A new method for observing water within ice has revealed stored meltwater that may explain the complex flow behavior of some Greenland glaciers, an important component for predicting sea-level rise in a changing climate.
Researchers from Tokyo Metropolitan University have applied machine-learning techniques to achieve fast, accurate estimates of local geomagnetic fields using data taken at multiple observation points, potentially allowing detection of changes caused by earthquakes and tsunamis. A deep neural network (DNN) model was developed and trained using existing data; the result is a fast, efficient method for estimating magnetic fields for unprecedentedly early detection of natural disasters. This is vital for developing effective warning systems that might help reduce casualties and widespread damage.
Eruption patterns in a New Zealand volcanic system reveal how the movement of magma rising through the crust leads to smaller, more frequent eruptions.
A recently published study led by researchers at the University of Hawai'i at Manoa School of Ocean and Earth Science and Technology reveals Ganymede, an icy moon of Jupiter, appears to have undergone complex periods of geologic activity, specifically strike-slip tectonism, as is seen in Earth's San Andreas fault.
This problem is one of the still unresolved questions of the current standard description of the Big Bang. Different nuclear reactions responsible for the creation and destruction of atomic nuclei in the nucleosynthesis during the Big Bang are crucial in the determining the primordial abundance of lithium, the third (and last) chemical element formed during the very early phase of the creation of the universe.
Now everyone can become co-creator and co-user of the largest detector of cosmic ray particles in history - as well as a potential co-discoverer. All you need is a smartphone and the CREDO Detector application turned on overnight. Under development for over two years, the CREDO project is entering the era of its maturity. Today, at IFJ PAN in Cracow, the first light of the detector was presented collected by the smartphones of project participants from around 20 countries.
Researchers from CU Boulder report that they may have pinned down the cause of 'stagnant slabs,' which resemble a wrench in the engine of the planet.
The Coriolis effect impacts global patterns and currents, and its magnitude, relative to the magnitude of inertial forces, is expressed by the Rossby number. For over 100 years, scientists have believed that the higher this number, the less likely Coriolis effect influences oceanic or atmospheric events. Recently, however, researchers found that smaller ocean disturbances with high Rossby numbers are influenced by the Coriolis effect. Their discovery challenges assumptions of theoretical oceanography and geophysical fluid dynamics.
Radical solutions to climate change might save lives, but a commentary in the October 2018 issue of the journal Nature Climate Change calls for caution because geoengineering still lacks a 'clean bill of health.'
A team from Siberian Federal University (SFU) together with their colleagues from the Institute of Computational Modeling of SB RAS presented a calculation describing the structure of flows and evaporation processes in the two-layer system with liquid-gas vapor mixture.
