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

3D map illustrated to show the seafloor depths north of Puerto Rico with labels identifying features like ridges and fissures.

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

Time-average image looking at a sandy beach with blurred areas where movement happens over 10 minutes.

Marconi Beach video camera 2 timex 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 timex image, a time-averaged image of all frames which smooths away surface waves and determines the location of persistent wave-breaking (indicative of shallow sandbars). View looks east. [

Time-average image looking at a sandy beach with bright, blurred areas where movement happens over 10 minutes.

Marconi Beach video camera 1 bright 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 “bright” image, 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.

Time-average image looking at a sandy beach with blurred areas tracking the movement of darker objects over 10 minutes.

Marconi Beach video camera 1 dark 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 “dark” image, the darkest pixel values throughout the video, useful for tracking sediment plumes, tracking floating debris, and filtering out breaking waves. View looks northeast. [
