Earth Sciences

Earth Sciences (also referred to as Geosciences), which deals with basic issues surrounding our planet, plays a vital role in the area of energy and raw materials supply.

Earth Sciences comprises subjects such as geology, geography, geological informatics, paleontology, mineralogy, petrography, crystallography, geophysics, geodesy, glaciology, cartography, photogrammetry, meteorology and seismology, early-warning systems, earthquake research and polar research.

No glacial fertilization effect in the Antarctic Ocean

International study led by the University of Bonn records 1.5 million years of climate in the drill core. Changes in the concentration of atmospheric carbon dioxide (CO2) are considered to…

Smallest earthquakes ever detected in micron-scale metals

On the micrometer scale deformation properties of metals change profoundly: the smooth and continuous behaviour of bulk materials often becomes jerky due to random strain bursts of various sizes. On…

A swarm of 85,000 earthquakes at the Antarctic Orca submarine volcano

In a remote area, a mix of geophysical methods identifies magma transfer below the seafloor as the cause. Volcanoes can be found even off the coast of Antarctica. At the…

Making the drinking water supply climate-proof

The research network “TrinkXtrem” wants to improve the forecast quality of groundwater models during extreme weather events. Ensuring the supply of drinking water during extreme weather events such as a…

Artificial modification of Earth’s radiation belts

… by ground-based very-low-frequency (VLF) transmitters. Narrow-band VLF transmitter waves originate from the powerful ground-based VLF transmitters for submarine communications, which are typically over the frequency range of 10–30 kHz….

Ancient helium leaking from core offers clues of Earth’s formation

Vast stores of helium from the Big Bang lingering in the core suggest Earth formed inside a solar nebula. Helium-3, a rare isotope of helium gas, is leaking out of…
