Researchers Ask For Help In Global Plankton Survey

#MarineScience - Researchers at a UK university are hoping to enlist seafarers to help conduct one of the world's biggest studies of ocean plankton.

BBC News reports on the project by the Marine Institute at Plymouth University, which hopes to encourage fishermen and sailors alike to take part in its survey in Britain's coastal waters - including the Irish Sea - and far beyond.

Anyone participating in the study must drop off the side of their vessel an apparatus called a Secchi disk - a 30cm-wide flat white disk attached to a tape measure or a rope, and weighted from below by a small 200g weight.

When the disk disappears from view, that level is known as the Secchi Depth, which measures the turbidity of the water, which in turn is influenced by the amount of the microscopic marine wildlife in the water column.

Seafarers are being asked to record the Secchi Depth and upload to researchers via a mobile app for iOS and Android devices in order to build a complete picture of plankton activity in the world's oceans.

"If we can just get a small percentage of the global population of sailors involved, we can generate a database that will help us understand how life in the oceans is changing," said project leader Dr Richard Kirby.

"It would help us learn much more about these important organisms at a crucial time when their habitat is altering due to climate change."

Coronavirus (COVID-19): Irish Sailing & Boating

Since restrictions began in March 2020, the Government is preparing for a 'controlled and gradual return to sport' and the 2020 sailing fixtures are being tentatively redrafted by yacht clubs, rowing clubs angling and diving clubs across Ireland as the country enters a new phase in dealing with the Coronavirus.

are a close contact of a confirmed case of coronavirus

have returned to Ireland from another country

You need to restrict your movements for at least 14 days.

But if the person you live with has had a test and it is negative, you don't need to wait 14 days. You should still follow the advice for everyone - stay at home as much as possible.

Close contact

This is only a guide but close contact can mean:

spending more than 15 minutes of face-to-face contact within 2 metres of an infected person
