00:00This is a very small plankton net. It's got a very small mesh size on so that we can capture

00:10the very smallest plankton, the phytoplankton. This is being used as a traditional method

00:16for many, many years. This is something I do every week.

00:20It's going down quite far. It is going down quite far, so we're here

00:25about 50 metres. It's just a question of very gently bringing

00:29it back up. It just sifts through the water and concentrates

00:33the plankton, which we can then pop in a bottle and take back to the laboratory to have a

00:41look in the microscope. So here we go. We just pop it in there.

00:50It's hard to imagine, just looking at it, that there is that much life.

00:53It is, yes. In a single drop of water, there are thousands of individual plankton.
