The Adélie penguin is an indicator species for changes studied by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to monitor changes in krill resources, ice and heavy metals, for example. Image: Coline Marciau / French Polar Institute...
Humpback whales migrate into the Southern Ocean every spring, attracted by the abundance of krill. The individual populations have clearly defined routes and feeding areas. This makes them ideal indicator species for pollutant monitoring in remote regions. Picture:...
The Greenland ice sheet has not been included in Arctic mercury budgets despite increasing annual meltwater discharge to the ocean and high mercury levels in Arctic organisms. The results of the current study are likely to change that. Photo: Dr. Michael Wenger...
The tusks of narwhal bulls are imposing tools with their length of up to 3 meters. For a long time it was not clear what they were for. Today we know that they are not only a dominance feature but also a sensory organ in the darkness of the Arctic Ocean. The teeth are...
The Arctic permafrost soils, here in the Yukon region of Alaska, contain twice as much mercury as all other soils, the oceans and the atmosphere combined. If it enters rivers as a result of thawing processes, the pollutant load on fish and other animals would...
