Retreating glaciers increase iceberg sightings and reshape deep-sea habitats‎

The number of icebergs in the Arctic has increased sharply since the 2000s. This is due to the destabilization of large glaciers in northeast Greenland and parts of the Russian Arctic, as well as the increasing mobility of sea ice. The result: Stones rain down from the melting icebergs, forming new hard-substrate habitats for marine life on the soft seafloor.
