Meroplankton in Svalbard waters

9 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.

Impurities of glacier ice

23 September 2016

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.

Unravelling hidden designer of Arctic vegetation

11 December 2015

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.

Looking deeper into the seafloor of Isfjorden, Svalbard

3 November 2015

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.

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.
