Using Video Imagery to Study Wave Dynamics: Tres Palmas

Four video cameras look westward over the coast and the coral reef at Tres Palmas in Rincón, on the west coast of Puerto Rico. Two cameras look out at the horizon and over the ocean for the mid-field view; one camera offers a zoomed-in, far-field view overlooking the reef and out to the island of Desecheo, a U.S. National Wildlife Refuge; and another camera focuses on the beach.
