The Nansen Legacy

Populærvitenskapelig sammendrag

An ice-free Arctic is gradually emerging. Wintertime sea ice retreat is to date most pronounced in the Barents Sea. It is imperative for the Norwegian research community to rise the scientific and exploratory legacy of Nansen and move poleward through the northern Barents Sea.

 

To understand complex couplings between atmosphere, sea ice, ocean currents and ecosystems, Arctic expertize from ten Norwegian research institutions has initiated a historic effort. Over six years, scientists in the Nansen Legacy will work across disciplines and institutions to provide knowledge on how the marine ecosystem respond to climate and human activities. The goal is to understand how the physical environment function and impact the ecosystem today, and what we can expect in the future. A new ice going research vessel, Kronprins Haakon, and new technology, enable data collection throughout the year and in unaccessible places. A climatic gradient through the Barents Sea, from ice-free waters in the south to an ice covered Arctic basin in the north, shows how organisms, from bacteria and algae to fish and seals, respond to different climatic conditions. Geological cores reveal past variability, and climatic models point to the future. Increased activity follows the ice retreat. Knowledge facilitates future resource management in the north. Better observations improve the weather forecast and increase safety. The Nansen Legacy will educate a minimum of 50 new Polar researchers  and engage users and the public to discuss status and changes in the Arctic, and why it relates to our society.

 

The Nansen Legacy is a partnership between the Universities in Oslo, Bergen, Trondheim and Tromsø, UNIS, The institute of Marine Research, The Norwegian Polar Institute, The Meteorological Institute, Nansen Environmental Remote Sensing Center and Akvaplan-Niva. The budget is 740 mill kr, with 50% in-kind from the participating institutions. The Nansen Legacy initiates a new era in research organisation.  

Vitenskapelig sammendrag

The Nansen Legacy is a joint, concrete and ambitious plan to follow Nansen’s example in exploring the Arctic. To establish a holistic understanding of a changing Arctic Ocean and ecosystem, the project will provide the scientific knowledge base needed for future sustainable resource management in the transitional Barents Sea and the adjacent Arctic Basin.

 

An ice-free Arctic is gradually emerging. The winter sea ice retreat is to date most pronounced in the Barents Sea, the Atlantic gateway to the Arctic. As sea ice retreats and technology and infrastructure improves, it is imperative to rise to the scientific and exploratory legacy of Fridtjof Nansen and move poleward through the Barents Sea. The Norwegian Arctic research community, joint in the Nansen Legacy, will take on Nansen’s tasks with several approaches. First, through a number of multidisciplinary cruises, a holistic “ground truth” will be established for the physical environment and the ecosystem in the northern Barents Sea, and adjacent Arctic Basin. Secondly, there will be an assessment on the impact of human activities in this region, with an emphasis upon ocean acidification, pollution and the impacts of fisheries. Thirdly, using scientific models, a 2020-2100 outlook for the expected state of climate, sea ice, and ecosystem will be provided. This include development of multi-perspective scenarios for the northern Barents Sea developed by scientists and users in a 2050 perspective. Fourthly, in order to improve safety for people and commercial operations, improved polar weather forecasts will be developed. Fifthly, to ensure open data availability in accordance with national and international standards, the Nansen Legacy will improve, secure and operationalize national data archives. At last, most importantly, the core aspect will be the emphasis on recruitment and training of the next generation of cross-disciplinary Arctic researchers, and on engaging and educating the public.
