The rapid warming of the Arctic has global ramifications. Modifications to ocean circulation and regional climate patterns linked to Arctic ice melt are affecting trade, transportation, energy resources, infrastructure, coastal ecosystems, fish and wildlife, sea level and coastal erosion, security, demographics, and cultural identities -- not only in the Arctic but also in midlatitude regions, including the North Atlantic. This session invites research that 1) studies midlatitude changes in ocean and atmospheric processes resulting from a warming Arctic, 2) develops research infrastructure needed to observe Arctic–midlatitude links and/or 3) identifies how ocean and atmospheric changes will affect both Arctic and midlatitude communities. The session focuses on highlighting shared research assets and collaboration networks, with the intention of facilitating convergent research initiatives connecting the Arctic and midlatitudes. We especially welcome research linking the North Atlantic sector of the Arctic with the eastern coast of North America.
