What’s green, microscopic, and makes ½ our oxygen?

What’s green, microscopic, and makes half of the oxygen we breathe? Phytoplankton, the tiny algae at the base of the food chain, that’s what!

Measurements of chlorophyll — the green pigment that enables plants and algae to photosynthesize — provide an estimate of how much phytoplankton are in our coastal waters.

In this third edition of Mike’s Field Notes, Staff Scientist Mike Doan shares what he sees when he looks at our Continuous Monitoring Station’s most recent chlorophyll data. You can watch the three-minute video below.

In case you missed them, here are links to the first two videos of Mike’s Field Notes:
