Graham Gilbert has studied fjord-valleys in the high Arctic and investigated sedimentary characteristics and permafrost development. Gilbert will defend his PhD thesis Wednesday 17 January at UNIS.

Åsmund Skjæveland has studied the details of the atmospheric mechanisms that take the energy from the northern lights and create warm and vertical winds. Skjæveland will defend his PhD thesis on Friday 12 May at the University of Oslo.

Why do zooplankton migrate up and down the water column during Arctic dark season when there is apparently constant darkness? PhD candidate Julie Cornelius Grenvald has examined the Diel Vertical Migration (DVM) of zooplankton during the polar night and reveals several and complex migration patterns. Grenvald will defend her thesis on 9 May at the University of Tromsø.

The Earth’s cusp region is believed to be the main place of transport of the magnetosheath plasma into the ionosphere. PhD candidate Xiangcai Chen has analysed a long-term ground-based optical aurora and SuperDARN HF radar data over Svalbard to further understand the dynamics of the reconnection plasma process in the cusp region. Xiangcai will defend his PhD thesis at UNIS on 28 February.

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.
