UV or not to UV?

As the days roll past and 15N sampling dates come and go it is easy to forget that the channel experiment stops for no one! Running for almost a month now, the tiles in the experimental channels are beginning to show signs of life. The first biomass sampling of the tiles in our light experiment were collected yesterday and Lyndsie and I spent the day scrubbing tiles in the name of science!

Each channel gets one piece of UV blocking and one piece of transparent plastic, alternating which is up and down stream.

The warmer channels are starting to fill up with all sorts of biomass while the cooler temperature channels show little colonization.

Lyndsie is always hard at work and decided to check the temperatures under our UV plastic to see if they are acting like little green houses facilitating more growth. Good thinkin'!
