Internal Tides, or Internal Waves

Internal tides, or internal waves, can reach hundreds of feet underneath the ocean surface, but might only be a few inches high on the surface. Even though they’re underwater, #NASA​ can see these tides from satellites. They provide #science​ oceanographers with a unique way to map and study the much larger internal water motion.
