Meltwater pulse 1A was a period of rapid deglaicialization about 14,000 years ago. During this pulse the sea level rose by about 25 m in some parts of the northern hemisphere, over a period of less than 500 years.[1] The source of the meltwater is believed to be a collapsing ice shelf probably either in Antarctica[1], or the British-Irish Ice Shelf (BIIS).[2] Meltwater pulse 1A occurred during the end of the last glacial period.
