Coastal hurricanes 🌊🌪️in the US projected to grow stronger, especially as warming continues 📈🌡️, according to a new study led by @PNNLab . Read the piece by @Newsweek to learn more: newsweek.com/destructive-hur…

Warning as US may face "more destructive" hurricanes

Researchers discovered that in 20 years since 2000, hurricanes intensified by 1.15 knots every six hours.

Meanders are ubiquitous features that regulate water quality along rivers. We explored their hydrodynamics and potential to act as net nitrate sources or sinks. Our insights are critical to river corridor science and can guide river restoration strategies. agupubs.onlinelibrary.wiley.…

How do river meanders affect exchange flows and biogeochemistry? One interesting finding: Meander necks in high-sinuosity channels shield the effect of regional groundwater fluxes, resulting in persistent hyporheic zones. #PNNLRCSFA @PNNLab agupubs.onlinelibrary.wiley.…
