摘要

在最后一次冰消期，陆地上冰盖融水事件的证据非常罕见。然而，它们是对海洋记录的宝贵补充，这些记录表明，巨大的冰盖融化水脉冲流入东北太平洋，称为Siku事件。在这里，我们描述了最后一次消冰期早期喀斯特化冰川外溢平原上的陆地科迪勒冰盖融水档案，并确定了其年代，显示了大约2万至1.7万年前的半连续融水事件。

Semi-continuous release of Cordilleran Ice Sheet meltwater between 20,000 and 17,000 years ago

Terrestrial evidence of ice-sheet meltwater events during the last deglaciation are exceptionally rare. However, they are a valuable complement to marine records that suggest immense ice-sheet meltwater pulses discharging into the Northeast Pacific, termed Siku events. Here we describe and date a terrestrial Cordilleran Ice Sheet meltwater archive in a karstified glacial outwash plain during the early last deglaciation, showing semi-continuous meltwater events between about 20,000 and 17,000 years ago.
