This summer, a Swedish oceanography team will participate in the PS106 expedition on board the German research vessel Polarstern in the Arctic Ocean.
Movie: Mercury in the Arctic17 May 2017
Each year several tonnes of mercury end up in the Arctic Ocean. This mercury is transported from more southerly latitudes with the wind. In the Arctic it is converted into methyl mercury.
Petermann is the canary in the coal mine for how the world changes16 February 2017 | Saskia Madlener
The Petermann 2015 expedition is a perfect example of how we study iconic systems. Whats interesting with this place is that it has an floating ice shelf that protects the glacier that extends deep into Greenland's interior, some sort of the drain of Greenland.
Med SWERUS-C3 till Arktis26 October 2016
Stockholms universitet har producerat en film om den internationella forskningsexpeditionen SWERUS-C3 med isbrytaren Oden i Arktiska oceanen.
On the hunt for 370 million year old fossil29 September 2016
The first of these adaptive radiations ocurred 370 million years ago, when the earliest tetrapods modified their fins into legs and emerged onto dry land. By 250 million years ago this process had reversed, and the tetrapod walking limb was once again remodeled into a fin for a return to life in the sea. But what was it that drove vertebrates to leave the water 370 million years ago? And why did some reptiles return to the water 150 million years later?
Back in Longyearbyen20 September 2016 | Åsa Lindgren
Back in Longyearbyen after six weeks. We ended the expedition with some rough waters from the ice edge down to Longyearbyen.
Why do the scientists send balloons up in the air?16 September 2016
Atmosphere scientists on board icebreaker Oden uses weather balloons to make measurements in the air. The measurements can be used for e.g. making weather forecasts.
På väg söderut16 September 2016 | Åsa Lindgren
Nu är vi på väg söderut genom isen ner mot Svalbard och i takt med att vi närmar oss iskanten blir det alltmer liv omkring oss.
Meteorologist Nicke shows what the researchers do on board the icebreaker Oden13 September 2016
Nicke Juuso work as the expedition meteorologist during the expedition Arctic Ocean 2016. In this video he shows what the scientists are doing on board the icebreaker Oden and why they have gone all the way up to the Arctic Ocean.
Can we break the ice?13 September 2016 | Martin Heyn
Ice is a complicated and very fascinating material. If you freeze water at home in a freezer, you get a very solid ice cube, that is wonderful to use in a cold drink. This is already the first surprising property of ice; it swims on top of water.
This is how researchers reveal the history of the Arctic12 September 2016
The sediment on the sea floor is like an archive, it reveals past environmental conditions in the the Arctic history. The researcher Grace Shephard is now on board icebreaker Oden on the Arctic Ocean 2016 expedition, and she explains how they collect samples of sediment to be able to see what the Arctic conditions was millions of years ago and how it has changed until today.
Sun dog physics10 September 2016 | Ian Brooks
Summer in the central Arctic Ocean is usually overcast and grey, with low cloud or fog being present for more than 90 % of the time. Occasionally, however, the sun does come out, and when it does it can sometimes be spectacular.
Ett pussel med oändligt många bitar8 September 2016 | Åsa Lindgren
Planeringen av en polarexpedition är lite som att lägga ett pussel med oändligt många bitar. En del bitar är stora och påtagligt dominanta, men ofta hänger en lyckad expedition på att man även lyckas få med de små bitarna in i helheten.
Measuring aerosol particles3 September 2016 | Piotr Kupiszewski
Part of the meteorological work package on board Oden involves measuring the properties of aerosols, i.e. tiny particles suspended in the air. Aerosols are very important for the climate because they act as nuclei on which cloud droplets and ice crystals form.
Visiting Louis S. St-Laurent2 September 2016 | Robert Holden
The ship which was deserted earlier this morning was now more alive, and people were milling around with a little excitement or expectation showing on their faces. Apparently we may have the chance to get aboard the Louis.
Film: Det här gör meteorologen på en forskningsexpedition29 August 2016
Meteorologen Nicke Juuso berättar vad han gör på isbrytaren Oden under Arctic Ocean 2016.
Seismic lines27 August 2016 | Åsa Lindgren
The last couple of days, we have been busy with seismic lines. This means that Oden is breaking ice in straight lines through heavy, massive ice with ridges while the Canadian icebreaker Louis S. St-Laurent is following and shooting off seismic signals.
Radiosonde hacking23 August 2016 | Lars Lehnert
As part of our research programme during the Arctic Ocean 2016 expedition we were planning to launch meteorological radiosondes every six hours, with the data being used both for research and sent to the EUMETNET service for use in initialising forecast models. Unfortunately, the receiver of the sounding system failed at the beginning of our expedition.
We reached the North Pole!22 August 2016 | Åsa Lindgren
Everyone on board, 67 persons, gathered on the bridge to celebrate when the GPS came closer and closer to the latitude 90°N.
The last day together in the field20 August 2016 | Lasse Tano
Today was probably the last day together in the field for the four of us. There may be some work tomorrow too, but the priority is to go through and sort/tag all fossils.
