GRIP deuterium excess reveals rapid and orbital-scale changes in Greenland moisture origin
The Northern Hemisphere hydrological cycle is a key factor coupling ice sheets, ocean circulation, and polar amplification of climate change. Here we present a Northern Hemisphere deuterium excess profile covering one climatic cycle, constructed with the use of delta(18)O and delta D Greenland Ice C...
