The ‘classic’ and ‘improved chromatography’ GDGT methods are used in Danube sediments. Improved isomer separation helps to disentangle sources of brGDGTs in river sediment. BrGDGT-derived MAT and pH follow the actual values from headwaters to the delta. BrGDGT signal into the Black Sea is greatly influenced by inputs from the lower basin.
