Images of Madeira Beach, Florida, from video taken June 20, 2017

Detailed Description

Views of Madeira Beach, Florida, produced from a 17-minute video shot on June 20, 2017. Left: Snapshot, or first frame of video. Right: Time-averaged image, sometimes called a “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during the 17-minute video. The pale band offshore shows where a sand bar caused waves to steepen and break. On the beach, the line between wet and dry sand shows the maximum wave runup during the video.
