“Well, that was an adventure!” says Aaron O’Connell, a UW-Plateville undergraduate, looking down at his bare feet as he steps gingerly across the gravel driveway. In one hand he carries his sodden shoes, and like me, he is covered from head-to-toe in lake grime. We have just spent the last two hours helping Tim Meinke launch a buoy into Sparkling Lake off of Highway 51 in Vilas County.

The buoy itself is an impressive device—substantial in girth, equipped with everything from weather antennae to a pressure sensor that records rainfall. A large solar panel hangs on one side, and the whole contraption is strung with a variety of complex wiring that is well beyond my expertise.

Meinke, a researcher at the Center for Limnology’s Trout Lake Station, is part of the Long-Term Ecological Research project (LTER) and the Global Lake Ecological Observatory Network (GLEON). Sparkling Lake is one of the LTER and GLEON research lakes, so the buoy will spend the summer collecting data on everything from water temperature to wind speed to the amount of oxygen moving in and out of the lake. But getting that buoy in the water is no small feat, which is why Meinke enlisted Aaron, Ben Kranner, a UW-Madison undergraduate, and the CFL’s IT consultant, Mark Gahler, to the cause.
While they anchored and wired the buoy, I did my best to stay out of the way and document the experience. This proved more difficult than I had anticipated, as the team hauled in various ropes and weights, gradually filling the boat with lake debris and slime (or, as we call it in scientific circles, “muck”) from the bottom. My chance to contribute to the effort came when we had to retrieve a smaller buoy from just under the surface. It was anchored by sixty pounds worth of barbells, which I hoisted into the boat, a feat that proved challenging despite my enthusiasm. With Aaron’s help, we managed to haul the buoy and weights into the boat. I was grimy and out of breath, but proud to have been of service. Continue reading
