The mission of the Arctic Coastal Risk Network is to facilitate collaboration and convergence of research on Arctic coastal hazards/risks, welcoming contributions from natural sciences, social sciences, and coastal community members. Our two main activities in support of the mission are (1) the development of the network (via website and outreach), and (2) the demonstration project on how (a) to define and communicate coastal risk, (b) how to determine community knowledge, preferences and values, and (c) how to make decisions under uncertainty.
