Development of Arsenopyrite Reference Materials (Sacra and Niko) for In situ Multiple Sulfur Isotope Measurement

Geostandards and Geoanalytical Research, EarlyView.
Key Points New arsenopyrite reference materials (Niko and Sacra) for in situ multiple sulfur isotope measurement. Niko and Sacra are homogenous, near‐stoichiometric arsenopyrite. Niko serves as a primary matrix‐matched reference material, with lower measurement repeatability; Sacra is recommended as a secondary reference and quality control material ...

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

Groundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

Toward the astronomical calibration of the Cretaceous : the Maastricthian (Late Cretaceous) and Cretaceous-Paleogene boundary

, 2010
L'approche cyclostratigraphique, qui repose sur l'analyse des cyclicités sédimentaires et l'étude de leurs relations avec les évolutions des paramètres orbitaux de la Terre, a été employée ici dans le but de construire une échelle de temps astronomique pour le Maastrichtien.

Managed Aquifer Recharge Operations and Design under Hydrologic Uncertainty

Groundwater, EarlyView.
Integrated hydrologic modeling uses dual ensembles of MAR operations and IES‐derived parameters to evaluate mounding, inundation, and transport risks under climate extremes. Exceedance‐probability metrics quantify environmental risks across the MAR impact zone, showing drain‐controlled mound limits, recovery effects, and pathways to interdunal and ...
