(PhysOrg.com) -- A team of marine scientists has found that toxin-producing algae once thought to be limited to coastal waters are also common in the open ocean, where the addition of iron from natural or artificial sources can stimulate rapid growth of the harmful algae. The new findings, reported this week in the Proceedings of the National Academy of Sciences, add to concerns about proposals to use iron fertilization of the oceans as a way to combat global warming.
