Abstract

NOAA oceanographers have placed an identification ‘tag’ on a huge cold water eddy that broke through the Gulf Stream from the North Atlantic and is headed south. This eddy, another in an apparent series of massive bodies of water that may affect Atlantic coast weather, is now about 300 miles due east of Savannah, Georgia, moving south at the rate of approximately two miles a day.

The new eddy is so huge that its total volume is estimated to equal the amount of water in the Gulf Stream flowing past Cape Hatteras, North Carolina, in about 10 days. The Gulf Stream's volume approximates that of 2000 Mississippi Rivers, with a flow of 100 billion tons of water per hour, 22 times as large as all the rivers of the earth.
