Ocean surface currents Distinctive white lines trace the flow of surface currents around the world. Visualization showing global ocean currents from January 1, 2010, to December 31, 2012, at sea level, then at 2,000 m (6,600 ft) below sea level Animation of circulation around ice shelves of Antarctica
The cooler ocean current along the west coast also makes summer temperatures cooler on the west coast compared to the east coast. For example, Half Moon Bay at 37°N has no month with an average high above 67 °F (19 °C) and San Francisco often stays below 70 °F (21 °C) in summer, while Virginia Beach, VA , close to the same latitude, has ...
The two currents don’t change directions, but they shift their paths on occasion, forecasters said. The Gulf Stream is also known to speed up and slow down. Impacts on the N.C. coast can include ...
A drifter (not to be confused with a float) is an oceanographic device floating on the surface to investigate ocean currents by tracking location. They can also measure other parameters like sea surface temperature , salinity , barometric pressure , and wave height. [ 1 ]

The Antilles Current is a highly variable surface ocean current of warm water that flows northwesterly, past the island chain that separates the Caribbean Sea and the Atlantic Ocean. The current results from the flow of the Atlantic North Equatorial Current. This current completes the clockwise- cycle or convection (North Atlantic Gyre) that is ...
The South Atlantic Current is an eastward ocean current, fed by the Brazil Current. That fraction of it which reaches the African coast feeds the Benguela Current . It is continuous with the northern edge of the Antarctic Circumpolar Current .
It is 250 miles (220 nmi; 400 km) wide and flows to the east. It is hidden 300 feet (91 m) under the surface of the Pacific Ocean at the equator and is relatively shallow compared to other ocean currents being only 100 feet (30 m) from top to base. It is a powerful current with top velocities of up to 1.5 m/s (2.9 knots; 3.4 mph).
