Coral reefs coming back from the dead

Posted April 08, 2008 8:30 AM

From Boing Boing:

Perceptive Travel reports that efforts to re-seed dying coral reefs are performing better than anyone dared hope. This is the best news I've had this season -- I've been convinced that the reefs would all be dead before my daughter was old enough to dive them. On land, EcoReefs look attractive but artificial, like contemporary sculpture. Nearly two years later, they're something else entirely: a hybrid of technology and organic life, like Jeff Goldblum at the end of The Fly. Their antler-shaped arms are covered with baby corals and sponges, more varieties than I can count. Parrotfish, Moorish idols and clownfish have set up shop beneath their limbs; two tiger cowries nestle near one's center.

GOOD NEWS,

just made a trip to RED SEA, EGYPT, to pass diver certification test, some of my

co-divers were grounded for touching coral reef inententionally being told damages were almost definitive...

Will forward info to Dahab divemasters,

Thanks Boing Boing,

last July I went to Bon Aire to dive with my buddy for a week. It was truly awesome week and I made 20 dives in about 6 days. Bon Aire is set up for shore diving and has some of the best reefs I have ever dove upon. Bon Aire is also very aggressive in perserving their reefs and they have rules such as no gloves allowed, do not touch the reefs, no suntan lotion etc. Although I did see and occasional bleached or dead coral for the most part these reefs are in very good condition. I think we all as divers need to follow these rules wherever we dive. Just look at the stuff and keep your hands off. Work on being able to balance your weight so you don't accidentally sink down and touch the reef. These little things will help the reef survive and are things we can do very easy. I have also dove on allot of artificial (man-made) reefs around the coast of Florida. It is amazing how fast the corals and sponges and fish start accumulating around the old sunken ship or other structures. The one thing they don't like though is old tires. i recently read where they were removing 1000's of old tires from the ocean bottom after a failed attempt to make a reef from them. Anyone know why the tires don't work?

"Anyone know why the tires don't work?"

Not definitively, but I suspect some chemical component, similar to a plasticizer, deters them from attaching, or even may kill the young sponges and coral polyps. Haven't heard of research done in this area, but I'm fairly certain something is at least underway and ongoing, if not complete.

My understanding is the problem with the tire reef you mention is the lashings that held them together broke so the tires would break apart and move around thereby destroying the very marine life they were suppose to harbor and protect.
