The eastern North American population of monarch butterflies are famous for their annual, multi-generational, round-trip migration from the oyamel fir forests of Central Mexico through the United ...

Scientists from Northwestern have published new findings on the factors that triggered the oceanic anoxic event (OAE) 1a in the Early Cretaceous Period about120 million years ago. The unprecedented ...

Strontium isotope geochemistry plays a pivotal role in elucidating Earth’s dynamic processes. By utilising both stable (δ88/86Sr) and radiogenic (87Sr/86Sr) isotopic systems, researchers are able to ...

A team of researchers led by UC Santa Cruz recently released a sophisticated new map that reveals, for the first time, the unique “geologic fingerprints” for most of the African continent. The map ...

Pre-COVID-19 pandemic, University of Ottawa biology student Megan Reich enjoyed the road trip of a lifetime, crisscrossing the east coast of the United States in search of a specific thrill: Milkweed.

The ratios of strontium isotopes in fossil shark teeth can be used to better understand how coastal environments evolved in ancient times, according to our newly published work. Our study was one of ...

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years.

Your teeth contain traces of strontium isotopes that can reveal where you lived while they were forming. Hosted by: Michael Aranda ---------- Dooblydoo thanks go to the following Patreon supporters -- ...

A drama has been unfolding in the corridor outside Matthew Wooller’s lab at the University of Alaska. That’s where he and his colleagues tape up large sheets of paper mapping levels of strontium, ...

Marine barite extracted from deep-sea sediment cores, seen here in a scanning electron microscope image, provides a record of variations in ocean chemistry over geologic time. (Image by Adina Paytan) ...
