Abstract
We studied the distribution of glycerol dialkyl glycerol tetraethers (GDGTs) in suspended particulate
matter from the water column of Lake Tanganyika (East Africa), where sediment studies had shown
the applicability of the TEX86 proxy for reconstructing surface lake water temperature. GDGTs, in particular
crenarchaeol, showed maximum abundance within the suboxic zone (100–180 m),
