- Small currents, big impact: Satellite breakthrough reveals hidden ocean forceson May 30, 2025 at 4:39 pm
While scientists have long studied currents of large eddies, the smaller ones -- called submesoscale eddies -- are notoriously difficult to detect. These currents, which range from several kilometers to 100 kilometers wide, have been the 'missing pieces' of the ocean's puzzle -- until now. Using data from the new Surface Water and Ocean Topography (SWOT) satellite, scientists finally got a clear view of these hard-to-see currents, and they are a lot stronger than anyone thought.

Thanks to new research, scientists believe that these creatures are 14 million years older than previously thought. The new age -- dating back to 346 million years ago -- adds to the significance of the find because it places the specimens in a mysterious hole in the fossil record called Romer's Gap.
