Measuring Ocean Acidity

During the 2010 and 2011 Catlin Arctic Surveys, it was  found that tiny sea creatures called copepods which live under the arctic ice will struggle to survive if ocean acidity continues to rise. This would be disastrous because these small creatures are essential to the arctic food web, meaning other creatures rely on feeding on […]

WWF Arctic

What do you think of when you imagine the Arctic? The first image that comes to mind is probably ice and snow – but this is only part of the picture. The Arctic is a vast area of fjords and tundra, jagged peaks and frozen seas, glaciers and icebergs, and ice and snow.

It’s the realm of the polar bear and ringed seal, caribou and arctic fox, beluga whale and narwhal, sea eagle and snowy owl. Visit WWF Arctic to learn more about this fragile environment.
