Caribou Along Alaska's Coast
This photograph shows three caribou escape the mosquitos on the mudflats of Kasegaluk Lagoon on the Chukchi Sea coast of Alaska. Coastal erosion along the Arctic coast is chronic, widespread and potentially accelerating, posing threats to infrastructure important for defense and energy purposes, natural shoreline habitats and nearby Native communities.
