Electrons energized and trapped at Mars were thought to lose energy inside the planet’s magnetosheath, but new research suggests a different explanation of spacecraft data.Read More »Biogeosciences
Arctic coastlines have not been considered carefully in carbon cycles for long, but new research suggests that eroding permafrost may emit more greenhouse gases than previously thought.Read More »Biogeosciences
A new boron isotope record from South Pacific marine sediments offers a more complete picture of ocean-atmosphere carbon dioxide exchange during the late Pleistocene.Read More »
A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.Read More »Biogeosciences
New research looks at how changes in the arrangement of trees and canopy thickness influence the transport of water from the land surface to the atmosphere.Read More »Biogeosciences
New modeling indicates that global subsurface ocean currents distribute submerged microplastics along very different routes than those traveled by floating plastic debris.Read More »Climate Change
Past ocean surface conditions suggest that over the past 800,000 years, atmospheric carbon dioxide levels typically rose on millennial timescales when Atlantic overturning was weaker and vice versa.Read More »
A high-resolution map of surface displacements indicates that the 2017 Chiapas earthquake caused substantial creep along a segment of the San Andreas Fault, located 3,000 kilometers away.Read More »Hydrology, Cryosphere & Earth Surface
The northern Bering Sea is experiencing record-setting low winter sea ice levels, which are impacting plankton, fish, and other animals in the region.Read More »
