A new model quantifies the relative contributions of denitrification and other processes of nitrogen uptake, such as by plants, from groundwater in riparian areas around streams.
Modeling
Understanding Material Movement in the Ocean’s Upper Layer
Computer simulations are advancing our understanding of how natural and anthropogenic materials are transported around the upper layer of the ocean.
Stored Nutrients and Climate Warming Will Feed More Algal Blooms
High nutrient concentrations cause water quality problems in lakes, and as the climate warms, these issues will only get worse. A new model assesses future scenarios and explores solutions.
Pinpointing Emission Sources from Space
Satellite data combined with wind models bring scientists one step closer to being able to monitor air pollution from space.
Observational Data Validate Models of Sun’s Influence on Earth
Using a combination of independent models and observations over multiple timescales, scientists verify two important models that gauge the amount of solar radiation Earth receives.
Hackathon Speeds Progress Toward Climate Model Collaboration
Climate scientists collaborated in a nationwide event to analyze and compare archived Earth system model simulations and to generate input for the IPCC’s upcoming climate change report.
Heat Waves Born of Earth and Sky
Researchers use computer simulations to uncover the significant contributions that dry soil and atmospheric wind patterns make to major heat waves.
What Lies Beneath Is Important for Ice Sheets
New research reconstructing the topography of Antarctica shows that the continent has 25% less land above sea level than when ice first started to accumulate 34 million years ago.
Finding Faults in Our Past: Uncovering the Messina Earthquake
The source of the deadly 1908 Italian earthquake may finally be identified, thanks to a fresh look at the geomorphology of the Strait of Messina.
Hydropower and Bugs
Alpine hydropower plants commonly flush sediment that accumulates at intakes, but the associated rapid rise in discharge, turbidity, and streambed instability put aquatic insects at risk.
