In Japan’s submarine Nankai Trough, rock permeability is much higher when measured at larger scales, likely because of big fractures and faults that are not captured at small scales.Read More »
Upwelling hinders an efficient method to estimate a key measure of biological productivity in coastal waters, but accounting for surface temperatures could boost accuracy.Read More »Atmospheric Sciences
Since the 1970s, the stratosphere has cooled as ozone levels dropped and carbon dioxide levels increased. Chemical models of the temperature decline conflicted with satellite observations—until now.Read More »Climate Change
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.Read More »Atmospheric Sciences
A new study in the Baltimore-Washington metropolitan area reveals prior estimates may significantly underrepresent methane emissions, particularly from landfills and natural gas systems.Read More »Geochemistry, Mineralogy, Volcanology
High-precision airborne measurements, in combination with atmospheric modeling, suggest that the Katla subglacial caldera may be one of the planet’s biggest sources of volcanic carbon dioxide.Read More »
New data synthesis suggests that varying rates of trench retreat along the margin of the Gondwana supercontinent were responsible for the curvature of the Tasmanide mountain chains.Read More »Geohealth
Nitrogen released into the soil from thawing permafrost in the Arctic could accelerate soil carbon decomposition and alter carbon dynamics, with global implications.Read More »Geology & Geophysics
The second-generation Antarctic Digital Magnetic Anomaly Project offers a powerful new tool for probing the structure and evolution of the southernmost continent’s lithosphere.Read More »
