The USGS and partners study the effects of climate change on the Greater Yellowstone Ecosystem. This sunset image was taken from Steamboat Lake, Wind River Indian Reservation, Wind River Range, Wyoming.

A closer look at the water surface. While most of the surface has a yellow-green color, portions along the shoreline have a blue color and seem to correspond to areas of water upwelling. USGS photo by M. Patrick.

Material filling the dissolved voids includes clasts of wall rock as well as beach sediments being washed into the voids. The lower structure on the left is about 0.7 m (2 ft) wide and 1.5 m (5 ft) high. Note the fracture alignment above the void structure on the right.

Flooded mangrove forest in Micronesia.

The USGS and partners are studying how mangrove forests in the Federated States of Micronesia may respond to sea-level rise over the coming century. Their projections will help Micronesian communities plan for the future.

Alongshore view of the Barter Island permafrost bluffs, along the north coast of Alaska in the Arctic Ocean.

Gigantic chunks of perafrost coastal bluffs tumbled down onto the beach along Barter Island on the North Slope of Alaska. A USGS scientist drives past them, seeking good locations to place instruments and markers that will be used in photographic analysis.

Along the stretch of coastal bluffs of Barter Island, North Slope of Alaska, a new drainage gully developed between September 2018 and September 2019. USGS scientists have been measuring permafrost degradation, coastal erosion, and flooding hazards on and around Barter Island for the last decade.
