 enclosing colder northern water within them are identical 

 with the so-called cold pools first described by those aboard 

 the Eliza in 1810 and wrongly attributed to the melting of 

 icebergs trapped within the Stream.

 and the southernmost streams seem to die away to the east. 

 The exact nature of this triple stream is unknown, but it is 

 at least certain that the Gulf Stream does not divide in the 

 way a tree branches. Another puzzling discovery of Operation 

 Cabot was that the warm water flows in pulses. And so — as 

 always — in attempting to answer its own questions science 

 has found new problems to solve.
