Spatial and temporal variability in sedimentological and geochemical properties of sediments from an anoxic crater lake in West Africa: Implications for paleoenvironmental reconstructions

► New insights into the controls on spatial patterns of modern lake sediments ► Indicates dominant control of depth on geochemistry and sedimentology ► Sediment proxies differ in their relationships with depth. ► These differences need to be considered in the interpretation of downcore records. ► Century scale climate variability dominates the last 2 millennia in West Africa.
