Investigations on catchment, vegetation, and lake surface sediments to identify end members for reconstructing past lacustrine primary productivity (LPP) in the Tso Moriri Lake.

Data reveal limitations of using isotopic and C/N data on bulk organics as indicators of LPP.

LPP in recent times is not much higher than during the early Holocene warm period ruling out the possibility of large carbon sequestration in high altitude oligotrophic lakes.
