Excuse me, flow?

This is a picture of the flume set-up in the lab. I will re-post a more clear picture when I remember to bring my camera to the lab. The tall black tube sticking up is a velocimeter, which measures the velocity of water flow without interfering with the particles moving through the flow, by triangulating some sort of beam that sends back to the computer. The flume has salt water on the inside chamber, with a turbine to make the water flow. The outside is filled with fresh water that regulates the temperature of the inside part. We hooked up the camera today to film our little barnacles! David, Quincy, Brandon and I all stared mesmerized at the screen watching these little barnacles hold out their appendages to catch some plankton. So cool. Our proposals are due this Friday, so I'm going to get writing!
The next photo is a view from where the camera is mounted, looking onto where the barnacles are.
