PROJECT INFO

Phytoplankton are microscopic plant-like organisms that are at the base of the food web and support all life at sea. They are so abundant that they account for about 50% of the oxygen produced on Earth and sequester carbon which then acts as a natural carbon sink. Recent research suggests that phytoplankton have declined by 40% globally between 1960 and 2010 due to climate change.
The Secchi Disk study was launched in 2013. It invites citizen scientists to increase data collection on the current state of marine phytoplankton by just using a simple white disk called a Secchi Disk.
WHAT IS IT ABOUT?
By participating in the Secchi Disk study during our polar travels, we help close much needed data gaps. This helps scientists better understand how phytoplankton in the polar regions are reacting to environmental changes and what implications this will have for the wider polar ecosystem: from algae to seabirds, seals and whales.
HOW CAN WE HELP?
SEASON UPDATE
PROJECT IMPACT
Secchi Disk data collected by citizen scientists and guides on expedition cruises play a key role in helping organisations like the National Oceanic and Atmospheric Administration (NOAA) and other academics study global changes in phytoplankton.
PROJECT PARTNERS
The Secchi Disk study is an independent study run by the Secchi Disk Foundation, a UK-registered charity.
