In El Nino years, huge masses of warm water -- equivalent to about half of the volume of the Mediterranean Sea -- slosh east across the Pacific Ocean towards South America. While this warm water changes storm systems in the atmosphere, it also has an impact below the ocean's surface. These impacts, which researchers can visualize with satellite data, can ripple...
