What is the fastest ocean current?
Gulf StreamGulf Stream Velocity.
The Gulf Stream is the fastest ocean current in the world with peak velocities near 2m/s.
Shown to the left are velocity profiles across the Gulf Stream at the Straits of Florida and Cape Hatteras..

How deep in the ocean have we been?
At 5:52 p.m. ET Sunday (7:52 a.m. Monday, local time), James Cameron arrived at the Mariana Trench’s Challenger Deep, members of the National Geographic expedition have confirmed. His depth on arrival: 35,756 feet (10,898 meters)—a figure unattainable anywhere else in the ocean.
Why is ocean water salty?
Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. … Ocean water seeps into cracks in the seafloor and is heated by magma from the Earth’s core.
What is a gyre in the ocean?
A gyre is a large system of rotating ocean currents. Together, these larger and more permanent currents make up the systems of currents known as gyres. … There are five major gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre.
What are 2 types of ocean currents?
There are two type of Ocean Currents:Surface Currents–Surface Circulation.Deep Water Currents–Thermohaline Circulation.Primary Forces–start the water moving.The primary forces are:Secondary Forces–influence where the currents flow.Solar heating cause water to expand.More items…
What are the 5 major ocean currents?
There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).
Can a whirlpool sink a ship?
A tidal whirlpool can sink a container ship. In order for this to happen, the whirlpool would have to be significantly stronger than any maelstrom ever recorded.
Can you swim in a whirlpool?
When two water currents meet, they sometimes form a swirling, circular whirlpool. Whirlpools can be dangerous for swimmers and small boats, although larger ships aren’t at any real risk of being sucked into a whirlpool, even a particularly large and powerful one — which can also be called a maelstrom.
What part of the ocean is the deepest?

Why is 95 of the ocean unexplored?
The world’s five oceans have gone largely unexplored. … Because the oceans cover 71% of the planet’s surface, that means most of Earth has yet to be observed by humans.
Where does most of the heat in ocean water come from?
sunlightThe main source of ocean heat is sunlight. Additionally, clouds, water vapor, and greenhouse gases emit heat that they have absorbed, and some of that heat energy enters the ocean. Waves, tides, and currents constantly mix the ocean, moving heat from warmer to cooler latitudes and to deeper levels.
What is the largest whirlpool in the world?
Maelstrom of SaltstraumenThe Maelstrom of Saltstraumen is earth’s strongest Maelstrom. It is located close to the Arctic Circle, 33 km (20 mi) round the bay on Highway 17, south-east of the city of Bodø, Norway. The strait at its narrowest is 150 m (490 ft) in width and water “funnels” through the channel four times a day.
What percent of the world is ocean?
70 percentAbout 97 percent of Earth’s water is in the ocean. The ocean covers more than 70 percent of the surface of our planet. It’s hard to imagine, but about 97 percent of the Earth’s water can be found in our ocean. Of the tiny percentage that’s not in the ocean, about two percent is frozen up in glaciers and ice caps.
Which is the deadliest ocean?
REUTERS/Bobby Yip The South China Sea and East Indies, eastern Mediterranean, Black Sea, North Sea, and British Isles are the most dangerous seas in the world, with the greatest number of shipping accidents in the last 15 years, according to a report released by the World Wildlife Fund (WWF).
What would happen if ocean circulation stopped?
If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.
Which ocean currents are warm?
Warm ocean currents flow away from the equatorial region on the western side of ocean basins. The Gulf Stream in the North Atlantic and the Kuroshio Current in the North Pacific are examples of warm currents. Of all the warm currents, the Gulf Stream has been studied most extensively.
