Ocean life
Chlorophyll-a in the surface ocean, the pigment of phytoplankton, which shows where marine life is concentrated.
What it shows
Chlorophyll-a in the surface ocean, the pigment of phytoplankton, which shows where marine life is concentrated. Upwelling zones and spring blooms stand out against the nearly empty ocean gyres. PACE is the newest sensor; VIIRS and Aqua cover dates before PACE began.
Where the data comes from
NASA Ocean Biology DAAC via NASA EOSDIS GIBS: PACE OCI, VIIRS NOAA-20 and MODIS Aqua chlorophyll-a; daily.
