As seen on #Cosmos: Most life in the ocean does not have fins or flippers. Single celled organisms called phytoplankton far outnumber the sum of all the marine organisms most of us think of first. While phytoplankton individually are largely invisible to the naked eye, their total effects can be seen from space. There are many trillions of phytoplankton in the sea, and together they convert huge quantities of carbon dioxide (CO2) into living matter. In that process they release a major percentage of the world's oxygen into the atmosphere. These life processes help regulate the planet's overall climate and habitability and are a bellwether of planetary health.
NASA research using satellite measurements of phytoplankton has opened the door to global observations of these tiny life forms as a group, essentially helping scientists put a finger on the living pulse of the oceans, the rhythm of life upon which we all depend.

This data visualization comes from the MODIS instrument on NASA’s AQUA spacecraft. Here we see a measure of global chlorophyll concentrations, derived from data collected between July 1, 2002, and December 31, 2004. This visualization has a 4-kilometer measure of resolution.
