Radionuclide distribution and environmental safety (Arctic) The management of anticipated modifications to sea ice patterns and more frequent permafrost thawing due to intensified global warming in the Polar regions, and the need to deal with the potential elevation of radiological dose for Arctic residents and wildlife, particularly through increased Rn exhalation from permafrost melting, potentially resulting in a two- to threefold increase in the dose. Climate predictions from NorESM are available in the Norwegian Research Data Archive (NIRD Archive) but are unlikely to be directly exploitable by environmental managers. At present, data from NorESM is “dumped” from the High-Performance Computing (HPC) to the NIRD archive with minimal metadata, which makes it difficult for non-expert users to understand and reuse the data for CCA. This challenge is further complicated by the large size of data sets and their preservation in a format unfamiliar to most users.
