Forty years after the explosive eruption of Mount St. Helens, scientists, communities, and civic officials are evaluating plans to best protect public health before, during, and after an eruption.Read More »Geochemistry, Mineralogy, Volcanology
Using beryllium isotopes to track in situ formation of clays in the ocean, known as reverse weathering, will improve global models of atmospheric carbon dioxide and ocean alkalinity.Read More »Geochemistry, Mineralogy, Volcanology
Volcanoes can warm as much as they cool. Prior simulations have neglected the important warming effects of sulfur dioxide emissions, making some results colder than they should be.Read More »Planetary Sciences
New analyses of oxygen isotopes reveal terrestrial and lunar rocks aren’t as similar as previously thought, potentially changing the way we think the Moon formed.Read More »
Last year’s rumblings beneath New Zealand’s Taupō supervolcano, the site of Earth’s most recent supereruption, lend new urgency to research and outreach efforts in the region.Read More »Biogeosciences
An innovative collaboration is investigating how geobiological processes alter fluxes of carbon and other materials between the deep Earth and the surface.Read More »Geochemistry, Mineralogy, Volcanology
Living in Geologic Time: Every one of the Pacific Northwest’s volatile volcanoes is likely to erupt again before the range goes extinct.Read More »Climate Change
Oxygen isotope ratios in cave deposits reflect past climates, but interpreting these data is not straightforward. A new study explores what these ratios really tell us.Read More »
Tree rings reveal how severe cold and political isolation brought disaster to Scotland, inspired a colonization effort in Panama, and helped drive union with England.Read More »
The newly named period in the Pleistocene identifies a key moment in geological history: the last time Earth’s magnetic poles switched places.Read More »
