Argo floats, monitoring ocean health, dissolved oxygen, chlorophyll a

Students will compare dissolved oxygen and chlorophyll a data collected at 3 different locations by Argo floats. Students will discuss the relationship between Chlorophyll A (phytoplankton) and oxygen in the sea, and discuss how the information would be useful in determining ocean health.
