We’re just testing a bunch of instruments that we have. She’s doing a dye concentration experiment for just the diffusion of the dye and where the flows spread contaminants around this area. You can definitely use hydrodynamic models for that. We’re just trying to show the practical applications of what coastal engineers would do, how they use these instruments, and what types of measurements they take. Well, at different depths in the lake there’s going to be different currents in the water. So, we’re going down every half meter We wanted to, kind of, check out the different velocity profiles in the lake as it got deeper. If you look over on the shoreline, there’s two different types of beaches, right next to each other. Science would be dead in the water without duct tape. Everything needs duct tape. A lot of the course is just letting everybody else in the class kind of get familiar with different survey methods, and learn how things don’t go exactly perfect in the field when you plan that they will, and, once you’re out two miles on the lake, you know, it’s not easy to just come back and get your stuff, so… That’s a big lesson we’ve been learning.
