Multimillennial climate-freshwater legacy beneath a large-river delta-front estuary
O collectively confirm its fossil nature rather than slowly circulating modern groundwater. Numerical modeling further constrains the timescale of natural degradation, underscoring the system's resilience. These findings establish ORFG as not only as a long-lived archive of paleohydrological cycles but also as a potential strategic freshwater reserve, with substantial implications for coastal water security in a changing climate.
