Scientists Cryo-Freeze Coral Reef

An anonymous reader writes "Due to rising ocean temperatures, scientists from the United States and Australia are attempting to freeze coral eggs and sperm in cryogenic suspension so that the endangered species can be preserved. Once frozen, the species may later be grown in a lab and implanted in reefs. This could be the only way to ensure the survival of certain endangered species at The Great Barrier Reef."

    Ocean acidification, although a daunting problem, isn't irreversible. The idea of saving just coral sperm and eggs doesn't sound like a well thought out solution, though. A coral reef is more than just bare coral. It is a matrix upon which an entire ecosystem is based. Does't the rest of habitat need saving as well? Imagine saving a place on land from soil erosion, but the hill or valley is completely barren with no plant or animal diversity.

    Coral given ideal (artificial) growth conditions such as those in Marine Aquarists' tanks can actually grow fairly rapidly.

    In the Marine Aquarist Community both Soft (LPS) and Hard (SPS) coral is usually traded as "frags" (fragments or cuttings off a mother colony,) and they can
    more than quadruple in size over the course of a year given ideal flow, nutrient, light and water chemistry conditions.

    What happened to natural selection? The planet constantly changes, and species die all the time, if ocean temperatures are going to kill them off how do they expect them to survive in a warmer ocean!!

     
    I've wondered this too. The seas tend to change by a foot or more every 200 years, with evidence of massive water level drops happening several times in the past. Either Coral is more resilient than we give it credit for, or this wide variety of coral appeared in just a few hundred years since the last major temperature/water level swing. Either way, there's definitely a major clue missing here. Huge chunks of Florida (Miami in particular) sit on top of ancient coral reefs. I mean, check out Coral Gables' Venetian Pool - where did all this coral come from? What happened to those species? That part of Florida no longer has reefs, nor has it had them for hundreds if not thousands of years. I think the Biologists and the Geologists need to get together and decide what's actually going on.

    Here is a cool trick, in the Summer take a hand full of M&M's, dive to the bottom of a pool and take a look. If you have more than about 4 feet of water over you you will not be able to tell the red from the blue. Red wavelengths of light are generally filtered out after a meter or so of water. The deeper you go the more color gets lost.
