Surface waters are densified through cooling [...] storing) Beaufort Gyre, and the Transpolar Drift, which drives the freshwater towards Greenland and Fram Strait from where it is eventually exported to the subpolar North Atlantic. The Arctic freshwater [...] contributes to a destabilization of the Greenland ice streams. We observed Atlantic water warming in Fram Strait and this water is likely to affect the (presently) stable North East Greenland ice stream (NEGIS)
