    Berge has developed a large and strong national and international network. Nationally, this is most evident by being the leader of the ARCTOS research network (www.arctos.uit.no) since 2012. Internationally, Berge is  a member of the leader group of the Arctic Science Partnerships programme (www.asp-net.org), a network that now include key Arctic institutions from Canada, Greenland, Denmark, Sweden, Norway and Germany. Individual collaborators include Professor Geir Johnsen (NTNU, Norway – bio-optics and eco-physiology in relation to primary production, 19 co-authorships),  Professor Finlo Cottier (SAMS, UK – physical oceanography, 17 co-authorships), Professor Asgeir Sørensen (Director CoE AMOS, Norway – cybernetics, autonomous platforms, 4 co-authorships), Professor Paul Renaud (APN, Norway – ecosystem structure and benthic coupling processes, 15 co-authorships), Professor John Cohen (UDel, USA – bio-optics and ecophysiology related to detection of light, 5 co-authorships), Professor Stig Falk-Petersen (APN, Norway – trophic interactions, pelagic ecosystems, 23 co-authorships), Dr Maxime Geoffroy  (St. Johns, Canada – bio-acoustics, 7 co-authorships).

    SCIENCE COMMUNICATION
    Berge was awarded the Fram Centre and UiT prizes for excellence in science communication in 2015 and 2016, respectively, much due to the Polar Night exhibition (https://uit.no/ressurs/uit/mediebok/polarnight/) that has been on display in both Norway (Polarmuseet Tromsø, Svalbard Museum Longyearbyen), Russia, Canada and in the US (full scale in Anchorage, Alaska, reduced display in Washington and Boston). Berge also has an outstanding record from communication in national and international media (newspapers, TV, radio, and magazines, see outreach summary on www.mare-incognitum.no).

    Berge has had an increasingly high scientific production during his career, with an average of more than 11 papers each year since 2010. According to Web of Science Berge is the fifth highest ranking researcher in the world based on number of scientific articles with “Arctic” as the keyword during the last 10 years. During this period his main research activity and most important publications have been centered around biological processes during the Arctic polar night and winter. Since much of this work represents pioneering achievements in a new branch of marine biological science, citation rate and impact of these papers are likely to increase substantially in the years to come.
    Expeditions and field experience
    Berge has headed 2-3 research expeditions in the Arctic each year since 2003. This includes serving as PI on annual teaching/research expeditions with the RV Helmer Hanssen each autumn (UNIS courses AB202, 320 and 321) and since 2010 annual Polar Night land- or ship-based research expeditions. Berge has also lead extensive land-based campaigns, most notably the expeditions to Rijpfjorden (5x2 weeks) as part of the International Polar Year 2007-2008, and numerous smaller expeditions in and around Svalbard. Participated on a research expedition to the Antarctic on RV Polarstern in 2002.
