Saving Hawaii corals-so cool.

I watched a "Modern Marvals" show on vaccums tonight. One segment was on what they called "The Supervac". They go out on a barge with this thing with marine biologists and several workers to save their reefs. Instead of hand picking off "foreign" algae, they now vaccum it off, so the corals can get sunlight and survive. First, 4 divers go down with big hoses, pick the algae off, then let it get sucked up instead of having to bring it to the surface bag by bag. Then, the algae above deck goes onto a screen where workers separate any sea life, and the divers return the sea life back to the reef. As much as 800Lbs of algae is gathered in 3 hours. The algae is then used for fertilizer for organic foods. I have heard of dead zones in the ocean, but cleaning it up was new to me! Maybe there's hope after all!

 

I guess I should have put this in the environmental section! OOps!

 

Thats pretty cool, but I dont think they are doing that to dead zones. Dead zones are usually where river delta's and the like come out. Such as the Mississippi river delta, Cheasapeake Bay water shed and several places along the coast of California and Mexico. Whats doing the most damage is fertilizers from farmers and what people put on their lawns. These deads have actually not increased like scientists have thought they would, they've actually got better the past year or two.
