Elementary, My Dear: Al & Be Give Evidence of Past Climate Change
10Be and 26Al concentrations in river sand reveal an increase in erosion rate in the Brazilian Highlands consistent with the Mid-Pleistocene Transition, a major climatic shift that occurred about 1 million years ago.
Sedimentos radiactivos podrían haber construido los cratones de la Tierra
La meteorización de los primeros continentes podría haber puesto en marcha la formación de cratones, las raíces inmutables de los continentes.
Radioactive Isotopes Trace Hidden Arctic Currents
Tracing anthropogenic radionuclides shows researchers how water from the Atlantic flows into and mingles with Arctic currents.
Radioactive Sediments May Have Built Earth’s Cratons
Weathering of the earliest continents could have set in motion the formation of cratons, the immutable roots of continents.
Digging Deep into Interactions Between the Core and Mantle
A new book presents major advances in our understanding of core-mantle interaction and co-evolution, and showcases technological developments improving our insights into deep Earth processes.
Rare and Revealing: Radiocarbon in Service of Paleoceanography
While radiocarbon is best known as a dating tool, this rare isotope can also provide unique and wide-ranging insights into the cycling of carbon in the Earth system.
Una explosión de radiocarbono del pasado
El fechamiento por radiocarbono es un pilar de la climatología y la arqueología. Sin embargo, esta metodología se encuentra amenazada por las emisiones de combustibles fósiles, que invalidan una señal útil proveniente de pruebas nucleares.
Radiocarbon’s Blast from the Past
Radiocarbon dating is a cornerstone of climate and archaeological sciences. But the method is under threat as fossil fuel emissions negate a useful signal from atomic tests.
Estimating Uranium and Thorium Abundance with Geoneutrinos
Terrestrial electron antineutrino observations provide new constraints on the contributions of radiogenic heat in the mantle.
