Abstract:

In this dataset we present high resolution Pb isotope records from the Mackenzie Delta area and the Amundsen Gulf. Here we present the authigenic as well as the detrital isotopic composition. With both components it is possible to give an accurate interpretation of meltwater runoff into the Arctic.

Keyword(s):

Deglaciation; Lake Agassiz; Lead isotopes; Mackenzie; Meltwater; Meltwater pulse; Pb isotopes; Younger Dryas
