A harmonized river-ocean coupled database for the northern Gulf of Mexico by Bailey Armos, Shuang Zhang, Tao Wen, Ellie Walker, Prabir Daripa

“…To support large-scale data-driven research centered on the dynamic river-ocean system in the region, this study consolidated hydrogeochemical river and ocean data from across the nGoM. In particular, we harmonized 35 chemical solute parameters from 54 rivers and incorporated river discharge data to derive daily solute concentration and flux estimates throughout the nGoM. …”
