Göttingen University researchers analysed oxygen isotopes from corals, like this Acropora coral, to expand the uses of the “triple oxygen isotope” method and help measure temperatures from the past ...

A new analysis of chemical signatures measured by NASA's Curiosity Rover gives a peek at Mars's past to a time some 3.7 billion years ago, when it was warmer and wetter. Through measurements of ...

Triple oxygen isotope research has emerged as a powerful tool to enhance our understanding of hydrological processes and past climate variability. By simultaneously analysing δ18O, δ17O, and the ...

An international team, led by Professor Chenxi Xu from the Institute of Geology and Geophysics, Chinese Academy of Sciences, has generated the first continental-scale isoscapes of δ¹⁸O TR across Asia ...

AMES, Iowa – Alan Wanamaker, working as a postdoctoral researcher from 2007 to 2009, was charged with beginning to compile a 1,000-year record of the marine climate for a spot in the North Atlantic ...

Researchers have applied a temperature proxy to exceptionally well-preserved fossil phytoplankton for the first time. The results suggest that conditions in the North Atlantic have been cooler than ...

A new study reveals that the aerobic nitrogen cycle in the ocean may have occurred about 100 million years before oxygen began to significantly accumulate in the atmosphere, based on nitrogen isotope ...

Today’s climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. By analyzing clues contained in rocks, scientists at the ...

Early warning of climate risk is the gold standard that scientists, managers and governments are working towards. Doing this requires a detailed understanding of not just the amount of precipitation ...

On Thursday, Apr. 2, paleoclimatologist and professor Jessica Conroy, Ph.D., delivered Geneseo’s 22nd Annual American Rock ...
