How internal waves transport energy thousands of miles across the ocean

Both winds and tides inject energy into the ocean. Much of that energy is then transported up to thousands of miles by internal waves: large-scale underwater waves that can travel between ocean basins. Quantifying the amount of energy transported by internal waves and assessing their dynamics are difficult given their location and scale. Still, the question is important because internal wave dynamics interact with the global climate and underwater ecosystems by influencing currents, ocean mixing, and more.
