Equipment trials

The first plankton net arrived on Friday so we’ve been in the River Usk this weekend testing out how we’re going to deploy the nets when we’re in Canada. The idea of using a tripod, weighted down with a few rocks, seemed to work well. The water velocity was approximately 0.4 m/s which is probably lower than on the Wind and Peel rivers, but the tripod was pretty stable. 

We had a look afterwards to test out the various microscopes and to see what we'd found. Here's a couple of pics!

Below is a small sliver of uPVC that we had a look at to see what it looked like under the microscope as well.
