From: The chemical succession in anoxic lake waters as source of molecular diversity of organic matter
Spatiotemporal oxygen distribution in the two sampled north temperate lakes, Lake Croche (above), and Lake Cromwell (below). Data is acquired using 8–10 continuously measuring probes per lake and monthly profiles (grey dots indicate sampling positions). The black line separates the well-mixed epilimnion from the stagnant hypolimnion. The red line demarks the oxygen-free waters of the hypolimnion (threshold: 0.3 mg L−1, 8 µM).
