Fig. 2: Indicators of a mode shift beneath Filchner Ice Shelf.

From: Observed interannual changes beneath Filchner-Ronne Ice Shelf linked to large-scale atmospheric circulation

Fig. 2

Time series of (a) ice shelf basal melt rates near FNE1, and (b) ocean conservative temperature at FNE1. c Source water salinities observed at each ice shelf mooring, indicating the Ronne (orange) and Berkner (green) HSSW regimes, and (d) 15-day low-pass filtered daily SFRs in front of Ronne Ice Shelf in comparison with the long-term average (green dashed line). e, f CTD sections of ocean conservative temperature at locations indicated in Fig. 1a along the Filchner Ice Shelf front for February 2017/2018. Thick black ticks along the y-axis in (b) indicate the depth of the temperature sensors at FNE1. Black −2.00 °C and −2.25 °C temperature contours in (a, e, & f) delineate the presence of ISW. Red horizontal lines in (a) and (d) show time-averaged values over shorter periods of each time series.
