NASA | Carbon in the Ocean

Phytoplankton are crucial for oxygen production and the marine food chain. Understanding their response to climate change is vital. NASA has been studying ocean biology using satellites, aircraft, and ships for over 30 years, providing valuable data to analyze oceanic climate change over decades.

What is the primary role of phytoplankton in the marine ecosystem?

• They are the top predators.

• They produce over half of the oxygen we breathe.

• They are responsible for ocean currents.

• They decompose organic matter.

Why is it crucial to study the response of phytoplankton to climate forces?

• Because they are a fundamental part of the marine food chain.

• Because they are responsible for all marine life.

• Because they can predict weather patterns.

• Because they are the only source of food for humans.

How long has NASA been studying the biology of our oceans?

• For over 7 decades.

• For over 1 decade.

• For over 3 decades.

• For over 5 decades.

What methods has NASA used to study ocean biology?

• Satellites, aircraft, and ships.

• Only ships.

• Only aircraft.

• Only satellites.

What does the combined data set from NASA's studies provide?

• A short-term analysis of oceanic changes.

• An unprecedented opportunity to study oceanic climate change over decades.

• A limited view of oceanic climate change.

• A detailed study of terrestrial climate change.
