Fig. 3: Signal-to-Noise Ratio (SNR) in sea surface salinity (SSS) and δ18Osw.

Fig. 3

| Panels a, c show the SNR in SSS relative to unforced intraseasonal and interannual variability, respectively. While panels b, d provide the corresponding SNR values for δ18Osw. This figure offers a visual representation of the SNRs in SSS and δ18Osw attributed to ice-sheet freshwater discharge (IFD). SNRs were calculated using the forced response of SSS and δ18Osw to IFD from 2076 CE to 2085 CE (FWF-GHG585) as the signal. The noise was determined using 1σ of the monthly mean and annual mean from the control experiment. Orange stippling denotes the region where IFD force is applied.
