The changing Arctic Ocean
After eventful and busy months, the Arctic season ends this weekend with the Polarstern expedition called ArcWatch-1. The team of almost 100 crew and scientists measured sea ice thickness and properties, recorded the currents and chemical properties of the ocean and investigated life in and under the ice, in the open water and at the bottom of the deep sea. Their data show significant changes compared to previous expeditions.

Polarstern reaches North Pole
Five weeks after setting sail from Tromsø, Norway, the Alfred Wegener Institute's research vessel Polarstern makes a stop at the northernmost point on Earth. Here, too, the international team of researchers is investigating the coupling between sea ice, the ocean and its life, including within the deep sea.
Microplastic contamination has reached the Arctic
Quantifying the amount of microplastic that appears on beaches and understanding where it came from is difficult. Scientists asked tourists on Arctic cruises to take part in a program of sample collection while visiting Svalbard and used these samples to identify microplastics that probably originated from ships and fishing net.
