This Town Hall meeting sought community input for developing an Arctic Synthesis Collaboratory, a concept arising from a 2007 workshop and discussions in the arctic research community. The Collaboratory concept is an "umbrella" framework that fosters interactions among arctic scientists and other stakeholders, integrates data analysis and modeling, develops outreach, education, and policy-relevant resources, and provides training and professional development. Charlie Vörösmarty presented on the Collaboratory concept and then opened the floor for discussion on community needs and concerns, as well as organizational and implementation issues.
