“…Third, elastic deformation of the ocean floor occurs due to changing ocean mass loads (Mitrovica et al, 2001(Mitrovica et al, , 2011, affecting both near-field and far-field ocean heights. Sea level gravitational, rotational and deformational (GRD) fingerprints (Tamisiea et al, 2010;Kim et al, 2019;J. Sun et al, 2022) can be used to calculate the spatial pattern of ocean height changes related to mass changes on land.…”

“…This process can have a significant effect on local sea level near the location of change of continental water source (J. Sun et al., 2022). Second, water added or taken from the oceans moves the center of mass of the Earth and is redistributed on a rotating Earth according to particular spatial patterns (Mitrovica et al., 2001; Tamisiea et al., 2010) and affects sea level in the far‐field.…”

Space gravity missions have enabled the quantification of the mass component of sea‐level rise over the past two decades. Barystatic sea‐level rise is predominantly driven by melting polar ice sheets and mountain glaciers. However, continental hydrological processes also contribute to global sea level change at significant magnitudes. We show that for most coastal areas in low‐to‐mid latitudes, up to half of manometric sea‐level rise is due to changes in water storage in ice‐free continental regions. At other locations the direct attraction effect of anthropogenic pumping of groundwater over the duration of the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (GRACE‐FO) mission offsets sea‐level rise from ice sheet and glacier melt. If these trends in continental hydrological storage were to slow or stop, these regions would experience greatly accelerated sea‐level rise, posing a risk to coastal settlements and infrastructure, however, for most coastal communities current rates of sea‐level rise would be significantly reduced.

Space gravity missions have enabled the quantification of ocean mass increase over the past two decades due to exchanges between continents and oceans. Globally, non-steric sea level rise is predominantly driven by melting polar ice sheets and mountain glaciers. However, continental hydrological processes also contribute to sea level change at significant magnitudes. We show that for most coastal areas in low-to-mid latitudes, up to half of local non-steric sea level rise is due to changes in water storage in ice-free continental regions. At other locations the direct attraction effect of anthropogenic pumping of groundwater over the duration of the GRACE and GRACE-FO mission offsets sea level rise from ice sheet and glacier melt. If these trends in continental hydrological storage were to slow or stop, these regions would experience greatly accelerated sea-level rise, posing a risk to coastal settlements and infrastructure, however, sea level rise elsewhere would be reduced.
