Nutrients from the seabirds’ guano fuels the growth of carbon-storing phytoplankton, but penguin populations have plunged in the past 4 decades.
High-pressure reactions of hydrogen and iron could explain gaps in the distribution of exoplanets.
Un nuevo estudio investiga el estado del hierro en el interior del planeta. Los hallazgos tienen repercusiones para comprender la estructura del núcleo interno.
A new study investigates iron’s form at the planet’s interior. The findings have repercussions for understanding the inner core’s structure.
Understanding greigite formation pathways in sediments is a prerequisite for assessing the marine iron-sulfur-carbon cycle and yield reliable near-syn-sedimentary paleomagnetic records.
The discovery of tiny crystals of the iron-rich hydroxychloride kuliginite in New Caledonia provides new insights into the hydrogen production from mantle rocks and saline water.
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.
The magnetic and color properties of the mineral hematite give clues to past environmental conditions and is being used for paleoclimatic reconstruction.
A comparative study of urban, semi-urban, and rural sites reveals that the species of atmospheric iron varies depending on location.
Researchers validated some steps in the standard sequential chemical technique used to extract different forms of iron from rock samples but found inconsistencies in other steps.
