Abstract Submarine groundwater discharge (SGD) has been recognized as an important pathway for nutrients into estuaries, coasts, and the adjacent seas. In this study, 222 Rn was used to estimate SGD‐associated nutrient fluxes aquaculture area in a typical tropical bay (Maowei Sea, China). The SGD Maowei Sea during June 2016 estimated be 0.36 ± 0.33 m d −1 associated with SGD‐derived dissolved inorganic nitrogen (DIN), phosphorus (DIP), silicon (DSi) (mol ) of (4.5 5.5) × 10 6 , (5.3 9.1) 4...
Abstract. 7Be and 210Pb air concentration depositional flux data provide key information on the origins movements of masses, as well atmospheric deposition processes residence time aerosols. After their onto Earth's surface, they are utilized for tracing soil redistribution land, particle dynamics in aquatic systems, mixing open ocean. Here we present a global dataset measurements made by large number research communities. Data were collected from published papers between 1955 early 2020. It...
Abstract “Mobile mud” (MM), which has fine grain size distribution (>90% clay + silt, and <5% sand) high porosity (≥0.50), plays an important role in the biogeochemical cycles estuarine areas inshore shelf. A suite of MM samples from coastal area East China Sea (ECS) was collected spring summer 2011 to observe their spatial temporal distribution, size, radionuclides concentrations. The thickness ranged 0.5 11 cm (average: 2.2 (May) 3.9 (August)). thick mud layer is mainly distributed...
This study investigated the distribution features of uranium-238 (238U), radium-226 (226Ra), thorium-232 (232Th), and potassium-40 (40K) evaluated associated environmental radiological hazards topsoil river sediments in Jinding lead-zinc (Pb-Zn) mine catchment from Southwest China. The activity concentrations 238U, 226Ra, 232Th, 40K ranged 24.0 ± 2.29–60.3 5.26 Bq.kg-1, 32.5 3.95–69.8 3.39 15.3 2.24–58.3 4.92 203 10.2–1140 27.4 respectively. highest for all these radionuclides were primarily...
The accumulation rate of recent deposits in a delta environment is critical to the study dynamics and their sustainable management. most commonly used dating approach for (<100 years) based on radionuclide analyses (e.g. 210 Pb, 137 Cs 239 + 240 Pu), while alternative techniques, such as microplastics dating, are emerging. In this study, 180-cm sediment core from Yangtze River (Changjiang) subaqueous was dated using multiple including Cs, Pu geochronology, content, optically stimulated...
Abstract Both magnetic properties and radionuclides are widely used to trace sediment transport in aquatic environments; however, these methods have not been combination. In this study, the East China Sea (ECS), a typical river‐dominated margin, was chosen demonstrate advantages of combining two track movements on seasonal annual timescale. The ratios between saturation isothermal remnant magnetization anhysteretic (χ ARM /SIRM) 7 Be/ 210 Pb ex activity as well mass balance Be provide...
The behavior and source of 90Sr in the coastal ocean remain uncertain. Here, we investigated distributions fresh groundwater, river water, pore seawater three bays along southeastern coast China between 2019 2021 evaluated potential submarine groundwater discharge (SGD) as a 90Sr. activity was higher than that water seawater, while comparable to adjacent seawater. In addition, nonconservative mixing salinity gradient observed. These observations indicated SGD may serve an additional...
