Hurricane Dolly may have shrunk Gulf 'dead zone'

July 29, 2008 By JANET McCONNAUGHEY , Associated Press Writer

(AP) -- The oxygen-starved "dead zone" that forms every summer in the Gulf of Mexico is a bit smaller than predicted this year because Hurricane Dolly stirred up the water, a scientist reported Monday.

  The process causing the dead zone is also sequestering carbon in CO2.

  Is there any biologist or oceanographer who would answer a speculative question? If Dolly can "stir up" the dead zone, what are the prospects of doing this artificially? Say, by floating machines using wind/sun/ocean waves as an energy source?

  Does not fit "the template", I can't believe it is up here. I guess a token to objectivity... Cute.

  Floating, wave-powered pumps, designed for this very purpose, are now undergoing proof-of-concept testing.
