Una técnica que mide la relación entre el dióxido de carbono producido y el oxígeno consumido podría mejorar las predicciones de la respuesta del suelo al cambio climático.
Mantle rocks in Papua New Guinea contain curious geochemical signatures that scientists have traditionally interpreted as evidence of billions-year-old melting. New evidence suggests otherwise.
New climate records from a peat bog show how two neighboring cultures responded differently to shifts in climate and ocean currents.
New instrumentation and growing modeling needs in the Earth sciences are driving a renewed effort to compile and curate seawater oxygen isotope data in a centralized, accessible database.
To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
If subduction carries hydrous minerals deep into Earth’s mantle, they may “rust” the iron outer core, forming vast sinks of oxygen that can later be returned to the atmosphere.
A technique that measures the ratio of carbon dioxide produced to oxygen consumed could improve predictions of soil’s response to climate change.
Helium isotopes found in water samples provide a snapshot of what lies beneath the plateau and stimulate debate within the geosciences community.
The discovery, gleaned from observations of volcanoes on four continents, could help constrain models of volcanic eruptions.
A new study has spurred further research into the impacts of soil formation on modern-day problems like heavy metal contamination in agricultural soils.
