On thin ice

28.10.2013
The Arctic Science Partnership is in the high Arctic studying polynyas. A polynya is an ice-free site in an otherwise ice-covered area. This particular polynya studied is located outside the Young Sund fiord in North-East Greenland and is maintained by high winds blowing the newly formed sea ice away from the area. Not a place you would normally want to be. But for this small team of scientists studying ice and ocean processes this is heaven.

Stowaways threaten fisheries in the Arctic

23.10.2013
The increased sea temperature expected in 2100 will in itself mean that the potential number of species introduced with ships will increase more than sixfold in Svalbard. These are the findings of a new study with participation from Aarhus University. In consideration of the fact that the number of ships in the Arctic will also increase there is good reason to be on guard - including in Greenland.

Sea ice in the paleoclimate system: the challenge of reconstruction sea ice from proxies

23.10.2013
Centre for Past Climate Studies, Department of Geoscience, together with the Arctic Research Centre are editors of a volume about the subject in the international journal "Quaternary Science Reviews.

The tundra – a dark horse in planet Earth’s greenhouse gas budget

09.10.2013
There are huge amounts of organic carbon in the soil beneath the tundra that covers the northernmost woodless areas of the planet. New research findings from Aarhus University show that the tundra may become a source of CO2 as the climate becomes warmer.

Changes at the top of the world

08.10.2013
Aarhus University plays a central role in understanding the major environmental changes taking place in the Arctic. This forms part of the basis for the decision-making process for future developments of the societies of the Arctic.

Climategreenland - a new climate change website

03.10.2013
Climategreenland is the Government of Greenland’s website about climate change in Greenland. The site is intended to be a resource to help you find the people, the organisations or the information that you are looking for. It also provides an overview of some of the ways in which Greenland is affected by a changing climate and how this is dealt with.

PostDoc fellowship on climatic and oceanographic changes in the North Atlantic

03.10.2013
Call for applications: This call invites to a PostDoc fellowship for research on climatic and oceanographic changes in the North Atlantic, and their effects on plankton and fish. The fellowship will be lead by a steering group, appointed by the Faroe Marine Research Institute in Torshavn, Greenland Institute of Natural Resources, Nuuk, DTU‐Aqua and Aarhus University.

Climate change: Polar bears change to diet with higher contaminant loads

20.09.2013
Over the past 30 years, polar bears have increasingly exchanged ringed seal with harp seal and hooded seal in their diet. This change exposes the polar bear to more contaminants, according to a recent international study.

Micro-gels from tiny Arctic and Antarctic ice algae play an important role in polar ocean carbon budgets

12.09.2013
Secretion of polysaccharides from the micro community living within the sea ice stick organism together and forms greater particles introducing a rapid transport of carbon to the seafloor. New research now makes it possible to forecast the importance for the global carbon budget of this transport.

New book: The meaning of ice to the Inuit

04.09.2013
The book is the result of a interdisciplinary and international cooperation among young and old hunters and academics from various areas, such as anthropologists, geographers and glaciologists. The driving forces behind the book are, to name a few, Shari Fox Gearheard from Canada, Henry Huntington, USA, Lene Kielsen Holm and Toku Oshima, Greenland.
