(Right) High-resolution image of a cross-section of the sediment including the sediment water interface to ~25 cm below surface from a site in the central basin of Lake Erie. Visible are various strata of the sediment, including a thin periphyton surface, quagga mussels, redox layers, and macroinvertebrate organisms in their tubes and burrows.
