This is an image showing simulated chlorophyll concentrations in the ocean on March 21, 2022. The image has a black background. Regions colored in blue represent areas of low chlorophyll concentration, green are medium, and red areas have high levels. The image has strips of black running through the colored areas from the upper left to the lower right to show PACE’s orbital track around the globe and places across the ocean where it has not scanned.
