Narwhals, known for their long tusks, which are actually teeth, have been chosen to help scientists research global warming.
Since these whales make very deep dives, scientists have attached sensors to them to record ocean depths and temperatures.
Narwhals continue to feed and swim even in the harsh winter weather. This is the time when scientists have not been able to do much research due to the chill.
These scientists were able to fill in a few gaps in their data. Thanks to the whales, they found out that on average their ocean temperature measurements were almost a full degree greater than those in climatology data.
These specific Narwhals in Baffin Bay, near West Greenland, were chosen due to the conditions of Baffin Bay. It is right next to Greenland where slabs of ice are breaking off and sliding into the ocean.
Thanks for your help whales!!
