Deep tree roots bring respiring microbes into broken bedrock, generating carbon that’s released into the environment. New research explores this oft-overlooked carbon source.Read More »Geology & Geophysics
Scientists are using a variety of geochemical, geophysical, and numerical methods to study offshore freshened groundwater and better understand its role in the global water cycle.Read More »Climate Change
Around 200 years ago, when conversion of land for agriculture became more widespread, the amount of sediment accumulating in riverbeds across the continent jumped tenfold.Read More »
Although Venus does not have plate tectonics today, previous episodes of intense tectonic activity could have resulted in a distribution of crustal thickness and age resembling the plate we see today.Read More »Hydrology, Cryosphere & Earth Surface
By systematically turning valves off and on in water distribution networks, researchers can locate pipe leaks, which could help to save huge quantities of drinking water.Read More »Hydrology, Cryosphere & Earth Surface
Researchers peer into precipitation partitioning—the process by which plants and the organic matter coating them help shape the hydrologic cycle.Read More »Climate Change
Landscapes will respond to hydroclimatic changes associated with modern global warming, such as increasing extreme storms and wildfire, but to what extent is physical landscape change already evident?Read More »
