Short summary

The Atlantic Meridional Overturning Circulation (AMOC) is a key mechanism for large-scale northward heat transport and plays an important role for global climate. Previously, AMOC changes have been inferred from in situ ocean bottom pressure (OBP) observations at single latitudes. We extend the analysis to space-based observations (and the whole North Atlantic) and show on data from the ECCO2 model that AMOC anomalies can be inferred from OBP at a resolution resembling the GRACE gravity mission.
