Her Thesis title was: “Zooplankton communities, food web structures and sympagic-pelagic coupling in the Svalbard-Barents Sea marginal ice zone.”
The overall goal of the study has been to increase our knowledge of Arctic marine ecosystems and the physical and biological factors that influence their structure, and she used a combination of stable isotopes and fatty acid trophic markers to quantify levels in the food chains and their energy sources.

The study has been a part of the project: ”On Thin Ice? Climate influence on energy flow and trophic structure in Arctic marine ecosystems”, led by Akvaplan-niva and financed by the Research Council of Norway (AKTØK/NORKLIMA program).

Opponents were Dr. Holger Auel (Marine Zoology, University of Bremen, Germany) and Dr. Tone Falkenhaug (Institute of Marine Research, Flødevigen), and the committee was headed by Dr. Jørgen Schou Christiansen (Norwegian College of Fishery Science, University of Tromsø). Supervisors were Dr. Haakon Hop (NP), Prof. Stig Falk-Petersen (NP/NFH), Dr. Michael L. Carroll (Apn) and Assoc. Prof. Else Nøst Hegseth (NFH/UiTø).
