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.
Using Video Imagery to Study Sediment Transport and Wave Dynamics: Nuvuk (Point Barrow)
Two coastal observing video cameras were installed atop a utility pole near the northernmost point of land in the United States, at Nuvuk (Point Barrow), Alaska. The cameras pointed northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas, and were used to observe and quantify coastal processes such as wave run-up, bluff erosion, movement of sandbars and ice floes, and sediment entrainment and transport by ice.
These cameras were decommissioned in September 2025 because of rapid erosion at the tower location. No new images or wave data will be collected at this location. The images below are the final photos captured prior to decommissioning.
Every half hour during daylight hours, the cameras collected snapshots and video for 10 minutes. Examples of the types of images collected are shown below.
For water level and meteorological observations near the Nuvuk station, visit the Prudhoe Bay NOAA Tides & Currents site.
Currently, USGS video cameras are active at these locations:
- Dream Inn hotel in Santa Cruz, California
- Head of the Meadow Beach, Massachusetts
- Marconi Beach, Massachusetts
- Norton Sound, Unalakleet, Alaska
- Sunset State Beach, California
Snapshot
The snapshot is the first frame of the video, just like a standard photo.
Timex (time-exposure) images
A timex is a time-averaged image of all frames, smoothing away surface waves and determining the location of persistent wave-breaking (indicative of shallow sandbars).
Variance images
A “variance” image shows the standard deviation of pixel intensity throughout the video, and it is useful for determining how much variation or movement is occurring at a given location.
Bright images
A “bright” image shows the brightest pixel values throughout the video, useful for identifying the position of maximum wave run-up on the beach, position of all breaking waves, and sea-state.
Dark images
A “dark” image shows the darkest pixel values throughout the video, useful for tracking sediment plumes, tracking floating debris, and filtering out breaking waves.
