Hans Christensen: Quadruple Number of Icebergs Risky for Ships

A huge increase in the number of drifting icebergs is a major concern for ships around Greenland. Rising temperature leads to release of more icebergs that drift south along the coast.

The number of icebergs in the Arctic has quadrupled since the early 2000s. A recent study, published in Nature by researchers including some from the Technical University of Denmark DTU Space, reports that the melting of major glaciers in Northeast Greenland and the Russian Arctic is resulting in a greater number of icebergs entering the ocean. Glaciers are calving many more icebergs into the ocean. They then move with the prevailing ocean currents, generally southbound towards the Atlantic. Drifting icebergs pose increasing risk to shipping around Greenland, calling for intensified monitoring and alertness, say the researchers.

Icebergs can carry a surprising quantity of rocks and sediments from land and move them several hundred kilometers into the ocean. When the icebergs melt, the stones sink to the seabed, affecting life nearly 2,500 meters beneath the ocean’s surface. The solid surfaces on a generally soft seabed provide a foundation for sponges, sea anemones, and various other organisms to thrive.
