paleoclimatology & paleoceanography
Tiny Marine Shells Reveal Past Patterns in Ocean Dynamics
A 400,000-year calcium carbonate record from the ocean floor sheds light on deep-ocean circulation and on mechanisms driving climate patterns and atmospheric carbon dioxide concentrations.
How Did Life Recover After Earth’s Worst-Ever Mass Extinction?
Ocean animals at the top of the food chain recovered first after a cataclysm at the end of the Permian period. The extinction was triggered by events resembling the changes brewing in today’s oceans.
How Old Is the Mekong River Valley?
Granite samples collected from the Mekong River Valley reveal that the river’s path was incised roughly 17 million years ago, most likely by increased erosion from monsoon precipitation.
Severe Drought May Have Helped Hasten Ancient Maya’s Collapse
Chemical signatures from sediments in lake cores reveal that the centuries-long drought during the fall of Classic Maya civilization was worse than researchers had imagined.
Scraping Bottom: Iceberg Scours Reveal North Atlantic Currents
A 3-D seismic analysis of Pleistocene iceberg gouges indicates that surface currents in the Norwegian Sea flowed northward and remained consistent during numerous glacial cycles.

Radiocarbon in the Oceans
Offsets in radiocarbon concentration within the ocean or between the ocean and the atmosphere are particularly useful proxies for a variety of studies.
