Envisioning a Near-Surface Geophysics Center for Convergent Science
A recent effort identified how a proposed near-surface geophysics center integrating research and teaching could address critical challenges and promote community engagement and cultural change.
Grains of Sand: Too Much and Never Enough
Sand is a foundational element of our cities, our homes, our landscapes and seascapes. How we will interact with the material in the future, however, is less certain.
Deploying Community Water Solutions with People, for People
Guiding principles and strategies for solving local water availability problems in India have emerged from collaborations involving water users, water experts, and water solutions providers.
Why is Permafrost Groundwater Surfacing?
Hydrogeological properties of degrading permafrost come to fruition with a new 3-D modeling study that highlights the increasing role of groundwater in the water cycle of high-latitude areas.
Cuando los ríos están contaminados, las inundaciones son solamente el primer problema
A medida que las inundaciones aumentan en frecuencia e intensidad, los productos químicos enterrados en los sedimentos de los ríos se convierten en “bombas de tiempo” que esperan activarse.
Lake Michigan’s Salinity Is on the Rise
Road salt is primarily to blame for the shift, though the water remains within safe levels for now.
From River to Sea: Estimating Wood Cascades
Dams and deforestation have chipped away at the millions of cubic meters of wood that flow through rivers and out to sea.
Satellites Spy on Sand Mining in the Mekong
Concrete, used in everything from streets to skyscrapers, needs sand, often mined from active rivers in developing countries with little oversight. Researchers can now use satellites to keep watch.
Water Quality Policy Must Consider Stored Watershed Phosphorous
Phosphorous stored in watersheds and affects water quality for decades. A new model predicts phosphorus accumulation and depletion, and the consequences for water quality conservation measures.
