The paleohydrological evolution of Lago Chungará Andean Altiplano, northern Chile) during the Lateglacial and early Holocene using oxigen isotopes in diatom silica
Oxygen isotopes of diatom silica and petrographical characterisation of diatomaceous laminated sediments of Lago Chungara´ (northern Chilean Altiplano) have allowed us to establish its palaeohydrological evolution during ...
Global CO2 fertilization of Sphagnum peat mosses via suppression of photorespiration during the twentieth century
Natural peatlands contribute signifcantly to global carbon sequestration and storage of biomass, most of which derives from Sphagnum peat mosses. Atmospheric CO2 levels have increased dramatically during the twentieth ...

Data-driven transfer functions from differential magnetometer measurements to enhance GIC model validation capability: A case study in the Spanish power grid
Geomagnetically induced currents (GICs) are unwanted currents flowing in long grounded conductors because of space weather phenomena. Example GICs are those flowing in power transmission lines via grounded transformer ...
Exploring the Connection of XVI-Century Major HistoricalEarthquakes in the Eastern Betic Cordillera, Spain: InsightsFrom Viscoelastic Relaxation of the Lithosphere
Understanding the crustal fault interaction and connection between earthquakes in areas with slow tectonic deformation, such as Betic Cordillera (South Spain), is challenging. When seismic rates are low and large destructive ...
Palaeogene Charophytes of the Balearic Islands (Spain)
Fossil charophytes were recorded in two different stratigraphic units from the non-marine Palaeogene of the Balearic Islands. In the Peguera Limestone Fm. of Mallorca the charophyte flora is characterised by two assemblages. ...
