Screenshot of an idealized animation of tsunamis produced by the 15 January 2022 eruption of Hunga Tonga-Hunga Haʻapai volcano in the Kingdom of Tonga. View to the north-northeast. The fastest water wave to radiate away from the eruption is being pushed by an atmospheric wave triggered by the explosion.

A digital elevation model (DEM) was created from underwater images collected at Eastern Dry Rocks coral reef near Key West, Florida, in May 2021 using the SQUID-5 camera system. The underwater images were processed using Structure-from-Motion (SfM) photogrammetry techniques into a classified two-class ('unclassified' and 'low noise') 3D point cloud.

None the worse for wear, a plastic, ocean current drifter disk, originally released off Barter Island in Alaska, was discovered on the coast of Scotland 37 years after its initial release into the ocean.

This image from a video camera pointed at the coast tracks the brightest pixels in the camera view over 10 minutes of video. The resulting image is useful for identifying features such as the position of maximum wave run-up on the beach, the position of all breaking waves, and sea-state.

Two coastal observing video cameras are installed atop a utility pole near the northernmost point of land in the United States: at Nuvuk (Point Barrow), Alaska.

Point Barrow, Alaska, or Nuvuk, is the northernmost point in the United States. USGS has set up video cameras, mounted to the pole shown here, to study sediment movement and wave dynamics along this dynamic coastline.
