An remotely piloted aircraft (RPA) or drone, equipped with a camera, sits on the Arctic tundra awaiting a radio signal that tells it to fly.

Example of a low-oblique photograph taken with an unmanned aerial system (UAS), or drone, of the coastal bluffs of Barter Island on North Slope of Alaska. The photographs from different time periods can be compared, using a technique called structure-from-motion photogrammetry, to measure changes in the coastal bluffs.

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.

A global positioning system (GPS) sits on a tripod and is used to accurately pinpoint the center of a target that itself is used for photo rectification with aerial photos. 

Example of a thermal photograph of Barter Island's bluffs, on the North Slope of Alaska. Two USGS scientists stand waving on the right side of the photo. Lighter areas are warmer, darker areas are colder. Thermal photography makes it easy to detect areas of permafrost, or the lack thereof.

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.
