Could AI Be Useful for Arctic Communities Facing Sea Ice Loss?
The forecasting tool IceNet promises to be a useful tool for evaluating sea ice loss in the Arctic. But ethical and logistic considerations have to be taken before scientific and Indigenous communities start working together.
Roadside Ditches Are Effective at Nitrogen Removal
Researchers compared the nitrogen removal potential by microbes in ditches that drained forested, urban, and agricultural lands and discovered that roadside ditches are important areas for removing nutrients.
NEON Lights a Path for Sustained Ecological Observations
Resources and data offered by the National Ecological Observatory Network are supporting researchers investigating critical ecosystem changes across the country.
Gulf Stream Intrusions Feed Diatom Hot Spots
Previous research suggested that the intrusion of low-nutrient Gulf Stream water into the Mid-Atlantic Bight would reduce productivity, but a new study finds that it can also lead to chlorophyll hot spots.
Amazon Forests Are Turning into Savannas
Floodplain forests have low resilience to repeated exposure to wildfires. As climate change increases the instances of fires, forests may transform to less productive grassland ecosystems.
First Worldwide View of a Key Phytoplankton Proxy
New insights into the dynamics of ocean features known as deep chlorophyll maxima set the stage for better understanding of their role in carbon cycling.
Years After the Pacific Marine Heat Wave, Ecosystem Shifts Persist
Researchers question whether Gulf of Alaska species will return to pre–heat wave conditions.
Sediment Mismanagement Puts Reservoirs and Ecosystems at Risk
Current regulations and reservoir management practices impede efforts to deal with sediment accumulation behind U.S. dams. New approaches are needed to improve reservoir sustainability.
