摘      要：Submarine groundwater discharge(SGD)has received increasing attention by studies on coastal areas;however,its effects on biogeochemical zonation have not been investigated to *** Huanghe River Estuary(HRE)is a world class river estuary with high turbidity,and heavy human *** study investigated how SGD is related to the benthic biogeochemistry of the *** on the distribution of several parameters(e.g.,salinity,temperature,dissolved oxygen(DO)levels,p H,radium isotopes,and nutrients),the HRE was subdivided into six different zones,and the SGD fluxes within each zone were quantified and *** highest SGD flux was found in the northwest nearshore zone,where it was more than one order of magnitude higher than in the offshore *** SGD resulted in low DO and p H,but high nutrient levels in the benthic boundary *** southeast nearshore zone was also characterized by high SGD flux,but benthic waters were more oxic because of the dominating inputs by the Huanghe *** data suggest that such a zonation would help to understand benthic biogeochemical *** SGD may not only contribute to the estuarine nutrient budget,but may also contribute to the formation of hypoxia and acidification.
