The earliest instrumental records of Earth’s climate, as measured by thermometers and other tools, start in the 1850s. To look further back in time, scientists investigate air bubbles trapped in ice cores, which expands the window to less than a million years. But to study Earth’s history over tens to hundreds of millions of years, researchers examine the chemical and biological signatures of deep sea sediment archives.

New light has been shed on the processes by which ocean water enters the solid Earth during continental breakup. Research led by geoscientists at the University of Southampton, and published in Nature Geoscience this week, is the first to show a direct link on geological timescales between fault activity and the amount of water entering the Earth’s mantle along faults.
New research in Nature Communications sheds light on what happens when a supervolcano erupts. The study combines recent lab tests with vintage field data — some of it captured in colorful Kodachrome slides — to provide insight on how rivers of hot ash and gas travel huge distances in supereruptions.
University of Chicago scientists have discovered evidence in a meteorite that a rare element, curium, was present during the formation of the solar system. This finding ends a 35-year-old debate on the possible presence of curium in the early solar system.
When UO historian Mark Carey hired Jaclyn Rushing, an undergraduate student in the Robert D. Clark Honors College, to explore how nongovernmental organizations were addressing melting Himalayan glaciers, he got an unexpected return.
A Florida State University student has cracked the code to reveal the deep and interesting history of an ancient meteorite that likely formed at the time our planets were just developing.

In their article for Geosphere, R. Craig Kochel and colleagues discuss the geomorphic impact of the flooding caused Tropical Storm Lee in September 2011 on several large watersheds of the Susquehanna River in the Appalachian Plateau region of north-central Pennsylvania. Unlike many Appalachian floods, the physical impacts to channels and floodplains were extensive.
Reconstructing the magnitude of past volcanic eruptions is important in informing predictions about future eruptions and hazards. This is difficult to accomplish from records on land -- old eruptions are often eroded away, buried beneath later eruptions, or obscured by vegetation and soil. Most volcanoes are close to the oceans, so much of the erupted material falls into seawater and accumulates on the seafloor.
Geologists investigating an unusual landform in the Wabash River Valley in southern Illinois expected to find seismic origins, but instead found the aftermath of rushing floodwaters from melting Midwestern glaciers after the last ice age. The finding could give clues to how floodwaters may behave as glacier melt increases today in places like Greenland and Iceland.
