Titre : Ratio Fluorescence Line Height vs. Chlorophyll
Description : (La description de cette image n'existe qu'en anglais)
Satellites provides the unprecedented ability to measure chlorophyll fluorescence, which gives insight into the health of phytoplankton in the ocean. When phytoplankton are under stress, they no longer photosynthesize and begin to emit absorbed sunlight as fluorescence. This image taken over the Arabian Sea shows a ratio of chlorophyll to fluorescence which provides information on the degree of photosynthetic activity occurring (blue shows higher photosynthesis).
