Animals at risk from increased Arctic Shipping

The polar bear may be the animal most often identified with climate change, but it is far from the only creature at risk from rising temperatures. The northernmost part of Earth is warming two to three times faster than the rest of the planet. This means the melting sea ice is opening new routes for shipping.

The melting ice has cleared space through the historically dangerous Northwest Passage, and the Northern Sea Route, along Russia's northern coast. This has sharply increased shipping in what was once a largely untouched ocean. Donna Hauser is a marine biologist with the University of Alaska Fairbanks. Hauser says she and other people expect more ships to sail in Arctic waters.

“Part of what motivated the study is to understand where we're at and where we need to go." Hauser says she was interested in studying the possible threat to Arctic marine mammals from shipping. Hauser says her hope was to protect both these animals and the people who depend on them.

"All of these species are really important traditional resources for indigenous communities throughout the Arctic as well as in Alaska and in the Alaskan Arctic, in particular." Hauser and other researchers looked at seven Arctic species: beluga whales, narwhals, bowhead whales, ringed seals, bearded seals, walruses, and polar bears. They created a risk measure that combined the general sensitivity of these animals and their contact with shipping.

The researchers limited their study to the month of September. This is when sea ice is at its lowest point and most ships pass through Arctic waters.
