Head of the Meadow Beach video camera 2 dark 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 “dark” image shows the darkest pixel values throughout the video, useful for tracking sediment plumes, tracking floating debris, and filtering out breaking

Marconi Beach video camera 2 variance image

Two video cameras are mounted on a bluff above Marconi Beach, Cape Cod National Seashore, Wellfleet, MA. Every half hour, the video cameras collect imagery for 10 minutes. This is the “variance” image, showing the standard deviation of pixel intensity throughout the video, useful for determining how much variation or movement is occurring at a given location. View looks

Seafloor map of Puerto Rico Trench

A NOAA image of the bathymetry north of Puerto Rico. Two ancient submarine landslides are visible as head scarps (labeled Loiza and Arecibo Amphitheaters). Seafloor fissures are indicated by black arrows, and dashed lines outline debris flows from past failures. Map annotated by Uri ten Brink, USGS

Head of the Meadow Beach video camera 1 timex 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 timex is a time-averaged image of all frames, smoothing away surface waves and determining the location of persistent wave-breaking (indicative of shallow
