In this mini lesson, students explore the relationship of chlorophyll and solar radiation by analyzing line graphs from the North Atlantic during 2016-2018.

Students identify patterns in chlorophyll concentration data to formulate their explanations of phytoplankton distribution. 

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.

This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.
