Modern and ancient tidal sedimentary systems in the era of energy transition: Introduction to the special volume of The Depositional Record

open access: yesThe Depositional Record, EarlyView.
This volume examines tidal sedimentary systems through 11 articles, spanning ancient and modern tidalites, technological advances and implications for human management. Highlighting contributions from Tidalites 2022 and beyond, it underscores tidalites' significance in sedimentology, environmental forecasting and energy transition, reflecting decades ...

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

open access: yesTransactions 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 ...

Seismic response of the geologically complex alluvial valley at the "Europarco Business Park" (Rome - Italy) through instrumental records and numerical modelling [PDF]

open access: yes, 2016
The analysis of the local seismic response in the “Europarco Business Park”, a recently urbanized district of Rome (Italy) developed over the alluvial valley of the “Fosso di Vallerano” stream, is here presented.

Fifty years of research on the Joulters ooid sandbody—Impact on carbonate sedimentology and diagenesis and lessons learned from an invaluable analogue

open access: yesThe Depositional Record, EarlyView.
The Joulters ooid sandbody of northern Great Bahama Bank is a vast expanse of muddy ooid sands partly rimmed by clean ooid sands and formed into a relatively thick layer of significant extent. Knowledge of the development of depositional and diagenetic patterns in the Joulters example has forwarded our general understanding of carbonate sedimentology ...

Molecular insights on the conflicting generic boundaries in the Carduncellus‐Carthamus complex (Compositae)

open access: yesTAXON, Volume 71, Issue 6, Page 1268-1286, December 2022., 2022
Abstract The Carthamus‐Carduncellus complex is formed by approximately 50 taxa that are widely distributed throughout the Mediterranean basin and western Asia. The generic delineation of this complex has always been controversial. Currently, there are three widely diverging taxonomical proposals, suggesting that the complex is formed by (1) a single ...

Landscape response to Pleistocene-Holocene precipitation change in the Western Cordillera, Peru: 10Be concentrations in modern sediments and terrace fills [PDF]

open access: yes, 2013
The landscape response to climate change is frequently investigated with models because natural experiments on geologic timescales are rare. In Quebrada Veladera, in the western Andes Mountains, the formation of alluvial terraces during periods of high ...

One million year old groundwater in the Sahara revealed by krypton-81 and chlorine-36 [PDF]

open access: yes, 2004
Measurements of 81Kr/Kr in deep groundwater from the Nubian Aquifer (Egypt) were performed by a new laser-based atom-counting method. 81Kr ages range from \~2x10^5 to ~1x10^6 yr, correlate with 36Cl/Cl ratios, and are consistent with lateral flow of groundwater from a recharge area near the Uweinat Uplift in SW Egypt.

Two types of modern sediment dispersal systems in the western Taiwan foreland basin: Sediment transfer from basin to basin

open access: yesThe Depositional Record, EarlyView.
A classical peripheral foreland basin is bounded longitudinally by a pair of marginal ocean basins (DeCelles & Giles, 1996). The WTFB sediments transfer to adjacent marginal ocean basins. The western Taiwan foreland basin (WTFB) is regarded as a classical peripheral foreland basin, longitudinally bounded by the southern Okinawa Trough (SOT) to the ...

Estimation of groundwater recharge using the cumulative rainfall departure method for Bac Lieu province, Mekong Delta, Vietnam [PDF]

open access: yesГеосистемы переходных зон
Estimation of the groundwater (GW) recharge from rainfall is important for determining GW resources in water resources development and management. GW is currently extensively exploited and is an important source of freshwater for people in the Mekong ...

The bifurcation structure and noise induced transitions in the Pleistocene glacial cycles [PDF]

open access: yesarXiv, 2009
The glacial cycles are attributed to the climatic response of the orbital changes in the irradiance to the Earth. These changes in the forcing are to small to explain the observed climate variations as simple linear responses. Non-linear amplifications are necessary to account for the glacial cycles.
