GOES-16 ABI captured soliton waves beneath the ocean surface northeast of northern South America in the tropical Atlantic. Below is a GeoColor image from 9 September 2021 at 12:00:22 UTC from GOES-16 ABI. In the image, the soliton waves appear as dark linear segments oriented southeast to northwest and are regularly separated approximately 150 km. A loop of the GeoColor imagery shows the waves propagating to the northeast; please see loop here: https://rammb.cira.colostate.edu/ramsdis/online/loop.asp?data_folder=loop_of_the_day/goes-16/20210910000000&number_of_images_to_display=150&loop_speed_ms=100.
