The role of light in the polar night

24 September 2013

Anna Solvang Båtnes has studied the role of light in the Arctic marine ecosystem during the polar night, a time of year when it appears completely dark to the human eye. Båtnes performed parts of her fieldwork at UNIS and will defend her PhD thesis in Trondheim on Thursday 26 September.

Reveals more of Svalbard’s glacial history

6 March 2013

Endre Før Gjermundsen’s doctoral research shows that the ice cover over Svalbard during the last ice age started melting far earlier and the melt period lasted longer than previously assumed. Gjermundsen will defend his PhD thesis on 8 March in Oslo.

Snow avalanches in Central Svalbard

12 January 2013

PhD candidate Markus Eckerstorfer has conducted frequent snow avalanche field-based monitoring in the Longyearbyen area to identify most common avalanche types and snow climate. His study will contribute to the establishment of observation routines and computer models for future warning. Eckerstorfer will defend his PhD thesis on 16 January at UNIS.

Increased knowledge about sea ice

18 May 2012

Sea ice is the main challenge to the development of oil and gas industries and the exploitation of these resources in the High Arctic. Ships and safe structures should be designed by taking into account sea ice concentration, thickness and strength. Lucie Strub-Klein has studied level ice and sea ice ridges and will defend her PhD thesis on 22 May at UNIS.

New knowledge about surging glaciers

13 December 2011

New research by PhD candidate Monica Sund show that the dynamics of both surge- and tidewater glaciers must be taken into consideration when assessing the glaciers’ response to climate change. Sund will defend her PhD on 15 December at the University of Oslo.

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.
