WebMar 11, 2016 · Cryoconite casserole samples were collected using sterile spatulas and were spread evenly onto microscopy slides. The structure and composition of the cryoconite sediment was observed with an Olympus BX-51 optical and fluorescent microscope, following previously described methods (Takeuchi et al., 2010. Web[1] The cryoconite holes of the McMurdo Dry Valleys are simple, closed biogeochemical systems involving water, ice, mineral and organic debris, which serve as ecosystems for consortia of microorganisms. This study is the first to document the seasonal and annual chemical evolution of solutes in cryoconite holes. Samples of glacier ice, frozen
