What is the temperature of the Antarctic Circumpolar Current?
The mean ACC temperature ranges from -1 to 5°C, depending on the time of year and location. The mean surface salinity decreases poleward, in general, from 34.9 at 35°S to 34.7 at 65°S. Typical salinity values are between 33.5 and 34.7, poleward of 65°S.
Is the Antarctic Circumpolar Current warm?
The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet.
Is the Antarctic current cold or warm?
Very Cold and Very Far Away: a Frozen Continent and Its Importance. Antarctica—the huge landmass at the South Pole—is the only continent that nobody lives on permanently (Figures 1A–D). It is very cold—the average temperature is -10°C (14°F) near the coast and -60°C (-76°F) in the interior.
How fast is the South Atlantic Current?
Its initial velocity is 15 miles per day, rising while it heads west, having a maximum of 60 miles per day.
What is the most powerful ocean current?
Antarctic Circumpolar Current
The Antarctic Circumpolar Current is the planet’s most powerful and arguably most important current. It is the only current to flow clear around the globe without being diverted by any landmass.
What is the biggest ocean current in the world?
Notorious among sailors for its strength and the rough seas it creates, the Antarctic Circumpolar Current (ACC) is the largest wind-driven current on Earth and the only ocean current to travel all the way around the planet.
What is the fastest ocean current?
the Gulf Stream
Off the Atlantic seaboard of the United States, the Gulf Stream flows at a rate nearly 300 times faster than the typical flow of the Amazon River. The velocity of the current is fastest near the surface, with the maximum speed typically about 5.6 miles per hour (nine kilometers per hour).
How deep is the South Atlantic Current?
800-1000 m
At depths of 800-1000 m, the SAC is still recognizable as a current core. In the south-western Atlantic, the SAC has an average volume transport of about 30 Sv in the upper 1000 m with maximum transport values as high as 37 Sv (Stramma and Peterson, 1990).
What is the largest whirlpool in the world?

Which ocean is the deepest?
the Pacific Ocean
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources.
Which ocean current is the most important?
The Antarctic Circumpolar Current is the only ocean current to circle the planet and the largest wind-driven current on Earth. It’s also 30% more powerful than scientists realized.
