A new study reveals that the Svalbard reindeer turn to alternative food sources in tough winters, when the tundra get glazed over by ice. New research shows that the reindeer find alternative food along the shoreline, in form of kelp and seaweed.

Due to all the ongoing and predicted climate changes it is obvious that primary productivity in the Arctic is going to change – but still, there is very little reliable information available on the subject. PhD candidate Ane Cecilie Kvernvik has studied single-celled sea ice algae in Svalbard.

When Captain Albertsen from Tromsø slowly sailed into Rijpfjorden on 3 September 1945 to pick up the last of armed German soldiers in Europe, he had no idea of what was expecting him. Perhaps the fjord was full of fissured and half-melted drift ice as he headed south to the inner part of Rijpfjorden. That was the sight I met the first time I was in Rijpfjorden in September 2004. At that time I did not know how important Rijpfjorden would turn out to be for me, both as a researcher and as an individual.

Sea ice and snow reflect and absorb effectively up to 99% of all light, which in turn helps regulate the start and length of the algal bloom in the ocean below. This usually results in short and intense blooms when the sea ice melts. Arctic species show adaptations to such a production regime, usually because they are able to eat and put on a lot of weight in the short periods where there is food access, and then live on stored fat in meager times. But what’s that got to do with the kibble used for coal transportation in Longyearbyen in the past?

Fortunately, it is no bigger than 5–6 cm; otherwise it would have been a really scary sight. It is found mostly throughout the whole Arctic, and is a species we count as an indicator of cold water masses. And for all the smaller organisms, such as Calanus finmarchicus and Calanus glacialis, it is a ferocious monster!
