Saturday, January 25, 2020

Meet Academy Scientist Mariena Hurley, who studies diatoms.

Diatoms are microscopic aquatic algae with cell wall made of silica that gives each species unique ornamentation. They serve as a very important food source for as animals like fish, whales, and zooplankton and also produce roughly 40% of the oxygen humans breathe. Diatoms also serve as water quality indicators to help maintain the health of our water systems.

Learn how to identify the diverse world of diatoms under a microscope. Gain first-hand experience determining water quality based on the species you find.
