A polar bear stands on a low-lying barrier shoal near the Huluhula River on the Beaufort 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.

Coral atolls are normally long, thin bars of white sand that rise just a few meters above sea level. The island or island group surrounds a hollow center where a volcanic peak once was. The atoll shown in this photo-like satellite image is the island of Tureia, in French Polynesia, in the South Pacific Ocean.
