6. A detailed study of auroral fragments
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : Aurora occurs in various shapes, one of which is the hitherto unreported phenomenon of auroral fragments. For three periods of occurrence of these fragments their properties were studied in detail during this master’s thesis, using mainly ground-based instrumentation located near Longyearbyen on Svalbard, Norway.

7. Exploring Agroecology : agroecology, urban agriculture and farming in secluded areas
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Agroecology, due to its framework and prerequisites, is a limited set of principles with lacking flexibility. Its objective is to create fairer food networks, that are sustainable, on a global scale yet it is seldom seen in practice. Its unconventional means are not convincing enough to engage larger amounts of people who partake in agriculture. LÄS MER
8. Förnybar energi på Svalbard
M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapSammanfattning : This degree thesis investigates the possibilities of producing food inside a container at Svalbard, using renewable energy and energy storage. The idea was to be able to place the container at remote places without the need of being connected to the grid. We chose Svalbard, where it is cold and the sun is shining 24 hours a day at summertime. LÄS MER
9. Characterization of Wind Channeling Around Longyearbyen, Svalbard
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Due to climate change and arctic amplification, the avalanche activity is expected to increase at higher latitudes (Hall et al., 1994). The arctic settlement of Longyearbyen, Svalbard, situated inside the valley Longyeardalen, is yearly threatened by avalanche activity (Eckerstorfer & Christiansen, 2011a). LÄS MER
10. Local pollution and the risks of OPFR, PBDE and PFAS to the marine ecosystem outside Longyearbyen and Barentsburg in Svalbard
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : Most of the ecotoxicological research conducted in the Arctic until today has focused on long range transport of pollutants, while fewer studies on local pollution have been published. The aim of this study was hence to investigate if local pollution of organophosphorus flame retardants (OPFRs), polybrominated diphenyl ethers (PBDEs) and perfluorinated alkylated substances (PFAS) occurs outside two settlements in Svalbard; Longyearbyen and Grønfjorden.
