Secchi App

Main Project Information
Goal Help study marine phytoplankton.
Task Build a Secchi Disk and measure water turbidity.
Where Global, anywhere on the planet

Join seafarers in the global scientific experiment to study marine phytoplankton.

The phytoplankton underpin the marine food chain, so we need to know as much about them as possible. To participate in this project, you'll need to create a Secchi Disk, a tool that measures water turbidity, and use the free iPhone or Android ‘Secchi’ application.

You can take a Secchi Disk reading as often as you wish, every day, once a week, twice a month, or just occasionally. The data you collect will help scientists around the world to understand the phytoplankton.

Join in and help make this the world’s largest public marine biological study.

How to Join

Obtain the free iOS or Android Secchi App, construct a Secchi Disk, and begin recording data.
