From: The chemical succession in anoxic lake waters as source of molecular diversity of organic matter
(a) Changes in DOM quality parameters shown as averages of samples from anoxic and oxic compartments of the water column at maximum expansion of anoxia (shortly before mixis, left) and after autumn mixing homogenized these two compartments (right). (b) Relative changes in the areal abundance of carbon species (CH4, DIC, DOC) and Fe before and after autumn circulation (mixis). Values indicate areal content along the whole water column of species during maximum expansion of anoxic waters. Bars indicate the relative elimination of the species (in %). Positive values for DOC indicate net increase in DOC during the time of autumn circulation.
