Unalakleet video camera 2 bright image
Two video cameras overlook the coast from atop a windmill tower in Unalakleet, Alaska where they look westward over Norton Sound. Every half hour during daylight hours, the cameras collect snapshots and video for 10 minutes. Today’s most recent image from camera 2 is shown here. Please note that it takes 10 minutes for the images to be posted, once they are collected by the camera. This bright image shows the brightest pixel values at each location throughout the video, useful for identifying the position of maximum wave run-up on the beach, position of all breaking waves, and sea-state.
