26.08.2014 | A high-resolution bedrock map for the Antarctic Peninsula

26.08.2014: Antarctic glaciers respond sensitively to changes in the Atmosphere/Ocean System. Assessing and projecting the dynamic response of glaciers on the Antarctic Peninsula to changed atmospheric and oceanic forcing requires high-resolution ice thickness data as an essential geometric constraint for ice flow models. Therefore, a Swiss-German team of scientists developed a complete bedrock data set for the Antarctic Peninsula on a 100 m grid. They calculated the spatial distribution  of ice thickness based on surface topography and ice dynamic modelling.

22.08.2014 | Volcanic eruptions and tree growth

22.08.2014:Large volcanic eruptions can influence the climate from years to decades. Recently, scientists from the GFZ German Research Centre for Geosciences investigated the effects of large volcanic eruptions on tree growth. Based on tree-ring analysis they found a decreased growth in close to 60 percent of the examined trees over a period of four years after strong volcanic eruptions. However, positive growth responses were also identified in 32 percent of the trees. Furthermore this effect was less pronounced in central European lowlands compared to trees at altitudinal and alpine timberline sites.

14.08.2014 | Gorges are eradicated by downstream sweep erosion

17.08.2014: Local surface uplift can block rivers, particularly in mountainous regions. The impounded water, however, always finds its way downstream, often cutting a narrow gorge into the rocks. Subsequent erosion of the rocks can lead to a complete eradication of this initial incision. A team of scientists from the GFZ German Research Centre for Geosciences has now revealed a new mechanism that drives this process of fluvial erosion.

29.07.2014 | Foreshock series controls earthquake rupture

13.08.2014|Potsdam: A long lasting foreshock series controlled the rupture process of this year’s great earthquake near Iquique in northern Chile. The earthquake was heralded by a three quarter year long foreshock series of ever increasing magnitudes culminating in a Mw 6.7 event two weeks before the mainshock. The mainshock (magnitude 8.1) finally broke on April 1st a central piece out of the most important seismic gap along the South American subduction zone. An international research team under leadership of the GFZ German Research Centre for Geosciences now revealed that the Iquique earthquake occurred in a region where the two colliding tectonic plates where only partly locked.

23.07.2014 | Microbiological samples from GFZ in the International Space Station (ISS)

23.07.2014: Researchers at the GFZ will send microbiological samples from Siberian permafrost to the International Space Station (ISS) as part of the Biology and Mars Experiment (BIOMEX). This interdisciplinary project of the European Space Agency (ESA) was launched on 23 July 2014.
