From sediment cores to speleothems, environmental archives are helping us to understand the history of wildfires.
Quantifying the Potential of Forestation for Carbon Storage
Forestation projects in southern China over the past few decades have sequestered large amounts of carbon in tree biomass, but the region is approaching saturation of forest carbon storage capacity.
Titanic Caves and Where to Find Them
More than 21,000 pits, depressions, and closed valleys on Titan may provide access to underground voids or caves.
Groundwater May Fix as Much Carbon as Some Ocean Surface Waters
Microbes from wells as deep as 90 meters created organic carbon at a rate that overlaps with some nutrient-poor spots in the ocean.
Dyes and Isotopes Track Groundwater from Sink to Spring
The hydraulic connection between a sinkhole and a natural spring—the longest and largest yet documented—could help reduce the guesswork in mapping karst aquifers.
Karst Groundwater Contributes to Deformation in Eastern Alps
GPS data show compression and extension strains in the region resulting from changes in aquifer water levels.
