29.08.2013 | CO2 injection at the Ketzin pilot site successfully finalized after five years

CO2 injection at the Ketzin pilot site successfully finalized after five years
29.08.2013|Potsdam/ Ketzin: As from today, August 29, 2013, the GFZ German Research Centre for Geosciences terminates the injection of carbon dioxide (CO2) near the town Ketzin/Havel in the State of Brandenburg after about five years of operation. At this pilot site for the scientific investigation of the geological storage of the greenhouse gas CO2, in total 67,271 tons were injected into a salt-water bearing sandstone in a depth of 630 to 650 meters since June 2008.

Earthquakes and Tectonics in Pamir Tien Shan
27.08.2013|Potsdam: Earthquake damage to buildings is mainly due to the existing shear waves which transfer their energy during an earthquake to the houses. These shear waves are significantly influenced by the underground and the topography of the surrounding area. Detailed knowledge of the landform and the near-surface underground structure is, therefore, an important prerequisite for a local seismic hazard assessment and for the evaluation of the ground-effect, which can strongly modify and increase local ground motion.

High precision laboratories in the network
20.08.2013|Potsdam: At the GFZ German Research Centre for Geosciences, the new secondary ion mass spectrometer (SIMS) is being going into operation. This machine costs 3.6 million Euros and is about 10 times faster and five times more accurate in the measurement of geologically important chemical systems than its predecessor. Secondary ion mass spectrometry is one of the most important micro-analytical methods in the geosciences for investigating isotopic and trace element compositions. The achieved detection limit is enormous: From unimaginably small samples on the order of billionths of a gram, SIMS locates a single atom among ten million other atoms. The tiniest traces of precious metals, for example, can therefore be determined, with which the formation of ore deposits can be explored.

| Extreme weather, climate and the carbon cycle

Extreme weather, climate and the carbon cycle
14.08.2013|Potsdam: Extreme weather and climate events like storms, heavy precipitation and droughts and heat waves prevent the update of 3 giga-tonnes of carbon by the global vegetation. A team of scientists under the lead of Markus Reichstein, Director of the Max Planck Institute for Biogeochemistry in Jena, Germany, investigated the effect of extremes on the carbon cycle from the terrestrial ecosystem perspective for the first time. In the current issue of Nature (14th of August 2013), they use Earth observation methods and numerical models to show that especially extreme droughts lead to a strong reduction in the carbon sequestration of forests, grass- and croplands. This reduction in the regional and global carbon uptake has the potential to influence the global climate. Especially large scale events like the heat wave in western and southern Europe in the year 2003 provide the evidence that such extremes events have a much stronger and long lasting impact on the carbon cycle than expected so far.

| Greenland ice is melting - even from below

Greenland ice is melting - even from below
07.08.2013|Potsdam: The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, there is an increased heat flow from the mantle and a complex interplay between this geothermal heating and the Greenland ice sheet. The international research initiative IceGeoHeat led by the GFZ German Research Centre for Geosciences establishes in the current online issue of Nature Geosciences (Vol 6, August 11, 2013) that this effect cannot be neglected when modeling the ice sheet as part of a climate study.

26.07.2013 | IASPEI würdigt NMSOP-2 (only available in German)

Auf ihrer 2013 Scientific Assembly in Göteborg, Schweden würdigte die International Association of Seismology and Physics of the Earth's Interior (IASPEI) die Bedeutung des "New Manual of Seismological Observatory Practice (NMSOP-2)" für Ausbildung und Methodik in Observatorien. Sie drückte dem Deutschen GeoForschungsZentrum GFZ ihre Wertschätzung für das Hosting und der Pflege dieser "unschätzbaren Ressource" auf unserer Website aus. Der Dank gilt insbesondere Prof. em.Dr. Peter Bormann (GFZ) für die Erstellung des Manuals.
