Collaboration Research collaboration is of great importance for knowledge development. High quality and innovation in research is ensured through linking professional environments. Over the decades, the Nansen Center has built a large network within national and international research environments and participates in a number of national and international networks. The collaboration takes place both between individual researchers and at institutional level. We are constantly developing our collaboration platforms and networks, to develop our research and expertise, and to make it available to relevant environments and sectors. National collaboration The Nansen Center collaborates closely with Norwegian research environments. A long-standing and important collaborative project within climate research is the Bjerknes Centre for Climate Research, where the other participants are the University of Bergen, NORCE and the Institute of Marine Research. We are partners in Climate Futures, which develops climate forecasts for climate risk management, and Smart Ocean, which develops wireless underwater communication along the coast of Norway – two centers for Research-based Innovation. Furthermore, the Nansen Center participates in the national research projects in the Barents Sea and the Arctic Ocean; Nansen Legacy and GoNorth. Many years of collaboration with the Norwegian Meteorological Institute and the Institute of Marine Research in ocean modelling and marine services have formed the basis for joint deliveries into international services. International collaboration Research increasingly involves international collaboration, particularly within scientific disciplines. A large part of the research activity at the Nansen Center is carried out through international cooperation, primarily in the EU. A key collaboration platform for the development of ocean models and marine services is the Mercator Ocean International – MOI, a research company which the Nansen Center has a co-ownership in. The European Commission has delegated responsibility for the operational marine observation and forecasting system in the Copernicus program to the MOI, and the Nansen Center supplies a central part of services together with the Meteorological Institute and the Institute of Marine Research. Like in other disciplines, our climate research is carried out in close collaboration with other European climate centers, while in the observation-based activities we particularly collaborate with North American institutions. The international Nansen centers The Nansen Center aims to deliver environmental and climate research of high quality and with relevance for the world community. The climate challenges are global in nature, and international cooperation is therefore essential both for the development and sharing of new knowledge, and for it to be used locally, regionally, and globally. As a contribution to such competence building and mutual knowledge development, the Nansen Center has taken the initiative to establish five international sister centers. The centers have served as a platform for research collaboration and knowledge exchange, and as well as an arena for establishing networks. We collaborate with the centers in joint research projects, and joint publication of scientific results is encouraged. Exchange visits for researchers and students are also part of the collaboration. Interaction with the center in Russia has been put on hold as a result of the situation in Ukraine. Nansen International Environmental and Remote Sensing Center St. Petersburg, Russia, established in 1992. NIERSC is a collaboration between Russian, German and Norwegian academic partners, organized as an independent research foundation. The center focuses on polar climate, sea-ice, and ocean studies. Nansen-Zhu International Research Center Beijing, China, established in 2003. NZC is a joint venture between Chinese and Norwegian academic and university partners. The center is organized as a research department at the Institute of Atmospheric Physics, under the Chinese Academy of Sciences. The research focus is global, regional, and teleconnections in climate change and modelling. Nansen-Bangladesh International Centre for Coastal, Ocean and Climate Studies Dhaka, Bangladesh established in 2012. NABIC is a joint venture between local and Norwegian partners at the Bangladesh Center for Advanced Studies. The center's research focus is oceanography in the Bay of Bengal, and regional climate change and effects. Nansen Environmental Research Centre India Kochi, Kerala, India, established in 1999. NERCI was established as a non-commercial and accredited research company, with the Nansen Center and local Indian center staff as shareholders. The center focuses on studies of climate and marine ecosystems in southern Asia. Nansen-Tutu Research Centre for Marine Environmental Research Cape Town, South Africa, established in 2010. NTC is a joint venture between South African, French, American, and Norwegian academic and university partners. The center is organized as a research unit at the Department of Oceanography at the University of Cape Town and focuses on studies of the Agulhas and the ocean currents around southern Africa.
