Fremtidens arktiske specialister bliver klædt bedre på

Klimaændringer og nye økonomiske muligheder stiller store krav til rådgivning og forvaltning i det arktiske område. Nu går Grønlands Universitet, Færøernes Universitet og samtlige danske universiteter sammen om at ruste nye kandidater til opgaverne ved at uddanne arktiske specialister på tværs af mange fagområder.

Arctic collaboration is strengthened

The stage is set for a significant strengthening of Danish efforts in Arctic research and education following the two-day conference held at Hindsgavl Manor in Middelfart, which was attended by eighty researchers and representatives from authorities in Denmark, Greenland and the Faroe Islands. The aim was to kickstart the Arctic Initiative, which…

Since 2009, whalers along the east coast of Greenland have caught killer whales whose presence has increased in the sea along the coast. Particularly in the Tasiilaq area, killer whale serves as food for both humans and sledge dogs. Photo: Haukur Sigurdsson.
A female killer whale weighing about six tons caught outside Kulusuk in August 2013. The whale had fed on seals and baleen whale, and samples were taken of tissue and milk from the mammary glands.

In August 2014, the local population of Tasiilaq, East Greenland, was interviewed about their life style and diet habits. Blood samples were taken from individuals eating killer whale meat. Photo: Rune Dietz, Aarhus University.

Killer whales on the Greenland menu – a cause of concern

More and more killer whales search for food along the Greenland east coast, and the local inhabitants now hunt whales that serve both as food for their families and as dog food. Researchers believe, however, that killer whales can have the highest concentrations of pollutants in the Arctic area.

Workshop kickstarts new Arctic initiative

At the end of September, researchers from institutions in Denmark, the Faroe Islands and Greenland will meet with authorities connected with the Arctic region. The meeting is the start of joint Danish efforts in Arctic research and education initiated by the University of Copenhagen and Aarhus University.

Polarsekretariatet

Forholdene omkring Arktis har i de senere år tiltrukket megen opmærksomhed, blandt andet i forhold til klimaforandringer, potentielle råstoffer, nye sejlruter mv. Polarsekretariatet skal være med til at skabe bedre overblik over polarforskningsaktiviteterne

Miljøgift gør orme kuldskære

Nogle miljøgifte er mere skadelige i et koldt klima end i et varmt, fordi de påvirker temperaturfølsomheden hos visse organismer. Nu har forskere fra tre danske universiteter sammen påvist hvordan. Det kan give mere præcise risikovurderinger af forurening, navnlig i Arktis.

Tomme reder i Nordatlanten

Havfugle kolonierne i Nordatlanten skrumper. I løbet af de sidste 10 år er ynglesuccesen for bl.a. Lunden og den Arktiske Terne faldet drastisk, og det er især tydeligt på Island, der ellers plejer at være havfuglenes Serengeti.

Film om uddannelser og forskning i Arktis

AlphaFilm besøger i disse dage Naturinstituttet i Nuuk for at lave en række korte film, der fortæller om de mange muligheder, man som ung har for uddannelse og forskning i Grønland og ikke mindst ved Naturinstituttet.

To catch small animals, the scientists use so-called Malaise traps named after the biologist René Malaise who made the first model. Here, biologist Mikko Tiusanen checks one of the traps. The insects are caught by the tent walls and led to a container with alcohol. Photo: Peter Bondo Christensen.
Many different types of traps have been used to obtain a general idea of the Zackenberg fauna. Here, biologist Riikka Kaartinen from Helsinki University uses yellow pan traps to catch flies and wasps. Photo: Tomas Roslin.
Different kinds of small nets and artificial sticky flowers are also used to catch insects at the arctic tundra. Photo: Peter Bondo Christensen.

Udslip af metangas er en uhyggelig joker i den globale opvarmning

Sommeren går på held på vore breddegrader og igen i år er der sat varmerekorder mange steder. Også i de arktiske områder. Temperaturen på den sibiriske tundra har f. eks været usædvanligt høj. Faktisk har de to seneste somre været hele fem grader varmere end gennemsnittet. Det har fået det til at boble med opsigtsvækkende og ret uhyggelige…

In the sea outside the research station Daneborg at the fjord Young Sound, a large ‘ice factory’ is found. Here, the sea water freezes to ice. But time and time again heavy winds blow the ice away and expose the sea, allowing yet more sea ice to be formed. Such an area is called a polynya. Polynya is Russian for ’pool’. Photo: Peter Bondo Christensen
Gases – including carbon dioxide - are squeezed out when the ice is formed and dissolve in the highly salty water that flows from the ice. This means that when the ice melts in spring, the water is highly undersaturated with carbon dioxide. The sea will therefore absorb large quantities of carbon dioxide, and the formation of sea ice consequently acts as an important carbon pump. The photo shows Nicolas-Xavier Geilfus, Arctic Research Centre, Aarhus University, and Karrie Warner, University of Manitoba, measuring the absorption of carbon dioxide by meltwater pools on top of the sea ice.

Siiri Wickström, University of Helsinki, and Tim Papakyriakou, University of Manitoba, have set up a monitoring station on the sea ice, allowing them to measure the amount of carbon dioxide absorbed and released by the sea ice. Photo: Peter Bondo Christensen
Every 10 km along the 100 km long fjord the scientists drill a hole in the ice and lower a so-called CTD-probe down the water column to the bottom of the sea. The probe measures temperature, salinity and a number of different salts and calculates the amount of carbon transported towards the sea bottom. Here, Søren Rysgaard, Arctic Research Centre, Aarhus University, and Sergev Kirillov and David Babb from University of Manitoba, Center for Earth Observation Sciences, Canada, lower the probe down through the sea ice.

The only means of transport in the melting sea ice is by snowboat or iceboat that can sail in water and drive on the ice. Carl Isaksen from the Greenland Institute of Natural Resources is a true master in handling the iceboat.  Photo: Peter Bondo Christensen

Summer at the sea ice factory

Far up north in the arctic ice 100 scientists and students are involved in a joint field investigation into how the interactions between snow, ice, sea and atmosphere in the Arctic impact the climate of the Earth.
