Abstract The Taiwan Warm Current (TWC) has an overwhelming influence on the heat, salt, and nutrients balance one of broadest shelf in world, East China Sea shelf. In winter, TWC flows unusual upwind direction reaches Changjiang (Yangtze River) Estuary, but its origin pathway are intensely debated. Here combined evidences from current measurement, hydrographic, stable isotopic data all suggest that wintertime intrusion off Estuary mainly originates Kuroshio subsurface water northeast Taiwan,...

Background Listeriosis, caused by Listeria monocytogenes ( L. ), is a severe infectious disease with high hospitalization and fatality rates. Urgent epidemiological studies on this geographic variability are needed, particularly in developing countries. Methods This study included non-perinatal patients listeriosis from four tertiary centers Shandong, China. Data demographics, clinical characteristics, outcomes were collected retrospectively over 8 years (2015–2022). Results Among 292,254...

Abstract Background Seasonal variations of stable hydrogen and oxygen isotopes in river water can be used to indicate hydrological processes the cycle basin. This study presents a high-resolution time series isotopic record (δ 18 O) lower Changjiang (Yangtze) River mainstream aims investigate regional concerning natural climate changes anthropogenic activities. Results The δ O shows apparent seasonal variations, which is overall higher during dry season flood season. basin-scale variation...

Abstract Chemical composition of river sediments and dissolved load is classically used to infer controls on continental weathering and, therefore, exert an important role the understanding global carbon biogeochemical cycles. To date, most studied basins are strongly impacted by dam constructions; however, effects dams sediment chemical compositions little known. The Three Gorges Dam one largest in world began impounding water 2003 Changjiang basin. In order investigate impact this...

Lithium isotopes in marine authigenic or detrital sedimentary archives have been recently used to trace continental weathering over geologic timescales.However, interpretations are predominantly based on the assumption that riverine Li isotopic signals can be propagated through estuaries without modification.Here, we verify this hypothesis by investigating behaviour of Changjiang (Yangtze) River estuary.We observe a conservative mixing dissolved and its between water seawater.The δ 7 yields...

Abstract Copper-bearing sandstones and shales of Yunnan, China are found in Jurassic Cretaceous red beds the central eastern Yunnan paraplatform western parageosyncline. Several such deposits, which author states some size good quality, have been explored last few years. The copper-bearing sandstone shale deposits range from typical syngenetic to hydrothermal with transitional types. primary formed as precipitation copper minerals shale, sandstone, local conglomerate lacustrine delta facies...

Chemical weathering plays an important role in regulating biogeochemical cycle and global climate.Lithium (Li) isotopes are considered as one of the most powerful tracers silicate weathering, which have been widely investigated by field and/or experimental studies.However, relatively little is known about Li isotopic fractionation during strong processes, restrains our application to trace past weathering.In this study, we analyzed elemental, mineralogical compositions bulk clay-sized...
