Hydrologically sensitive carbonates: Tectonic and groundwater controls on synrift sedimentation in the Late Jurassic–Early Cretaceous of the western Cameros Basin, Northern Spain

The Depositional Record, EarlyView.
Late Jurassic extension, footwall uplift, erosion and karstification of marine Jurassic carbonates in the western Cameros Basin (Spain) resulted in the deposition of ?Upper Kimmeridgian‐Tithonian syntectonic alluvial fan deposits and a series of ?Tithonian to Berriasian distal alluvial marls, palustrine, lacustrine and finally lagoonal carbonates.

Population genomic analysis of the Speckled Dace species complex identifies three distinct lineages in California

Transactions of the American Fisheries Society, Volume 151, Issue 6, Page 695-710, November 2022., 2022
Abstract Objective Speckled Dace Rhinichthys osculus is small cyprinoid fish that is widespread in western North America. In California and elsewhere it is currently treated as a single species with multiple subspecies, many undescribed. However, these subspecies may represent evolutionary lineages that are cryptic species because they cannot be ...

Natural organic matter in sedimentary basins and its relation to arsenic in anoxic ground water: the example of West Bengal and its worldwide implications [PDF]

, 2004
In order to investigate the mechanism of As release to anoxic ground water in alluvial aquifers, the authors sampled ground waters from 3 piezometer nests, 79 shallow (80 m) wells, in an area 750 m by 450 m, just north of Barasat, near Kolkata (Calcutta),

Anatomy of modern sedimentary volcanoes produced by gas‐charged groundwater liquefaction, Lake Powell, Hite, Utah: Implications for the recognition and interpretation of ancient sedimentary volcanoes

The Depositional Record, EarlyView.
Two non‐seismically generated sedimentary volcanoes were excavated on the Colorado River delta in Lake Powell, Utah, USA, in order to characterise the internal structures. Sedimentary volcanoes are commonly employed as tools in palaeoseismic reconstruction, thus it is important to establish criteria to differentiate non‐seismic‐generated sedimentary ...

Colloidal transport of heavy metals in low‐advective‐velocity environmental systems: Reactive transport model on biogeochemical and hydrodynamic impacts

Vadose Zone Journal, Volume 22, Issue 1, January/February 2023., 2023
Abstract In this study, the impact of colloid facilitated transport of heavy metals on the overall biogeochemical processes is demonstrated in example Lake Coeurd'Alene sediments. Release and transport of heavy metals (Pb and Zn) on initially sorbed colloidal Fe (hydr)oxide minerals are compared with immobile surfaces under various advective flow ...

Combining the Morris Method and Multiple Error Metrics to Assess Aquifer Characteristics and Recharge in the Lower Ticino Basin, in Italy [PDF]

arXiv, 2022
Groundwater flow model accuracy is often limited by the uncertainty in model parameters that characterize aquifer properties and aquifer recharge. Aquifer properties such as hydraulic conductivity can have an uncertainty spanning orders of magnitude. Meanwhile, parameters used to configure model boundary conditions can introduce additional uncertainty.

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

The Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Future Changes in Global Runoff and Runoff Coefficient From CMIP6 Multi‐Model Simulation Under SSP1‐2.6 and SSP5‐8.5 Scenarios

Earth's Future, Volume 10, Issue 12, December 2022., 2022
Abstract This paper assesses the performances of runoff (Ro) and runoff coefficient (α, the ratio of runoff to precipitation) simulations from 23 models during the historical period and then projects their future changes under the two emission scenarios (SSP1‐2.6 and SSP5‐8.5) in the Coupled Model Intercomparison Project.
