Fig. 4: Relationship with summer-time open water fraction (OWF).
From: Upper ocean warming and sea ice reduction in the East Greenland Current from 2003 to 2019
a Correlation map of monthly OWF anomaly with monthly ocean temperature anomaly at 55 m on the shelf (F14, blue diamond) where OWF leads by 1 month, for months when seasonal temperature anomaly was associated with monthly mean practical salinity Sp < 33 at 55 m from the mooring. Thin gray contour mark the area with p-value < 0.05. The cyan box marks the upstream area for which OWF and heat input are calculated and shown in panel (b). b Time series of mean OWF and cumulative mean heat flux in the area upstream of F14 during summer (July–August–September) for years when temperature was greater than the mean temperature between 2003−2009 and when practical salinity Sp < 33 in summer.
