Arctic Glacier Retreat Increases Iceberg Activity and Alters Deep-Sea Ecosystems

Research indicates a significant rise in Arctic iceberg numbers since the 2000s, primarily due to the destabilization of major glaciers in Greenland and the Russian Arctic. As these icebergs melt, they deposit debris and sediments, creating new hard-substrate habitats on the seafloor and gradually changing existing deep-sea communities. This phenomenon also presents growing hazards for shipping and fisheries in the region.
