Coastal Hazards

Flooding, Erosion, and Permafrost Degradation—Alaska Communities

Alaska's Environmentally Threatened Communities StoryMap] Access this StoryMap here

144 communities in Alaska are threatened by flooding, erosion, and permafrost degradation. DGGS tracks data and tools to support decision-making by agencies, Tribal organizations, communities, and partners for the collective "all hands on deck" response to environmental threats.

About the Program

Alaska's extensive shorelines are incompletely mapped and poorly monitored for the evaluation of coastal dynamics. The DGGS Coastal Hazards Program is engaged in ongoing investigations that will expand our understanding of how the coastline has evolved and how it will respond to hazardous events and long-term changes. This program is dedicated to fostering scientific partnerships that will improve the quality and quantity of the critical baseline data that are necessary to fuel informed decision-making throughout the state.
