Large-river deltaic estuaries and adjacent continental shelves have experienced multiple phases of transgressions regressions to form interlayered aquifer-aquitard systems are expected host vast paleo-terrestrial groundwater hundreds kilometres offshore. Here, we used offshore hydrogeology, marine geophysical reflections, porewater geochemistry, paleo-hydrogeological models, identified a previously unknown freshened body with static volume up 575.6 ± 44.9 km3 in the Pearl River Estuary...
The existence of offshore freshened groundwater (OFG) has been well recognised over the globe but studies on chemistry OFG are extremely limited due to scarcity dedicated drilling investigations. In this study, we integrate hydrogeology, geochemical and isotopic tracers, transport modelling quantitatively evaluate hydrochemical characteristics persistence an system in Pearl River Estuary its adjacent shelf. Offshore suggests comprises a vast low-salinity body extending up 180 km offshore,...
Eutrophic shallow lakes are hotspots of carbon (C) and nitrogen (N) accumulation transformation, increasingly recognized as important sources greenhouse gases (GHGs: CO2, CH4 N2O). Lacustrine groundwater discharge (LGD) is a crucial component the water budget terrestrial material delivery for lakes, but its interplays with intrinsic C-N biogeochemical processes remain less tackled. In this study, C N ingredients multiple stable isotopes (δ2H, δ18O, δ13C,...
This review is motivated by deep concern over the current, relatively fragmented state of lake and groundwater research. For example, Chinese mega basins such as Lake Taihu, Dongting, Poyang, Hongze, Chaohu are not only major cropland areas but also habitats for 120 million residents. These lakes have faced serious issues decades, rapid shrinking water volume in severe eutrophication algal blooms Taihu Chaohu. Despite significant efforts environmental limnology scientists to prevent these...
Abstract Coastal groundwater reservoirs are sensitive to the complicated evolution of marine transgressions and regressions in river delta regions. We integrated hydrogeological investigation hydrogeochemical data with numerical modeling assess system Pearl River Delta’s aquifer (in southeastern China). studied effects flow dynamics redox conditions on biogeochemical processes nutrients regional systems response transient states related variable paleoprecipitation seawater salinity decline...
The ~100 ka Milankovitch cycles during the Quaternary generated a significant sea level fluctuation with lowest of 120 m below present at Last Glacial Maximum in coastal areas. large-river deltaic estuaries (LDEs), due to proximity environments, therefore, may archive periodical transgression and regression information. During delta-front progradation, sedimentation process is usually dominated by coarse-grained fluvial deposits, river networks extend further sea, whereas marine...
Inland lakes are hotspots for global carbon (C) emission, and C pathways in these may change along with the eutrophic states. Lacustrine groundwater discharge (LGD) is recognized as one of significant nutrient sources to induce eutrophication, also a crucial conduit CH4 CO2 lakes, but its regulation on behaviors remains unclear. Here we conducted continuous monitoring 222Rn, CO2, δ13C at two sites distinctive algal density large lake (Lake Taihu) China, delineated synergy LGD biomass...
