Green and turquoise swirls in the blue ocean south of green and tan Cape St. Francis, South Africa indicate the presence of phytoplankton blooms. Sun glint highlights both surface swells (tiny linear repeating patterns having mostly the same orientation) and internal waves (larger, more widely spaced criss-crossing patterns). Several large ships and their wakes also traverse the ocean pixels. This image was collected by Landsat 8 / OLI on January 24, 2026 at 8:11 UTC.
The #Agulhas Current turbulently interacts with the continental shelf south of #CapeStFrancis leading to phytoplankton blooms (that color the ocean) & internal waves (that become visible by modifying surface smoothness).
