What we do

The Secchi Disk Foundation engages people of all ages around the world with fun, hands on marine science to inspire and educate while increasing our knowledge of the sea.

How we do it

We run the Secchi Disk study, the world's largest citizen science study of the phytoplankton. Today, these tiny, sea surface, plant-like algae that start the marine food chain are altering in their abundance and distribution due to climate change. By supporting the Secchi Disk Foundation you can help us learn more about these changes. Read the study's first paper in PLOS ONE.
