Glycerol dialkyl glycerol tetraethers (GDGT) are membrane lipids that have become a useful tool in palaeoclimatology, the GDGT-based proxies have been applied to reconstruct paleoclimatic variation in marine, lake, peat bog and soils environments due to their sensitivity to environmental parameters, such as temperature and pH. Several calibrations based on the distribution of GDGTs in lake surface sediments have been established in global and regional lakes, they have been widely utilized to reconstructed environmental variation in paleolimnology. Compare to the ubiquitous occurrence of GDGTs in lake sediments, GDGTs analysis of the lake water column is limited, however, increasing evidence has demonstrated that the contribution of GDGTs from the lake water column to lake sediments is not negligible. It is thus vital to address the relationship between the distribution pattern of aquatic origin GDGTs within the lake water column and environmental factors before we apply the GDGT-based proxies in lake environments to reconstruct paleoclimate. In this paper, we first introduced the GDGTs distribution in the lake water column, to see whether there was a correlation between GDGTs distribution and water depth in terms of the GDGT concentration and the fractional abundance of individual GDGTs. We also reviewed the biological source of the archaea derived isoGDGTs and bacteria-derived brGDGTs of the lake water column, respectively. Further, we found that temperature was still one of the main controlling environmental factors that influence the fractional abundance of GDGTs and other related GDGT-based proxies in the lake water column, however, it is worth noting that the coupling relationship between temperature, water depth and dissolved oxygen in the lake could complicate the GDGTs distribution in the water column.
