Summary: Biogenic silica profiles in varved sediments from northern Lake Malawi (Nyasa), East Africa, span the past 700 yr and reflect
past primary productivity in the overlying waters. On a centennial scale this has been influenced by lake level and a consequent
shift in the location of high diatom productivity within the lake basin. Primary production was higher during the Little
Ice Age, an arid period from about A.D. 1570 to 1850, when lake level was about 120 m lower than during the previous three
centuries or the past 150 yr.
