The Secchi Disk Foundation

We help sailors study the sea. The Secchi Disk Foundation runs the Secchi Disk study (, the world's largest citizen science study by seafarers of the marine phytoplankton - the microscopic plant-like algae that begin the marine food chain.

Do you love the ocean and its marine life? Would you like to help inspire others and help increase our knowledge? If so, support the Secchi Disk Foundation with a donation.

Any amount you give will help us to engage people of all ages around the world in fun, hands-on marine science to help us collect essential data and better understand ocean life and the challenges it faces. The following video explains how.
