Students will analyze the monthly seasonal chlorophyll concentration images in our global oceans for the four different months of 2024, and then answer the following questions.

Students will analyze the mapped plot of the historic Ocean Chlorophyll Concentrations at key locations around the world for the period of 1998-2018.

In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.

This lesson is taken from NASA's Phytopia: Discovery of the Marine Ecosystem written in partnership with Bigelow Laboratory for Ocean Science with funding from the National Science Foundation.

Meet Clarissa Anderson, a biological oceanographer who is currently serving as the director of Southern California Coastal Ocean Observing System at Scripps Institution of Oceanography. She is working with NASA to pursuing solutions regarding harmful algal blooms on California's Coast.

This mini lesson engages students by watching a NASA video related to seasonal chlorophyll concentration as it relates to net radiation using NASA's Aqua satellite. Students will examine the model and answer the questions.

Explore and connect to the GLOBE Water Quality protocol bundle. 

Students review the NASA video showing biosphere data over the North Atlantic Ocean as a time series animation displaying a decade of phytoplankton blooms and answer questions.

Students identify patterns and describe the relationship between chlorophyll concentration and incoming shortwave radiation. 

Explore the biosphere and why it is important.
