There is increasing scientific recognition that changes to the Arctic freshwater systems have produced, and could produce even greater, changes to bio-geophysical and socio-economic systems of special importance to northern residents and also produce some extra-arctic effects that will have global consequences. To address such concerns, a scientific synthesis will be conducted that focuses on the various Arctic freshwater sources, fluxes, storage and effects. The range of sources and fluxes to be assessed include: atmospheric vapour transport, precipitation-evaporation, river flow, ablation of glaciers and ice caps, sea ice formation/ablation and marine (low-salinity water) exchanges. Extra-Arctic sources and fluxes from lower latitudes will be included, given their relatively large influence on the overall Arctic freshwater budget, as well as potential flux regulators (e.g., flow from the Greenland Ice Sheet).
Jointly organized with the Climate and Cryosphere project (link to: http://www.climate-cryosphere.org/activities/targeted/afs) and the Arctic Monitoring and Assessment Programme (link to: http://www.amap.no), the synthesis will be coordinated through a set of international workshops and meetings, with past open community meetings at the AGU Fall Meeting in San Francisco in 2012 and at the ASSW 2013.
The first workshop was held in Stockholm on 11-12 November 2013, hosted by the Swedish Secretariat for Environmental Earth System Sciences (SSEESS) at the Royal Swedish Academy of Sciences.
Participants: Terry Prowse, Johanna Mård Karlsson, Arvid Bring, Jenny Baeseman, Volker Rachold, Lars-Otto Reiersen, Timo Vihma, James Screen, Ming-Ko Woo, Irina Fedorova, Arne Instanes, Vasily Kokorev, Margareta Johansson, Camille Lique, Joseph Culp, Willem Goedkoop
This meeting gathered a number of component co-leads for the Arctic Freshwater Synthesis (AFS) for discussions on AFS structure, goals and process. Specific tasks were to move forward with identifying recent advances and knowledge gaps in the Arctic freshwater system, identifying synergies between components that can generate new knowledge from the AFS, and plan for the continued process. November 11 was spent on presentations by participants and discussions on topics for integrating the various components. On November 12, the workshop finished an outline of the main topics and their integrating links for each component. Additionally, the continued process and form of scientific deliverables was discussed.
The community will be informed of progress at upcoming international conferences, including AGU Fall Meeting in December 2013 and the ASSW in Helsinki, Finland, in April 2014. Researchers wishing to contribute to the synthesis are welcome to contact IASC for more information.
