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.
We know there were animals during Earth’s chilliest era. The question is, What did they look like?
The reconstructed loss of molybdenum during the Toarcian ocean anoxic event suggests deeply anoxic conditions during this time period allowing massive amounts of organic carbon being buried.
Bhattacharya et al. present evidence that expansion of the North American Monsoon explains a wetter southwest in the mid-Pliocene and suggest this mechanism can explain current monsoon variations.
Researchers found evidence for a strengthening El Niño in living and fossilized Galápagos corals.
Reactive gases like ozone are hard to preserve, but clumped isotopes and models provide clues to past ozone and suggest a global increase in wildfire at megafaunal extinction.
High-resolution imagery of newly discovered paleolakes shows a period of consistent liquid water flow.
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.
A new 620,000-year climate record from East Africa reveals dramatic swings between wet and dry conditions that may have influenced human evolution.
The Nullarbor Plain has been relatively untouched by geological forces, leaving traces of the continent’s deep past.
