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.
Functioning of terrestrial ecosystems is governed by three main factors
Study helps to better assess the capacity of global ecosystems to adapt to climate and environmental change. Ecosystems on Earth’s land surface support multiple functions and services that are critical…
Spring 2020 arctic “ozone hole” likely caused by record-high north pacific sea surface temperatures
Unlike the Antarctic ozone hole that develops annually during austral spring (September, October, and November), Arctic ozone levels usually stay well above the ozone hole threshold. The Arctic stratospheric vortex…
Annual sea ice minimum in the Arctic
Negative trend continues – Comparatively moderate shrinkage of ice extent in 2021. The sea ice extent in the Arctic Ocean reached its annual minimum of 4.81 million square kilometres on…
What lies beneath: Volcanic secrets revealed
Lava samples have revealed a new truth about the geological make-up of the Earth’s crust and could have implications for volcanic eruption early warning systems, a University of Queensland-led study…
Model to predict the angle of repose of sand hills developed
Geophysicists solve a key problem in physics and provide results that can be applied in such diverse areas as planetary research and 3-D printing / publication in ‘PNAS’. The prediction…
Measurement of ice flow from GPS positions logged by short-period seismographs
Seismic instruments generally have a built-in navigation-grade single-mode GPS receiver. During the operation of the station, while recording seismic data, the equipment also records the location of the station at…
Some coral reefs are keeping pace with ocean warming
Surviving corals from past underwater heatwaves may be more tolerant of rising ocean temperatures, providing hope for conservation and restoration of reefs. Some coral communities are becoming more heat tolerant…
Nightmare Without End
Study with participation from Heidelberg shows that supervolcanoes remain dangerous long after erupting. Besides cosmic impacts, supervolcanic eruptions rank among the worst catastrophes in the Earth’s history, like that of…
Studying landslide’s structure by high-frequency receiver functions of local earthquakes
Landslides are recurrent geological phenomena on Earth that cause heavy casualties and property losses annually. While teleseismic receiver functions have been widely used for crust-mantle structure analysis, they have rarely…
A Lunar-based Soft X-ray Imager (LSXI) for the Earth’s magnetosphere
The solar wind-magnetosphere coupling and its dynamic process are the basic driving factors for space weather. To understand its physical connotation, it is necessary to understand the processes of global…
