Example of sea-level fingerprints for Antarctic (lower panel) and Greenland (upper panel) meltwater. Meltwater produced from each ice sheet creates a different magnitude of sea level depending on position relative to the source region. The value plotted in each panel is the dimensionless quantity \((\Delta \zeta_{{{\text{rsl}}}} (\phi ) - \Delta \zeta_{{{\text{gmsl}}}} (\phi ))/\Delta \zeta_{{{\text{gmsl}}}} (\phi )\), where Δζgmsl (ϕ) is global mean sea level added to the oceans over a short (effectively instantaneous) time interval. Contours are in increments of 0.25 for positive and 1.0 for negative values. The far field signal is uniquely characteristic of the source region
