Fresh approaches to processing GRACE data

To document large-scale transformations on Earth, such as waning ice sheets and shifting coastlines, geoscientists often use views from space to track mass changes on daily to decadal timescales.

On icy moon Enceladus, expansion cracks let inner ocean boil out

In 2006, the Cassini spacecraft recorded geyser curtains shooting forth from "tiger stripe" fissures near the south pole of Saturn's moon Enceladus—sometimes as much as 200 kilograms of water per second. A new study suggests ...

Satellites' lasers reveal changes in Earth's water movement

Understanding climate change and its effects on humans, animals, and natural spaces requires studying Earth as a whole, interconnected system. Water movement on Earth, in particular, is a process that affects everything from ...

Coastal aquaculture can reduce nutrient transport

Coastal aquaculture produces many types of seafood, including fish, shellfish, and aquatic plants. An ongoing challenge, however, is understanding the impact of excessive aquaculture on nutrient levels in the surrounding ...

Biological crusts affected by drought can still stabilize soils

Biological soil crusts are communities of cyanobacteria, fungi, lichens, and other living organisms that can bind grains together and reduce the susceptibility of soils to erosion by water or wind. Crusts dominated by cyanobacteria, ...

As oceans warm, marine cold spells are disappearing

Marine cold spells are cold versions of heat waves: periods of exceptionally cold water, able to hurt or help the ecosystems they hit. As the atmosphere and oceans warm, marine cold spells are becoming less intense and less ...
