Soil moisture estimates, inferred from thousands of tree rings spanning the past 12 centuries, highlight the severity of the recent record-breaking drought.
A new model makes a direct estimate of contaminants in submarine groundwater discharge.
NASA's MESSENGER spacecraft discovered electric currents in Mercury's magnetosphere directed toward and away from the planet. Do the currents reach the planet? If so, where do they go?
Metallic plasma layers in Earth's ionosphere interfere with radio communications and produce odd echo behavior at specific frequencies.
Twenty years of ground motion observations show that seismic strain is accumulating south of Istanbul.
Researchers use computer simulations to find the date and earthquake source of an ancient tsunami that deposited sediment in a Hawaii sinkhole.
Researchers investigate how microbes respire in dry conditions.
A study of water temperature in nearshore environments shows that wave energy was the second-largest driver of temperature changes in the surf zone.
A new technique brings accurate models of traveling seismic waves to a regional scale.
An idealized climate model suggests polar warming stabilizes the jet stream and reduces atmospheric blocking at midlatitudes.
