Resumo O transporte médio anual de sedimentos em suspensão no rio Amazonas, em Óbidos, Brasil, foi estimado, a partir de novas medições, em 0,8 a 0,9 x109 ton. ano. A maior parte destes sedimentos é lançada na pla...

The lowermost part of the Agua de la Mula Member (upper Hauterivian), Agrio Formation, was studied in distal depositional settings at four locations in the central Neuquén Basin. Detailed sedimentological and ichnologic...

Sediment deposits formed mainly under the influence of bottom currents (contourites) are widely used as high-resolution archives for reconstructing past ocean conditions. However, the driving processes of Contourite Depo...

Abstract Microplastic pollution in freshwater is a global concern, yet field monitoring often lacks standardization, hindering data comparability and analysis. This systematic review bridges the gap between lab findings ...

River confluences are notable features in the drainage system with complex hydrodynamics, bed morphology, sediment transport, and mixing processes. Junction planform plays a pivotal role in the confluence hydrodynamics. ...

Submarine landslides can generate complicated patterns of seafloor relief that influence subsequent flow behaviour and sediment dispersal patterns. In subsurface studies, the term mass transport deposits (MTDs) is common...

Different morphotypes of vertically embedded ammonoid shells are abundant in the 1-km-thick deposits of the Santa Marta Formation, Antarctica, that record the evolution of a deep-water delta system. Vertical shells depos...

Abstract A local tropical cyclone (TC) in South China Sea was observed making its first complete landfall on an island. Following the arrival of the TC eye, PM2.5 concentration rose from 4 µg/m³ to 44 µg/m³. Mass r...

The aim of this work is to assess the risk of groundwater contamination associated with BTEX dissolution from fuels as a residual phase. Numerical simulations of sixty scenarios were carried out with the software HYDRUS ...

Abstract Quantifying luminescence signal resetting of sand grains in turbid waters is essential for both sediment dating and tracing, yet direct measurement under natural subaqueous conditions remain scarce. Here, we pre...

Abstract Submarine fan deposits are important archives of Earth's history and serve as the record of turbidity current events that transfer large amounts of terrestrial sediment and carbon into the ocean. The geomorpholo...

Abstract Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants of global concern due to their widespread occurrence, environmental persistence, and well-documented adverse effects on human health. In ...

Abstract Lead (Pb) isotopes are powerful tools for tracing dust provenance and reconstructing paleoclimate. However, variations in Pb isotopic compositions among different grain‐size fractions in sediments complicate t...

La Formación Vinchina fue depositada entre los 16 y 8 Ma en una cuenca de antepaís fracturada del noroeste de la Argentina, registrando sedimentación en ambientes continentales, alcanzando un espesor de 6 kilómetros....

Abstract This study examines the geological and climatic factors that influence natural radioactivity levels in drinking water from Dessie and Kombolcha towns in Ethiopia’s northern plateau. The basaltic and sedimentar...

Underwater gas pipelines are vital for energy transportation but are often subjected to harsh environments, and any leakage can have significant environmental consequences. Substantial underestimation of gas plume format...

We investigate the use of Hg as a proxy for volcanism by studying four distal and two proximal sections in relation to the Deccan volcanic center, straddling the Cretaceous-Paleogene (KPg) boundary at (a) Højerup (Denma...

Watershed models are powerful tools for simulating the effect of watershed processes and management on soil and water resources. However, no comprehensive guidance is available to facilitate model evaluation in terms of ...
