You can participate in this project by making a Secchi Disk and using the free to download iPhone or Android ‘Secchi’ application.
Join in and make this the World’s largest, ongoing Citizen Science marine biological study.
"You don’t need a network connection to use Secchi. Secchi stores all the data until you get a mobile signal when it will ask you if you want to submit your data now, or wait until later."

The marine phytoplankton account for approximately 50% of all photosynthesis on Earth and, through the plankton food web that they support, they both underpin the marine food chain and play a central role in the global carbon cycle strongly influencing the Earth’s climate.
Living at the surface of the sea the phytoplankton are particularly sensitive to changes in sea surface temperature. A recent study of global phytoplankton abundance over the last century concluded that global phytoplankton concentrations have declined due to rising sea surface temperatures as a consequence of current climate change.
We need to know much more about these changes and you can help by making a simple piece of scientific equipment called a Secchi Disk and using the Secchi App.
