Baltic Sea Phytoplankton

This image shows a phytoplankton bloom in the Baltic Sea this summer. The phytoplankton act like seed particles in the water, which allows us to see the swirling patterns from currents, wind, and other gradients. When zooming in on the image, there are straight lines showing wakes from boats. This image is really interesting because the phytoplankton allow us to capture otherwise invisible fluid dynamics within the ocean. The image comes from a U.S. geological survey satellite called the Landsat 9. It was captured by Michala Garrison.
