Information is lost when researchers combine statistical models and remote sensing data, but just how much is often unclear. A new study offers a framework to measure the inefficiency.

How Do Turbidity Currents Accelerate?
Flume experiments show that a self-reinforcing cycle can strengthen the currents responsible for transporting large amounts of sediment to the deep oceans.

Leaf-Cutter Ants Boost Carbon Dioxide Emissions from Soil
Leaf-cutter ant nest openings emit up to 100,000 times more carbon dioxide than surrounding soil, a new study shows.

Regional Metamorphism Occurs Before Continents Collide
Evidence from collision zones suggests that the high temperatures that create regional zones of metamorphic minerals occur in wide, hot back arcs prior to continental collision deformation.

Organic Particles Affect Carbon Cycling in Boreal Waters
Dissolved organic carbon receives much of the focus in aquatic research, but a new study suggests that bulkier particulate matter may play a significant role in regulating carbon dioxide emissions.

In a Submarine Trough, Permeable Rocks May Lead to Quakes
In Japan’s submarine Nankai Trough, rock permeability is much higher when measured at larger scales, likely because of big fractures and faults that are not captured at small scales.

Tool to Capture Marine Biological Activity Gets Coastal Upgrade
Upwelling hinders an efficient method to estimate a key measure of biological productivity in coastal waters, but accounting for surface temperatures could boost accuracy.

Satellite Observations Validate Stratosphere Temperature Models
Since the 1970s, the stratosphere has cooled as ozone levels dropped and carbon dioxide levels increased. Chemical models of the temperature decline conflicted with satellite observations—until now.
