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’.

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.
