The Atlantic Ocean has underwater waterfalls, with the Denmark Strait cataract being the largest, dropping water three times higher than Angel Falls, Earth’s highest waterfall on land!
The Atlantic Ocean’s surface water moves in a giant circle called the North Atlantic Gyre, like a massive underwater merry-go-round that helps distribute heat and nutrients!
The largest animal ever known, the blue whale, swims in the Atlantic Ocean and can grow as long as three school buses placed end to end!
The Sargasso Sea in the Atlantic Ocean is the only sea without shores, bounded by ocean currents instead of land, and it’s full of floating seaweed that creates a unique habitat for marine life!
There are coral reefs in the Atlantic Ocean that are over 8,000 years old – they were growing while woolly mammoths were still walking the Earth!
The Atlantic Ocean hosts the world’s largest seaweed bloom, the Great Atlantic Sargassum Belt, which can stretch from West Africa to the Gulf of Mexico – it’s visible from space!
Some Atlantic Ocean squid can glow in the dark using special light-producing organs, creating their own underwater light show!
The Atlantic salmon can jump up to 12 feet (3.66 meters) out of water – that’s higher than a basketball hoop!
There are hydrothermal vents on the Atlantic Ocean floor that create environments where creatures can live without sunlight, using chemicals instead of light for energy!
The Atlantic Ocean has underwater forests of kelp that can grow up to 2 feet (61 cm) per day – faster than most land plants!
Hurricane waves in the Atlantic Ocean can be detected by seismometers on the ocean floor, creating a pattern that scientists call “ocean microseisms” – it’s like the ocean doing a tiny dance!
The temperature difference between the surface and deep waters of the Atlantic Ocean can be more than 30°C (86°F) – that’s like the difference between a hot summer day and your freezer!
The Atlantic Ocean sends rain to four continents by turning enough water into clouds each day to fill over 170 million Olympic-sized swimming pools!
The coldest part of the Atlantic Ocean, near Antarctica, can be 28.4°F (−2°C) – slightly below freezing, but the salt keeps it liquid!
Tropical storms in the Atlantic Ocean can release as much energy as 10,000 nuclear bombs in just one day!
The Atlantic Ocean creates its own clouds called “marine layer stratus” that can stretch for hundreds of miles – like a giant blanket over the water!
The ocean’s surface can be as warm as 86°F (30°C) near the equator – warmer than most swimming pools!
