     abstract = "{Accurate quantification of regional ocean mass changes is crucial for
        coastal communities to formulate effective management
        strategies. The regional ocean mass budget comprises the
        barystatic component driven by terrestrial water and ice mass
        changes, and ocean mass redistribution resulting from non-tidal
        oceanic and atmospheric (Nt-OcnAtm), the latter being zero in
        the global mean. This study investigates the influence of the
        Nt-OcnAtm component on the ocean mass budget across 19 critical
        marginal seas spanning the period from 2005 to 2015, utilizing
        an improved ocean mass budget equation. Our analyses suggest
        that 14 regions close the ocean mass budget within 1-sigma
        uncertainty, while five regions close within 1.65-sigma
        uncertainty. Then, the findings indicate that the Nt-OcnAtm
        component significantly impacts regional ocean mass budgets on
        both spatial and temporal scales, and its importance is
        equivalent to that of barystatic. In regions with pronounced
        seasonal fluctuations (e.g., the Southeast Asian Coast and the
        Red Sea), ocean mass variations are predominantly controlled by
        Nt-OcnAtm. Additionally, the Nt-OcnAtm component is responsible
        for anomalous changes in regional ocean mass, such as the
        significant positive mass anomalies observed in the
        Mediterranean Sea during 2010{\textendash}2011. Furthermore, the
        Nt-OcnAtm component accounts for more than 50\% of the total
        trend budget in five regions. Wind-driven Nt-OcnAtm component is
        also identified as a major source of interannual variability in
        regional ocean mass. These findings underscore the importance of
        the Nt-OcnAtm component in regional ocean mass budgets and
        highlight the necessity of quantifying it separately when
        conducting attribution analyses.}",
