This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by need for stronger harmonisation research efforts. The procedure involved public consultation through online media, followed two workshops which large number potential science questions were collated, prioritised, and synthesised. In spite diversity participants (230 scientists total), process revealed much about priorities state our science: preference continuity...
Carbon and sulfur isotopic data, together with biomarker iron speciation analyses of the Hovea-3 core that was drilled in Perth Basin, Western Australia, indicate euxinic conditions prevailed paleowater column during Permian-Triassic superanoxic event. Biomarkers diagnostic for anoxygenic photosynthesis by Chlorobiaceae are particularly abundant at boundary into Early Triassic. Similar contemporaneous seas off South China. Our evidence widespread photiczone suggests sulfide toxicity a driver...

Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are conjugated ethanol metabolites formed in low amounts after alcohol consumption. Compared with ethanol, EtG EtS excreted urine for a prolonged time, making them useful as sensitive biomarkers. This study determined the detection times alcoholic patients undergoing detoxification.Alcohol-dependent (n = 32) an initial concentration >or=1 g/L based on breath testing were followed during detoxification. Urine samples determination of EtG, EtS,...
We investigated the rates of main microbiological processes (primary production, aerobic and anaerobic carbon degradation) transport phenomena in an intertidal sand plate with a combination situ microsensor measurements incubations. The was coarse, organically poor (0.6–1 mg total organic per gram dry weight sediment), highly permeable to water flow (k = 1.5–7 x 10−11 m2). Aerobic respiration ranged from 105 175 mmol m2 d−1, sulfate reduction 0.08 13.7 net primary production ≪35 d−1. In...
Abstract Single-cell transcriptomic profiling is a powerful tool to explore cellular heterogeneity. However, most of these methods focus on the 3′-end polyadenylated transcripts and provide only partial view transcriptome. We introduce C1 CAGE, method for detection transcript 5′-ends with an original sample multiplexing strategy in TM microfluidic system. first quantifiy performance CAGE find it as accurate sensitive other then use profile promoter enhancer activities response TGF-β lung...
Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil (SOC) stocks provide an important resource for researchers, natural managers, and policy-makers working towards the protection, restoration, valuation these ecosystems. We collated a global dataset tidal marsh (MarSOC) from 99 studies that includes location, depth, site name, dry bulk density, SOC, and/or matter (SOM). The MarSOC 17,454 points 2,329 unique locations, 29 countries. generated...
Abstract Terrestrial groundwater travels through subterranean estuaries before reaching the sea. Groundwater‐derived nutrients drive coastal water quality, primary production, and eutrophication. We determined how dissolved inorganic nitrogen (DIN), phosphorus (DIP), organic (DON) are transformed within estimated submarine discharge (SGD) nutrient loads compiling > 10,000 samples from 216 sites worldwide. Nutrients exhibited complex, nonconservative behavior in estuaries. Fresh DIN DIP...
The Chicxulub asteroid impact event at the Cretaceous-Paleogene (K-Pg) boundary ~66 Myr ago is widely considered responsible for mass extinction leading to demise of non-avian dinosaurs. Short-term cooling due massive release climate-active agents hypothesized have been crucial, with S-bearing gases originating from target rock vaporization an important driving force. Yet, magnitude S remains poorly constrained. Here we empirically estimate amount impact-released relying on concentration and...
