Extracting order from turbulence is difficult, even under the most idealized conditions. A new scaling theory quantifies how eddies influence temperature gradients in geophysical turbulence.
AGU Advances
Himalayan Tectonics in the Driver’s Seat, Not Climate?
Earth’s oscillating climate is a natural guess to explain cyclic patterns in erosion, but new sediment data suggests that cyclicity may emerge from tectonic processes adding material to the Himalaya.
Bottom-up Meets Top-down Estimates of Wetland Methane Emissions
An innovative integration of models and satellite observations indicates weak temperature sensitivity of CH4 emissions from tropical wetlands, but temperature sensitivity is high at higher latitudes.
Subduction Zone Earthquakes: Fast and Slow, Weak and Strong
What causes slow earthquakes in subduction zones? New insights from numerical models suggest that a mixture of strong and weak rocks might be the cause.
Atoll Seismometer Detection of Solitary Ocean Waves
Seismic recordings from the South China Sea indicate that subtle, daily tilting of shorelines due to passing internal ocean waves can be measured on land, promising new constraints on ocean dynamics.
Magnetic Record of Early Nebular Dynamics
Magnetized particles in a meteorite suggest strong magnetic fields in the early solar nebula.
Steady but Slow Progress on the Long Road Towards Gender Parity
The historic disproportionate attrition of women among geoscience faculty is decreasing, but how long will it take to reach gender parity if current trends of progress continue?
Is Earth’s Albedo Symmetric Between the Hemispheres?
The two hemispheres feature the same planetary albedo despite a larger land fraction in the north, because storms over the southern ocean are cloudier than their northern counterparts.
Need for Rational Thinking for Predicting Floods and Droughts
To plan policies that manage flood and drought risk, is it sufficient to follow the science? The better path uses the best science, which draws insight from integrated multidisciplinary research.
Sedimentary Tepees Record Ocean Chemistry
Sedimentary structures from evaporative coastal environments indicate carbonate saturation, offer insight in mid-Mesozoic ocean chemistry and potentially even earlier times.
