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.
作为融水脉冲IA源头的冰库仍然是个谜，且存在争议。我们表明，针对该事件提出的每种融化情景都会在全球融水分布中产生独特的变化或指纹特征。我们将与各种融化情景相关的海平面指纹特征与来自巴巴多斯和巽他陆架的现有海平面记录进行比较，得出结论：劳伦泰德冰盖南部不可能是融水脉冲的唯一来源，而南极冰盖的大量贡献与这些记录相符。
