Plants on the run: Can High Arctic species survive climate change?

10 November 2011

As temperature increases, High Arctic plants need to migrate to find new suitable habitats. Sexual reproduction and dispersal abilities will be critical survival factors. In his PhD thesis, Eike Müller concludes that these plants produce viable seeds and disperse well, thus their fate may not be extinction. Müller will defend his PhD thesis on 16 November at UNIS.

A long journey for terrestrial invertebrates

20 September 2011

Invertebrates play a very important role in Arctic ecosystems, but very little is known about their recent history. PhD candidate María Luisa Ávila Jiménez has studied the biogeographical factors in order to define the distribution of invertebrate species in the Arctic and Svalbard. Jiménez will defend her PhD thesis on 22 September at UNIS.

Arctic fjords: Challenging for weather prediction models

13 September 2011

Arctic fjords represent one of the most challenging environments in the world for weather prediction and climate models. PhD candidate Tiina Kilpeläinen has identified the main challenges for the weather prediction models. Kilpeläinen will defend her thesis on 15 September at UNIS.

Vorticity waves and heat loss in the ocean outside Svalbard

14 June 2011

Sigurd Henrik Teigen has investigated heat loss processes in the West Spitsbergen Current outside Svalbard. Through idealized calculation models he has investigated the importance of flow instability for the cooling of the current. His study contributes to the quantification of the processes that modify the warm core of the current before it reaches the ice covered Polar Ocean.

Geophysical investigations of Svalbard reservoirs

6 June 2011

PhD candidate Karoline Bælum has investigated subsurface reservoirs in certain areas of Spitsbergen, producing new knowledge about structures that one day can become important reservoirs for CO2 storage. Bælum will defend her PhD thesis on 10 June at UNIS.

New knowledge about life in the sea ice

28 April 2011

PhD candidate Henrik Nygård has studied the ecological traits and adaptations of benthic amphipods in the High Arctic. His findings also provide unprecedented insights into the life and ecology of related species living in ice infested waters. Nygård will defend his PhD thesis at UNIS on 2 May 2011.

Sea ice action on coastal infrastructures

8 December 2010

PhD candidate Fabrice Caline built a 50 meter long breakwater in Svea to study the action of sea ice on coastal infrastructures.

Caline will defend his PhD thesis on December 10 at UNIS.

Weather and climate 90 km above Svalbard

23 February 2010

Observations of airglow and meteors above Svalbard reveal important information about the weather- and climate changes in the upper part of the atmosphere, according to Margit Dyrland’s PhD research. Dyrland will defend her thesis at UNIS on Thursday February 25.

Dissertation on the Paulabreen glacier surge

11 December 2009

Lene Kristensen’s PhD work has been on the surging glacier Paulabreen in inner Van Mijen fjorden. Kristensen captured the progress of the surge on camera, and it is the first time image documentation of an ongoing glacier surge has been recorded. She will defend her PhD thesis on 14 December at UNIS.
