In Fall 2025 the Hawaiʻi Abyssal Nodules and Associated Ecosystems Expedition, led by USGS scientists, will investigate the geology, minerals, and environmental setting of the deep seabed offshore Moku o Keawe (Hawaiʻi Island) in the U.S. Exclusive Economic Zone. This work is part of ongoing collaborative efforts with BOEM and NOAA.

Most recent time-averaged image from Sand Key, Florida. The images are used to examine a range of coastal processes including shoreline position, the presence of an offshore sandbar, and the extent of wave runup on the beach. Camera hosted by Dan's Island Condo.

Time-averaged images, which represent the time-mean of all the images collected during a video, are used to identify areas where waves are breaking, which show up as bright white bands in the image.

Two video cameras are installed atop a utility pole near the northernmost point of land in the United States at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes.
