A Way to Trap Carbon Deep in the Ocean
After an eight-year analysis, an international team of scientists has announced a breakthrough in the understanding of how algae and iron interact to sequester atmospheric carbon.
By adding iron to the ocean, the researchers induced a massive algal bloom. A significant portion died and sank to the ocean floor, carrying its sequestered carbon along with it to the depths. The finding contributes to scienceâ€™s understanding of the global carbon cycle and has implications for potential ways of mitigating rising levels of carbon dioxide, which contributes to climate change.
