The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. A new study shows how these changes can force wild reindeer to graze on seaweed, a strategy that increases their likelihood of survival— and is recorded in their poop.
When your airport runway is located at 72 degrees south latitude and more than 4000 kilometres from the nearest major city, it better be in tiptop shape. But in Antarctica, where most runways are made of snow or ice, holes can be a big problem.
We know that tiny marine creatures in the Arctic respond to weak light from the Moon or the northern lights during the polar night. Now researchers have learned that artificial light from research vessels can also have a negative effect.
Help is not just a phone call away if you have an accident in the Arctic. That’s why the far northern Norwegian archipelago of Svalbard is establishing an educational and research centre for Arctic safety.
You might think that polar bears— and the potential for attack— are the biggest danger on the Norwegian island archipelago of Svalbard. But avalanches kill far more people on Svalbard than polar bears ever have.
Global climate change is causing Arctic sea ice to melt at an accelerating rate, increasing the ability of ships and other structures to travel though Arctic waters. But even as they melt, some sea ice structures actually get stronger.
Global warming means much warmer winters in the Arctic, with more rain and icing. Researchers are working to understand what that will do to plants that have evolved to overwinter under a thick blanket of snow.
The polar night descends on the arctic archipelago of Svalbard for more than 100 days a year. But even in the depths of this darkness, the oceans are churning with activity.
Every year, an estimated 8 million metric tons of plastic waste blows, falls or flows into the world’s oceans. Earlier this autumn, participants in the annual Svalbard Course plucked up 512 kg of the stuff from just one beach in two hours.
