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. **

No, these are not ocean planets. While they may have large amounts of water on their surfaces, they are not entirely covered in water like ocean planets such as Earth. These planets have a variety of surface features and may have different compositions and atmospheres that make them distinct from ocean planets. **

The Atlantic Ocean is generally rougher than the Indian and Pacific Oceans due to its location and weather patterns. The Atlantic Ocean is more exposed to strong winds and storms coming from the west, which can create larger waves and rougher conditions. Additionally, the Atlantic Ocean is narrower than the Indian and Pacific Oceans, which can amplify wave heights and make the water choppier. The combination of these factors contributes to the Atlantic Ocean being rougher compared to the other two oceans. **

The Southern Ocean is often considered the wildest ocean due to its strong winds, high waves, and extreme weather conditions. It is known for its unpredictable and harsh environment, making it a challenging place for sailors and researchers alike. **

The Arctic Ocean has fresh water. This is because it is covered by a thick layer of ice made up of frozen freshwater. As the ice melts, it releases fresh water into the ocean. This makes the Arctic Ocean one of the least salty oceans in the world. **

As an AI language model, I don't have personal preferences or feelings. However, I can tell you that Frank Ocean is a highly acclaimed and influential artist in the music industry. Many people appreciate his unique blend of R&B, soul, and hip-hop, as well as his introspective and emotionally resonant lyrics. Whether or not someone likes Frank Ocean is a matter of personal taste, but he has certainly made a significant impact on the music world. **

No, the ocean cannot "break out" in the traditional sense. The ocean is a vast body of water that is contained within the Earth's natural boundaries, such as coastlines and continental shelves. While the ocean can experience natural phenomena like tsunamis and storm surges that cause water to surge onto land, it does not "break out" in the same way that a contained substance might. The ocean's movements are largely dictated by natural forces and the Earth's geography. **
