The purpose of the workshop is to exchange information, knowledge and experiences of different local environmental observation projects across the circumpolar Arctic. Experienced observers and technical experts from North America will meet with delegates from across the circumpolar region, some whom already participate in observation networks in their region, to learn about the observer networks. The results of this workshop will summarize existing community based observation systems in Arctic regions, mechanisms for connecting Traditional Local Knowledge to outside technical experts, identify gaps that the CLEO project could work to fill, and initialize a framework for establishing a circumpolar local environmental observer network.
