Wildfire smoke may have amplified Arctic phytoplankton bloom

Smoke from a Siberian wildfire may have transported enough nitrogen to parts of the Arctic Ocean to amplify a phytoplankton bloom, according to new research from North Carolina State University and the International Research ...

What lies beneath melting glaciers and thawing permafrost?

Around the planet, ice is rapidly disappearing. From mountain tops, the poles, the seas, and the tundra. As the ice melts, it's exposing new surfaces, new opportunities, and new threats—including valuable mineral deposits, ...

Are we missing a crucial component of sea-level rise?

Recent efforts using computational modeling to understand how melting ice in Antarctica will impact the planet's oceans have focused on ice-sheet geometry, fracture, and surface melting—processes that could potentially ...

Arctic lakes are vanishing in surprise climate finding

The Arctic is no stranger to loss. As the region warms nearly four times faster than the rest of the world, glaciers collapse, wildlife suffers and habitats continue to disappear at a record pace.

Investigating the dynamics that reshape permafrost environments

When permafrost thaws, water can flow more quickly through the ground, creating a complex subsurface flow system. Researchers at the Barrow Environmental Observatory in Alaska gained insight into this process by taking daily ...

Researchers use bacteria to enhance concrete resistance

Concrete, with its low cost, good compressive strength, and manufacturing convenience, is one of the most widely used materials in construction. However, with accelerating urbanization, natural aggregates for mixing with ...

Trees wearing accelerometers help track snowstorms

Knowing how tree canopies affect snowpack is a key part of predicting water availability. Despite this importance, hydrologists are still working to accurately quantify how snow "intercepted" by tree canopies affects snowpack. ...
