EAST AUSTRALIAN CURRENT

surface oceanic current, a section of the counterclockwise flow in the Tasman Sea, southwestern Pacific Ocean. It is formed by water masses from the Coral Seaequatorial water driven by monsoonal winds from January to March and eastward subtropical flow from April to Decemberwhich pass southeast between the Great Barrier and Chesterfield reefs (20 S latitude), paralleling the east coast of Australia into the Tasman Sea. Narrowing as it approaches 25 S latitude, the current is strongest off Cape Byron, New South Wales. It weakens and begins to dissipate beyond 32 S latitude, but its remnants continue to drift southward until, off Tasmania, they swing eastward and begin to flow north as the Tasman Current. At the surface its salinity is more than 35 parts per thousand, increasing to a maximum of 35.8 at a depth of 660 feet (200 m). Reaching depths greater than 3,300 feet (1,000 m), the East Australian Current transports about 1,100,000,000 cubic feet (30,000,000 cubic m) of water per second.
