Drifting icebergs can be a serious threat to Arctic and subarctic offshore activities. PhD candidate Renat Yulmetov analysed the drift of icebergs in broken sea ice and investigated the possibility of iceberg towing in sea ice to protect offshore structures. Yulmetov will defend his PhD thesis on 12 January 2017 at UNIS.

Silje Eriksen Holmen has investigated temperatures in the middle atmosphere (the mesosphere) over Longyearbyen and Tromsø and has found that temperature varies periodically according to atmospheric wind patterns and waves. Holmen will defend her PhD thesis at UNIS on 19 December 2016.

Meroplankton are important in Arctic marine environment, but their dynamics and ecological role in marine coastal ecosystems are poorly understood. Eike Stübner has investigated these benthic invertebrate larvae and her research shed some light on the function of meroplankton in the Arctic. Stübner will defend her PhD thesis at UNIS on 14 December.

The Greenland ice sheet is not entirely white. Parts of the ice sheet have darkened since 1996, leading to increased melting. PhD candidate Thomas Gölles has developed tools to study the interplay of particle accumulation, ice flow and ice melt. Gölles will defend his dissertation at UNIS on 29 September.

Sunil Mundra has investigated fungal richness and community structure, and their drivers at different spatial and temporal scales in the High Arctic region (Svalbard), using next generation sequencing methods. Sunil Mundra will defend his PhD thesis on 16 December at UNIS.

PhD candidate Srikumar Roy has investigated the seabed fluid flow, seepage processes and features in Isfjorden, the largest fjord system of Svalbard. His research has helped to understand the geological controls on various fluid migration pathways and processes existing in the Norwegian Arctic fjords. Roy will defend his PhD thesis at UNIS on 6 November 2015.
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.

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.
