One of the most important activities of the Nordic Volcanology Center is the research fellow program. Every year five young Scandinavian geoscientists are invited to do a research project in Iceland.
In 2013-2014 the following research fellows with the projects have been appointed:

I did observe the Grímsvötn 2011 eruption, experienced the darkness during a heavy tephra fall and measured and sampled freshly fallen tephra. This direct tephra encounter gave me a new vision on tephra and my “pet project” these days is to observe what changes a tephra deposit goes through before it is incorporated in the soil and becomes a measurable tephra layer in soil sections.

My background is in tephra studies, i.e. tephrochronology and also paleoclimatologic research. In my B.Sc. project at the University of Iceland I studied a tephra layer produced in an eruption in Katla volcano in 1755 AD. In my Cand. Scient. (M.Sc.) studies at the University of Bergen, Norway, my research was focused on studying the environmental and climatic changes in Sognesjøen, outer Sognefjord, western Norway, during the last ~11.000 cal yrs BP from marine sediments. In my PhD project at the University of Iceland, I worked on tephra layers in marine sediments from the North Icelandic shelf with the purpose of establishing a tephrochronological framework and gather information on volcanic activity in Iceland for the last 7050 years.
Research project at Nordvulk
My research project at Nordvulk titled; “Holocene tephra stratigraphy of a continuous lake sediment sequence from Lake Lögurinn, Iceland, deals with identification and analysis of tephra layers in lake Lögurinn to establish a tephrochronological framework for dating and as a source of information on volcanism in Iceland. The aim of the project is to produce a detailed tephra stratigraphical record for the entire Holocene time period in eastern Iceland that will hopefully significantly contribute to and improve current knowledge on Icelandic volcanoes and volcanic systems, especially concerning the early Holocene time period.
My project is connected to a project called the Lagarfljót project which aims at obtaining a general glacial history of Vatnajökull, the surge and melt-water history of Eyjabakkajökull, and a detailed Holocene environmental history of eastern Iceland read from the sediments of lake Lögurinn. Therefore the tephra stratigraphical record from Lake Lögurinn will provide a chronological framework for the environmental history of Vatnajökull.
Today I am a Danish geology-geoscience graduate. My educational résumé contains a Bachelor’s degree in geology-geophysics and a Master’s degree in geology-geoscience from University of Copenhagen.
My Master’s project focused on mantle melting. It revolved around the Cape Verde archipelago. The Cape Verde Islands are situated on the biggest hotspot on our planet, which makes them very appealing for mantle studies. My modeling was based on the petrological interpretation of major-, trace-, and isotopic element data. It was set within the framework of thermodynamics and experimental petrology data.
During my Master’s I also spent 6 months on studying active volcanism at University of Hawaii. There I gained knowledge of the many aspects of volcanology. And I also got to baptize my geo hammer in the red-hot pahoehoe flows. Thus older and wiser I finished my degree.
Then I got involved with teaching and public outreach for a few years. I worked at Danish natural history museums and developed new geological teaching programs for visiting schools. The didactics were based on the intriguing cooperative learning and multi-voiced classroom theories.
I believe that good communication skills are paramount in relation to hazard research and teaching has a very big place in my heart.
My aim is to evaluate the distal hazard potential of hydromagmatic basaltic explosive eruptions. I am primarily interested in eruptions that have reached the European area, such as the recent eruptions of Eyjafjallajökull 2010 and Grímsvötn 2011 and those of Katla in 1625 and 1755. I look at the local tephra distribution in Iceland from specific eruptions and then I study the morphology of the tephra grains. The results are then to be used in tephra dispersal and hazard models. My project is co-funded by NORDVULK and the University of Copenhagen.
