Short summary

In this study, we demonstrated that the composition of sediment organic matter can vary significantly within a single lake, in a close relationship with the spatial patterns of elemental inorganic geochemistry. This results from a combination of different bio-, geo- and physicochemical lake factors, and our results highlight that the potential for large spatial variability across lakes should be considered when studying carbon, nutrient and trace element cycling at lake and global scales.
