Sea-level fingerprinting as a direct test for the source of global meltwater pulse IA.

Clark, P. U. and Mitrovica, J. X. and Milne, G. A. and Tamisiea, M. (2002) 'Sea-level fingerprinting as a direct test for the source of global meltwater pulse IA.', Science., 295 (5564). pp. 2438-2441.


The ice reservoir that served as the source for the meltwater pulse IA remains enigmatic and controversial. We show that each of the melting scenarios that have been proposed for the event produces a distinct variation, or fingerprint, in the global distribution of meltwater. We compare sea-level fingerprints associated with various melting scenarios to existing sea-level records from Barbados and the Sunda Shelf and conclude that the southern Laurentide Ice Sheet could not have been the sole source of the meltwater pulse, whereas a substantial contribution from the Antarctic Ice Sheet is consistent with these records.
