Huge and rapid subsurface temperature changes associated with propagating internal solitary waves were observed from a moored coastal acoustic tomography (CAT) system in Lombok Strait in Indonesia.Read More �
Integration of sustainable marine and freshwater aquaculture with terrestrial agriculture will be necessary for meeting Earth’s future food requirements.Read More �
Numerical simulations of earthquake cycle deformation reveal that co-seismic and interseismic fault propagation can produce distinct propagation angles that may be recorded in the crust.Read More �
A laboratory study assesses thermochemical remanence as a reliable paleointensity recorder, which could open new venues for studying Earth’s ancient magnetic field.Read More �
Getting the polar stratosphere right is critical in the simulation of North Atlantic climate change, which is shaped by the interaction of Arctic Amplification and tropical upper tropospheric warming.Read More �
The first in-situ ion observations from NASA’s Juno spacecraft reveal the surprising, simultaneous presence of cold protons and hot oxygen and sulfur ions in the high-latitude ionosphere of Jupiter.Read More �
New research using a highly complete earthquake catalog shows that 72% of M4+ mainshocks are preceded by foreshocks, implying that foreshock activity is much more prevalent than previously thought.Read More �
A new tool for tracking coronal mass ejections away from the Sun opens a path toward more accurate warnings for operators who have to cope with adverse space weather.Read More �
Silicate melts containing H2O in the lowermost mantle are surprisingly dense and may stagnate there, trapping primordial volatiles and potentially causing some of the ultra-low velocity zones.Read More �
A Japanese satellite reveals rapid and surprisingly frequent transport of molecular ions from the ionosphere to the magnetosphere, under not only extreme but also moderate geomagnetic conditions.Read More �
