Our vacuum pump was out of order so we had to use our muscles to conduct TSS sampling this friday. 

Observing and collecting data from our mussel gape sensors.

Sam using those muscles to help recirculate sediment upstream.

We’ve got some viaitors at the SAFL outdoor stream lab today.

We prepared mussels for tracking by bedazzling them. Then set them at their initail locations in the stream.
