Zooplankton migration patterns in the Polar night

5 May 2017

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.

A dynamic study of the ionospheric footprint of the cusp/cleft over Svalbard

24 February 2017

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.

Icebergs in broken sea ice

6 January 2017

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.
