Huge Phytoplankton Bloom Found Under Arctic Ice

ananyo writes "Researchers have been shocked to find a record-breaking phytoplankton bloom hidden under Arctic ice. The finding is a big surprise — few scientists thought blooms of this size could grow in Arctic waters. The finding implies that the Arctic is much more productive than previously thought — researchers now think some 25% of the Arctic Ocean has conditions conducive to such blooms (abstract). The discovery also helps to explain why Arctic waters have proven such a good carbon dioxide sink."
