In 2021, the ASSW will take place in Lisbon under the theme: “The Arctic: Regional changes, Global impacts”. The event will bring together scientists, Indigenous Peoples, Arctic community members, and Arctic science stakeholders to present and discuss the most recent advances on Arctic knowledge across disciplines, from the natural sciences to the humanities. The ASSw2021 will also be an opportunity to foster research synergies between both Polar Regions, with sessions that target both Poles welcomed. The Arctic community is invited to chair and present session proposals of relevant topics in all science fields, both specific and cross-cutting, framed in the overall conference theme.
