Ecological consequences for Arctic species communities
Arctic environments are characterised by a harsh climate, low human population densities and by hosting relatively simple ecosystems. Alterations of Arctic ecosystems may have ...
Qullissat: New paths to the future by building on the legacies of the past
... unemployment, abandoned infrastructures and production facilities, and radically altered landscapes. Therefore, debates on possible post-industrial futures have attained a great importance. The field work is part of the project ...
Investigation of exposure to whole body vibration for icebreaker crew
Few investigations have been conducted regarding exposure to whole body vibration (WBV) for ice breaker crews. Previous studies have ...
Trace carbon dioxide and methane along the coast of Greenland
The flux of the greenhouse gases carbon dioxide and methane from shallow sea sources to the atmosphere is thought to be an important part of the global carbon cycle. By making continuous measurements of carbon ...
History of the Petermann Glacier
... north-western sector of the Greenland Ice Sheet into the Petermann Fjord. It is an active glacier with an ice stream that extends into the fjord as a floating ice tongue, also known as an ice shelf. The ice tongue appears to be thinning and ...

Radar for measuring sea ice thickness
Radar antennas on board Oden. The icebreaker Frey is visible in the background. Photo: Per Holmlund Vessels that sail in ice-covered areas disturb the sea ice and trigger a number of processes. The vessel may break the ice sheet into ...
How are marine microalgae on King George Island affected by climate change?
Francesca Pasotti from Ghent University prepares to dive into the ice-cold water. Photo: Anders Torstensson Climate change is occurring faster in Western Antarctica than in many other places on ...
The effects of Arctic sea ice on floating structures
All participants on icebreaker Oden. Photo: Per Frejvall The OATRC 2015 expedition was carried out between 18 September and 2 October as a two-ship operation in the Arctic Ocean north ...
Navigating in sea ice with the help of satellite images
... Hanna Hagelin The ice has a major bearing on how vessels in both the Bay of Bothnia and the Arctic choose to navigate during the season when the sea is covered by ice. Choosing to sail in areas of open water or thin ice makes it possible ...

Searching for Ichthyostega bone fragments near the summit of Celsius Bjerg. Photo: Benjamin Kear Vertebrates first emerged onto land during the Devonian 358 million years ago. 108 million years later in the earliest Triassic, ...
Unique measurements from the North Pole show how the sea ice, the atmosphere and the biosphere interact with each other
... and from primary production in the oceans, i.e. when plants, algae, and cyanobacteria convert carbon dioxide and water to organic substances with the help of photosynthesis. Parts of this organic carbon can then be broken down and ...
What impact does climate change have on the distribution of mercury and plastic microparticles in the Arctic?
Each year, several tonnes of mercury end up in the Arctic Ocean. This mercury is transported from more southerly latitudes with the help of the wind and originate from, for example, the burning of fossil fuels and small-scale gold ...
Early Career Scientists Programme 2016
In conjunction with the Swedish-Canadian research expedition Arctic Ocean 2016, the Swedish Polar Research Secretariat invited researchers in the early stages of their careers to participate in the expedition under the auspices of the ...
Who has the rights to the seabed resources in the Arctic Ocean?
... icebreaker Oden in the Arctic Ocean. Photo: Åsa Lindgren The appearance and structure of the seabed can reveal a great deal about the history of our planet. It is the movement of the continental plates that has shaped the polar regions as ...
Knowledge of how clouds are formed in the Arctic helps us to predict future climate
The climate in the Arctic is particularly sensitive, and the Arctic average temperature increases more quickly than that in the ...
Rocks provides an important indication of the impact of climate change on the Antarctic ice sheet
The MAGIC-DML team. Photo: Carl Lundberg Almost all of Antarctica is covered by ice. Underneath the ice sheet is a landscape composed of hills, valleys, mountains, and planes, similar to landscapes on other ...
Measuring the changes in the ocean’s capacity to absorb carbon dioxide
More than one quarter of the CO2 in the atmosphere is absorbed by the oceans. The Southern Ocean accounts for around 40 %, but according to some models, the ...
How are the living conditions of the Arctic Cod affected by decreasing sea ice?
