Solving the mystery of surging glaciers

12 October 2015

PhD candidate Heïdi Sevestre has investigated the global distribution of surge-type glaciers and uncovered differences in geometry between normal and surge-type glaciers. Her research has helped solve one of the biggest enigmas in glaciology. Sevestre will defend her PhD thesis at UNIS on 13 October 2015.

Warm Atlantic water drives the climate in the Arctic

21 August 2015

During the last 132,000 years, the Arctic climate varied significantly and this was closely related to the strength and variability in the inflow of Atlantic Water to the Arctic. This emphasizes the importance of considering regional environmental parameters and feedback mechanisms in reconstructions of the past climate, according to a new PhD thesis by Teena Chauhan. The thesis will be defended at UNIS on Thursday 27 August 2015.

The most important animal in the Arctic

17 November 2014

Without copepods the entire Arctic marine ecosystem would probably collapse. They hold a key position in the food web as a link between phytoplankton and larger animals in the Arctic. In a new PhD thesis by Daniel Vogedes unknown life history aspects of three copepod species are revealed. Vogedes will defend his thesis at UNIS on Wednesday 19 November 2014.

New light shed on dayside Aurora

28 August 2014

The dayside aurora is less studied and less well understood than the nightside counterpart. In a doctoral thesis by UNIS PhD candidate Jeffrey Holmes, further understanding of precipitating protons in the dayside aurora is revealed.

Why do we know so little of the comb jellies?

23 April 2014

One of the world’s oldest animal species, the comb jellies, has kept their secrets up to the present day. In a recent PhD thesis, Sanna Majaneva studied the life of the Arctic comb jelly in the Baltic and in Svalbard.

Pollutants in the Arctic

18 November 2013

Some pollutants are buried deep into the soil, snow and ice, but are transported into the sea by meltwater runoffs. How much of these contaminants end up in the ocean and how does this influence the take-up of pollutants in the Arctic marine food web? That’s what Pernilla Carlsson, PhD candidate in environmental chemistry, has tried to find out. Thursday she will defend her PhD at UNIS.

New understanding of snow avalanches

7 October 2013

PhD candidate Louis Delmas has studied the influence of climate parameters on snow in order to better predict spontaneous snow avalanche releases in the Longyearbyen area. Delmas defended successfully his PhD thesis on Wednesday 9 October at UNIS.

New insights into ice ridge keels

1 October 2013

Ice ridge keels can potential damage the subsea installations in the Arctic. PhD candidate Aleksey Shestov has investigated the thermodynamic consolidation of ice ridge keels and developed a mathematical model for ice ridge dynamics. Shestov will defend his PhD thesis on Thursday 3 October at UNIS.
