Arctic coring expedition continues to yield new clues

For the second time in as many months, the IODP Arctic Coring Expedition (ACEX) is making news with new analysis of ocean-floor sediments. In the Aug. 10 issue of Nature, an article by several of the expedition scientists summarizes their findings: more evidence that the Arctic was extremely warm, ...

Scripps studies offer new picture of Lake Tahoe's earthquake potential

...SA), Scripps graduate student Danny Brothers investigated the rupture history of the West Tahoe Fault in greater detail. Using comprehensive CHIRP and coring surveys of Fallen Leaf Lake, where the West Tahoe Fault crosses the southern end of the lake, the study confirmed the suspected fault length of over 5...

CO2 drop and global cooling caused Antarctic glacier to form

...olecules were assayed in ocean cores collected by the Integrated Ocean Drilling Program (IODP) and earlier marine programs that study Earth history by coring deep-ocean sediments and crust around the world. "Temperatures in some regions, just before the Antarctic glaciers formed, were surprisingly highe...

Newfound ancient African megadroughts may have driven the evolution of humans and fishes

... Institution funded the research. Cohen and his colleagues have been working for years to learn more about ancient Africa's climate and ecology by coring Africa's deepest lakes. The scientists discovered the ancient megadroughts by studying sediments cored from the bottom of Lake Malawi, an African r...

Scientists launch deep-sea scientific drilling program to study volatile earthquake zone

...eginning of a new tomorrow, where the Chikyu enables us to explore the origins of devastating earthquakes at their source, study Earth history through coring of unstable, thick sediment sections, and investigate the fundamentals of ocean crust formation. These new capabilities," Allan notes, "complement tho...
