NASA is conducting a study of the world’s largest phytoplankton bloom in the North Atlantic to see how the tiny sea critters influence the climate in every season.
FACTS FOR PRELIMS
About the Mission
About half the carbon dioxide emitted into Earth’s atmosphere each year ends up in the ocean, and plankton absorbs a lot of it. The North Atlantic Aerosols and Marine Ecosystems Study (NAAMES) studies the world’s largest plankton bloom and how it gives rise to small organic particles that leave the ocean and end up in the atmosphere, ultimately influencing clouds and climate.
The mission recently began its fourth and final deployment, which will study how phytoplanktons give rise to small organic particles that leave the ocean and end up in the atmosphere, ultimately influencing clouds and climate. It is the first research mission to conduct an integrated study of all four distinct phases of the world’s largest phytoplankton bloom.
Rates of phytoplankton accumulation are critical for understanding the ocean conditions that lead to phytoplankton growth and its timing, a key to unlocking the environmental drivers and controls of biological dynamics. By observing the collective data provided by NASA satellites, meteorological balloons etc scientists are able to not only understand the current state of the atmosphere but also how it is evolving over time.
NOTE4STUDENTS-Satellites such as CALIPSO, a joint NASA and CNES mission, also help to study the ocean and the atmosphere – from the depths of the phytoplankton bloom, to the clouds and atmospheric particles in the sky above.
