Observations reveal a connection between auroral particle precipitation and scintillation, indicating that the ionospheric E-region is a key source region for phase scintillation at auroral latitudes.

Sedimentary Tepees Record Ocean Chemistry
Sedimentary structures from evaporative coastal environments indicate carbonate saturation, offer insight in mid-Mesozoic ocean chemistry and potentially even earlier times.
Satellite Data Reveal Magnetospause K-H Waves Impact Auroras
Analysis of multiple satellite data has revealed a striking connection between K-H waves on the magnetopause, surface waves in the hot zone near the plasmapause, and auroral undulations.
The Great Unconformities?
New thermochronology data and thermal history modeling from the Canadian Shield show that the Great Unconformity formed there later than elsewhere in North America and may represent another event.
Tropical Cyclone Induced Increase in Ocean Primary Production
A positive trend in tropical cyclone induced ocean mixing and primary production is compensating the overall decline in global primary production due to anthropogenic climate change.
Unravelling Sands and Muds Suspended in Coastal Environments
A new study uses the response of optical and acoustic measurements to derive a sediment composition index for prediction of the relative fractions of mixed sediments in suspension.
Analysis Reveals Patterns of Streamflow Generation Across USA
A new study transforms a classic conceptual framework into a quantitative classification of streamflow generation patterns.
Permanence of Nature-Based Climate Solutions at Risk
Conserving native ecosystems helps sequester carbon and mitigate climate change, but new statistical modeling questions the permanence of California’s carbon-rich forests with climate change.
The Highs and the Lows of Megathrust Earthquakes
Why does low-frequency energy come from the shallow part of ruptures, and the high frequencies from deep?
Reconstructing Rocks with Machine Learning
Machine learning can be used to accurately reconstruct high-resolution, 3D images of rocks from 2D cross-sections, which opens the door to more detailed simulations.
