Small features, big science! 🌊 In a new NASA-led study, data from the SWOT satellite reveals how small ocean features, some just a mile across, may have larger impacts on the movement of nutrients and heat than previously thought. Too small to see well with previous satellites but too large to see in their entirety with ship-based instruments, these relatively small ocean features fall into a category known as the submesoscale. The SWOT satellite, a joint effort between NASA and CNES, can obser
