International shipping
• Commercial fishing
• Offshore oil and natural gas
• Renewable energy projects
• Tourism
• Marine biodiversity
• Scientific research
• Climate regulation

Around 90% of global trade by volume travels by sea, and many of the world’s busiest shipping lanes cross the Atlantic.

The Atlantic also helps move heat around the planet through powerful ocean currents such as the Gulf Stream, which influences weather across North America and Europe.

⭐ Did You Know?

Without the Gulf Stream, much of Western Europe would be significantly colder than it is today.

What Is the Climate Like in the Atlantic Ocean?

The Atlantic Ocean has many climate zones because it stretches from the Arctic to Antarctica. Water temperatures and weather conditions change greatly from north to south.

Northern Atlantic

The North Atlantic has cold winters and mild summers. Sea ice forms in some northern areas near Greenland and the Arctic Ocean. Winter storms are also common.

Tropical Atlantic

The tropical Atlantic is warm throughout the year. Water temperatures usually range from 77°F to 86°F (25°C to 30°C). This region is where many Atlantic hurricanes begin to develop during hurricane season.

Southern Atlantic

The South Atlantic generally has cooler waters than the tropical Atlantic but is milder than the far south near Antarctica. Strong winds and large waves are common, especially farther south.

Southern Ocean Region

Near Antarctica, the Atlantic becomes extremely cold. Icebergs, sea ice, and freezing temperatures are common for much of the year.

Major Ocean Currents

Several powerful currents influence the Atlantic Ocean’s climate.

• Gulf Stream
• North Atlantic Current
• Canary Current
• Brazil Current
• Benguela Current
• Labrador Current

These currents move warm and cold water around the world, helping regulate global temperatures.

⭐ Did You Know?

The Gulf Stream can move water at speeds of up to about 5.6 mph (9 km/h) in some areas, making it one of the fastest major ocean currents.

What Animals Live in the Atlantic Ocean?

The Atlantic Ocean is home to thousands of marine species, from tiny plankton to the world’s largest animals.

Marine Mammals

Many whales and dolphins migrate through the Atlantic each year.

Common species include:

• John Cabot exploring parts of North America
• Ferdinand Magellan’s expedition crossing the Atlantic before sailing around the world

These journeys changed global trade and connected continents in new ways.

The Mid-Atlantic Ridge

One of the Atlantic’s most remarkable features is the Mid-Atlantic Ridge, an underwater mountain range that runs nearly the entire length of the ocean.

Key facts include:

• More than 10,000 miles (16,000 km) long
• Formed by tectonic plates moving apart
• Creates new ocean floor through volcanic activity
• Includes Iceland, where parts of the ridge rise above sea level

The Bermuda Triangle

The Bermuda Triangle is a region in the western North Atlantic often linked to mysterious stories about ships and aircraft.

However, scientific studies have found no evidence that this area experiences more unexplained disappearances than other heavily traveled parts of the ocean. Most incidents can be explained by weather, navigation challenges, mechanical problems, or human error.

Major Shipping Routes

The Atlantic Ocean carries some of the busiest shipping lanes in the world.

Common cargo includes:

• Food products
