Abstract

Abstract: In response to a joint request from the World Climate Research Program's Climate and Cryosphere Project, the International Arctic Science Committee, and the Arctic Council's Arctic Monitoring and Assessment Program, an updated scientific assessment has been conducted of the Arctic Freshwater System (AFS), entitled the Arctic Freshwater Synthesis (AFS Σ ). The major reason for joint request was an increasing concern that changes to the AFS have produced, and could produce even greater, changes to biogeophysical and socioeconomic systems of special importance to northern residents and also produce extra‐Arctic climatic effects that will have global consequences. Hence, the key objective of the AFS Σ was to produce an updated, comprehensive, and integrated review of the structure and function of the entire AFS. The AFS Σ was organized around six key thematic areas: atmosphere, oceans, terrestrial hydrology, terrestrial ecology, resources and modeling, and the review of each coauthored by an international group of scientists and published as separate manuscripts in this special issue of Journal of Geophysical Research‐Biogeosciences. This AFS Σ —Introduction reviews the motivations for, and foci of, previous studies of the AFS, discusses criteria used to define the domain of the AFS, and details key characteristics of the definition adopted for the AFS Σ . Key Points: The AFS can produce significant intra‐Arctic and extra‐Arctic effects Programs studying the AFS have evolved over the last half century Defining the domain and characteristics of the AFS are critical to its study
