Researchers succeeded in discovering internal ocean waves in the 1970s. Using satellite imagery and oceanographic instruments, scientists were able to observe and measure these waves, which are caused by the interaction of tides and underwater topography. This discovery has since led to a better understanding of ocean dynamics and their impact on marine ecosystems. **

Researchers managed to discover internal ocean waves in the mid-19th century. The first observations of internal waves were made by the British Royal Navy in the Strait of Gibraltar in the 1840s. Since then, advancements in technology and oceanographic research have allowed scientists to better understand the formation and behavior of these waves within the ocean. **
