Narwhals Mapped Warm Water Invading Greenland's Most Remote Glacier Inlets
Often nicknamed the unicorns of the sea, these tusked whales spend much of their lives diving deep into the icy waters off East Greenland's coast, a habit that made them accidental oceanographers.

Climate change is taking its toll in Greenland. The warm waters of the Atlantic are penetrating into the eastern fjords and melting the base of glaciers miles inland. A team of scientists installed special sensors in several narvals for data measurement. Thanks to these animals that can reach 1500 meters deep, it was possible to prove that the warming of the waters is out of control. This atlantification poses a very serious threat not only beca…
Narwale with measuring instruments have supplied data from more than 1500 meters depth. They show how far warm Atlantic water is now penetrating – up to the glaciersNarwale swim to where research vessels reach their limits: deep into the remote fjords of East Greenland, under sea ice and in waters, cold to near freezing point. The Arctic marine mammals also dive in winter, thus reaching the most remote corners of the icy waters.
Measuring aid with tusk: Six narwals have recorded temperature and salinity in East Greenland's scoreby-sund system up to more than 1,500 meters depth. Together with historical measuring series, their data show that warm, salt-rich Atlantic water penetrates far into the fjords and reaches deep glacier basins there. This could further promote ice loss on the affected glacier fronts. Investigation area. Red dots mark narwal measurements from 2017 …
