Figure 3: Weakly negative correlation between char and soot concentrations from sediment samples of Linsley Pond, CT, USA.

Note: Char and soot concentrations were log-transferred. Due to the different factors influencing char and soot deposition in lake sediments (see text for explanations), the (weakly) negative correlation between char and soot mainly reflects climatic factors (wetness and dryness) influencing char and soot production.
