Head of the Meadow Beach video camera 1 variance image

Two video cameras are mounted on a bluff near Head of the Meadow Beach, Cape Cod National Seashore, North Truro, MA. One camera looks directly offshore (north east), and the second looks alongshore (north-northeast). 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. Today’s most recent image from camera 1, pointing alongshore, is shown here. Please note that it takes 10 minutes for the images to be posted once they are collected by the camera. (Larger Version)
