Some of this water makes a shortcut and recirculates [...] the western Fram Strait on timescales of several months while the rest enters the Arctic Ocean and follows a cyclonic circulation for years to decades. The AWI long-term observations in Fram Strait have [...] Fram Strait / West Spitsbergen current long-term observations Atlantic Water is the main oceanic source of heat, salt, and nutrients of the Arctic Ocean. It enters the Arctic Ocean through the Barents

We observed Atlantic water warming in Fram Strait and this water is likely to affect the (presently) stable North East Greenland ice stream (NEGIS)
