Seafarers are being encouraged to take part in a unique global study, using a mobile phone app to record the effects of climate change.
The public science project will measure the amount of phytoplankton, minute organisms at the very start of the marine food chain, currently residing in the world's oceans.
Scientists fear the population of the microscopic beings is in decline due to rising sea temperatures and, if true, that could have consequences for every aspect of marine life.
The project is being spearheaded by Plymouth University's Marine Institute, which hopes to build a map of the oceans that charts the seasonal and annual changes of phytoplankton from now and into the future.
Plankton biologist Dr Richard Kirby, who is leading the study, said: "As the phytoplankton live at the surface of the sea they are being affected by rising sea temperatures due to climate change. A scientific paper published last year suggested the ocean's plankton population had declined by as much as 40 per cent since 1950. Like all marine creatures, phytoplankton have a preferred optimum sea temperature no matter where they are in the world and we need to know more about how they are changing in order to understand the effects on the ocean's biology."
To check the levels of phytoplankton in our oceans, marine experts have developed a free smart phone app for sailors and fishermen to use wherever they are in the world.
Because the phytoplankton each thinner than a strand of human hair exist at the sea's surface, mariners can carry out a simple experiment using an easy to make 'Secchi Disk'.
Attached to a measuring tape, the Secchi Disk is lowered over the side of a boat and the depth at which it disappears from sight estimates the amount of phytoplankton in the sea. This depth can then be uploaded to a database using the Secchi app.
Dr Kirby added: "The Secchi Disks are still used by marine scientists to s
