Meltwater pulse 1A was a period of rapid deglacialization that took place 14.7-14.2 thousand years ago.[1]. 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.[2] The source of the meltwater is often believed to be a collapsing ice sheet probably in Antarctica[2] Meltwater pulse 1A occurred during the end of the last glacial period.
