Ocean Chlorophyll Concentrations (Northern Hemisphere)

This image shows season-long composites of ocean chlorophyll concentrations derived from visible radiometric measurements made by the VIIRS instrument on Suomi NPP. The date ranges are included. This false-colored image makes the data stand out. The purple and blue colors represent lower chlorophyll concentrations. The oranges and reds represent higher chlorophyll concentrations. These differences in color indicate areas with lesser or greater phytoplankton biomass. Credit: NASA/Suomi NPP/Norman Kuring
