Winter Sampling

A bit of ice on Mendota doesn’t keep the McMahon Lab from getting samples! Robin and Patrick have been collecting bacteria throughout the winter. This involves driving an ATV (or pulling a sled) out to the middle of Mendota, drilling a hole in the ice, and keeping the equipment from freezing. With the water so cold, it may seem unlikely that microbes are still thriving in the lake – but they are! Some of the algae blooms can be seen as brown or pink patches in the ice.

Winter sampling is fun in its own way, but as the ice begins to thaw, we’re looking forward to warm days out on the boat.
