What happens in the sea during a solar eclipse?
On July 20th, 1963, three scientists sat on a research ship 200 miles south of Woods Hole, MA, waiting for something remarkable. They were nearly 4000m above the seafloor, and using sonar, they could ‘see’ a line of creatures resting in the deep. By this time, biologists were beginning to unravel the mystery of this ‘false bottom’–a layer in the ocean that looks the the sea floor on sonar but isn’t–which covered much of the ocean. This false bottom rises in up at night and sinks down during the day. This rising and falling is in fact caused by the largest migration of animal on Earth–everything from fish, shrimp and jellyfish, moving hundreds of meters in unison up and down each day. But how and why these animals rose in fell in the ocean wasn’t clear. As the scientists watched their instruments, the light began to fade. Not from the setting sun, but from something else. click here to read the story 13:27
