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.

USGS scientist Chelsea Stalk stands on a floating sled that enables sub‐bottom surveying in shallow water, nearshore, and shore‐face environments. The sled is equipped with an EdgeTech SB‐512i CHIRP system and single‐beam sonar. This equipment is used to collect seismic sub‐bottom profiles and single‐beam bathymetry.

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.

USGS scientists use specialized equipment to measure sediment dynamics in nearshore and coastal systems. Access by boat is limited in these areas, so personal watercraft are equipped with GPS and echosounders to collect bathymetric data. Seismic sleds are pulled along transects from the beach across the water to measure changes in sediment type below the water.

This sequence captured on August 31 begins with a close-up of the fumaroles on the north side of Halema‘uma‘u, then shows a broader view of the crater with the water pond at the bottom and a close-up of steaming and ripples on the water surface. USGS video by M. Patrick, 08-31-2019.

USGS wildlife biologist, Anthony Fischbach, piloting an unmanned aerial system (UAS) for use in surveying walruses while they rest on shore. The UAS is flown above 300 feet altitude such that it enables survey data collection with minimal risk to the walruses.

This timelapse video covers about 30 minutes of activity at the water pond in Halema‘uma‘u at the summit of Kīlauea. Water appears to be flowing into the pond from several locations, including the southern boundary (right side in this image). A small amount of material is also seen floating on the surface at the eastern end of the pond (top of image).

HVO field engineers and staff conducted quarterly work at a deep borehole, known as the Keller Well, at the summit of Kīlauea Volcano today (Sept. 24). They lowered a sensor into the well to measure the distance between the ground surface and the top of the water table, which was 505 m (1657 ft) below the ground surface today.
