Secchi Disk May news update now on FB facebook.com/secchidisk. Funding news and a fundraising appeal.

12 years ago I started the SecchiDisk.org study to engage seafarers to collect data on the phytoplankton. Today, we start year 13. It is now the longest-running and most spatially, extensive marine citizen science study of the sea's most important life. Join everyone taking part and collect data for the Study. This is also a birthday appeal. The Study's independent growth has been achieved without any institutional funding. If you are a CEO or director of a company and you feel aligned with our goals in wanting to engage citizens in environmental science and life-long learning, please get in touch. Together, we can go so much further.

Today, it's the secchidisk.org study's 12 birthday. The world's longest running and most spatially extensive citizen science study of the phytoplankton. If you love the ocean and got to sea, JOIN IN as we begin year 13. facebook.com/secchidisk #MyXAnniversary
