Paleosuelos de sepiolita en el neógeno de la cuenca de Madrid
Estudios Geologicos, 1989 El análisis de la composición mineral de materiales arcillosos con sepiolita, pone de manifiesto variaciones significativas en el contenido de este mineral, con respecto a esmectitas e illitas, minerales terrígenos (cuarzo y feldespato) y carbonatos ...

Probiotics mitigate thermal stress- and pathogen-driven impacts on coral skeleton
Frontiers in Marine Science, 2023 Threats leading to a reduction in coral populations are apparent worldwide. Several different approaches have been tested to accelerate the adaptation of corals to a changing climate. Here, we evaluated the skeleton structure, crystal habit, and chemical

Multi‐Element Soil‐Geochemistry Dataset, La Negra Formation, Chile
Geoscience Data Journal, Volume 13, Issue 3, July 2026.We release a single‐protocol, fine‐earth (< 2 mm) soil‐geochemistry dataset of 101 soils, 15 field duplicates and 7 outcrop rock pulps, collected on two parallel north–south transects spanning six sectors of the La Negra Formation (Atacama Desert, Chile); 62 aqua‐regia‐extractable analytes by ICP‐MS, with six trace metals cross‐checked by AAS ...

Methane and Nitrous Oxide Reshape the Air‐Water Greenhouse Gas Budget of a Tropical Estuarine Delta
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.Abstract Estuaries are important sources and sinks of greenhouse gases (GHGs), yet assessments of their radiative balance often focus primarily on carbon dioxide (CO2), with less attention given to methane (CH4) and nitrous oxide (N2O). We combine measurements of CH4 and N2O air‐water fluxes with concurrent CO2 data in a tropical estuarine delta ...

Hydrological Processes, Volume 40, Issue 5, May 2026.Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...
