Secchi Disk Project

Richard Kirby, a plankton scientist at Plymouth University, UK, wrote to us recently to about the new Secchi Disk project.  It is a really simple way of measuring plankton abundance with a circular home made disc and graduated line or measuring tape.  It is all about citizen science and we'd encourage every-one to take a look at the web site and help out. After all plankton provide us with about half the oxygen we breath.
