Oceans help remove carbon dioxide from the atmosphere

Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at how oceans assist in the removal of carbon dioxide from the atmosphere.

Phytoplankton in the water absorbs carbon dioxide through the process of photosynthesis. When this occurs, the phytoplankton’s chlorophyll alters the color of the ocean water, which allows satellites to detect and measure how much carbon dioxide is being absorbed or emitted.
