Results of a Warming Ocean: Algae and Iron to Counter CO-2
by John Bowermeister
A group of scientists from the Alfred Wegener Institute for Polar and Marine Research in Germany is purposely trying to grow algae as a way to help absorb the increasing amount of warming CO2 found in the ocean. In a recent experiment, the group sprinkled iron into a patch of the Southern Ocean to essentially fertilize algae growth, which may—or may not!—soak up huge amounts of carbon. The idea is that the algae will suck up CO2 and then sink to the cold and dark of the ocean floor. If successful and practiced on a huge, international scale, enriching the ocean with iron could help slow the impact of global warming on the ocean. The worst case, though, according to the Natural Resources Defense Council, is that mucking up the ocean with a bunch of added iron could have serious impact on already-out-of-whack ecosystems.
