Melting icebergs seed rocky oases on the Arctic seabed

A Nature study shows rocks carried by Greenland and Russian glaciers and later dropped by melting icebergs settle on the Arctic seafloor, creating new habitats for corals, sponges and other deep-sea life as ‘dropstones’; warming climate accelerates glacier flow and iceberg melt, increasing rock delivery and fostering biodiversity hotspots in areas like Fram Strait since 2000.
