Collecting data on the Ocean's plankton from around the world.

Secchi App

This project enlists sailors to collect data on the Ocean's plankton from around the world. A scientific study published in 2010 reported that the phytoplankton in the oceans had declined globally by 40% since the 1950s due to climate change. This study provoked controversy among marine scientists however, as some thought they saw contrary results. Part of the controversy stems from a lack of data due to the fact that the oceans are vast and there aren't that many scientists to cover them. This project seeks to overcome that problem through citizen science. More information on this project can be found at: Secchi App
