Scientists have equipped narwhals with satellite transmitters to collect data on the ocean. These marine mammals, known for their long, spiral tusks, were tracked for three years. The information gathered is concerning and provides further evidence about the state of the ocean.

The narwhals were followed as they swam through a complex system of fiords and along a rugged coastline. Their movements were monitored to gather data on this remote region.

Further details about the findings and the research are available, but it is known that the data collected is alarming, particularly regarding the Arctic.
