Recent temperature readings collected with the help of sea mammals has revealed that the water in Baffin Bay, which links the Arctic Sea to the Atlantic Ocean, is getting warmer. In the study, US scientists led by Dr. Kristin Laidre of the Polar Science Center at Washington University placed a small device with temperature sensing data and satellite transmitter upon narwhals, a native marine mammal with a unicorn-type horn.
The oceanographic instruments measured sea temperatures throughout the winter in Baffin Bay, an area oceanographers had not previously been able to measure. In this study, the researchers found that the isotherm, a layer of winter surface water that normally protects the surface sea ice from higher temperatures below, was 50 to 80 meters thinner than climate models predicted.
This in turn allows the warmer water to mix more with the colder water, speeding the rate of surface ice melting. The researchers also found the water to be about 1 degree Celsius warmer than their previous estimates.
We are grateful, Dr. Laidre and colleagues, for your careful work and observations. Knowing of these threats to the Arctic and their potentially devastating consequences, let us rapidly act to halt climate change.
