Deep sea reveals linkage between earthquake and carbon cycle
Deep sea reveals linkage between earthquake and carbon cycle
In order to understand the global carbon cycle, deep-sea exploration is essential, an international team led by geologists from Innsbruck concludes. For the first time, they succeeded in quantifying the amount of organic carbon transported into the deep sea by a single tectonic event, the giant Tohoku-oki earthquake in 2011.

Climate change: US desert areas to become even drier
Climate change: US desert areas to become even drier
350,000 years of climate history hidden in Devils Hole cave: Geologists from the University of Innsbruck study rainfall patterns in the distant past to better understand how deserts in the southwest United States will be impacted by future climate change. Beneath the Amargosa desert of the southwest United States lies a hidden gem for climate research.

What's 'up' in space?
What’s ’up’ in space?
The International Astronomical Union has agreed on a new reference frame for directions in space. TU Wien played an important role in developing this new frame. In future, when spacecrafts are sent to other planets or when the rotation of planet Earth is studied, a new reference frame will be used. On 30 August, at the General Meeting of the International Astronomical Union (IAU) in Vienna, the new international celestial reference frame ICRF3 was adopted, allowing for more precise directional specifications in space.

Giant earthquakes: not as random as thought
Giant earthquakes: not as random as thought
Mud stories provide new insights in the seismic hazard along the Chilean subduction zone By analyzing sediment cores from Chilean lakes, an international team of scientists discovered that giant earthquakes reoccur with relatively regular intervals. When also taking into account smaller earthquakes, the repeat interval becomes increasingly more irregular to a level where earthquakes happen randomly in time.

Human Contribution to Glacier Mass Loss on the Increase
Human Contribution to Glacier Mass Loss on the Increase
By combining climate and glacier models, scientists headed by Ben Marzeion from the University of Innsbruck have found unambiguous evidence for anthropogenic glacier mass loss in recent decades. In a paper published in Science, the researchers report that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes.

Amber Provides New Insights Into the Earth's Atmosphere
Amber Provides New Insights Into the Earth’s Atmosphere
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant resins. The results suggest that atmospheric oxygen was considerably lower in the Earth's geological past than previously assumed.

Global warming will raise sea levels for centuries
Global warming will raise sea levels for centuries
Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of the ocean and melting mountain glaciers are the most important factors causing sea-level change today, the Greenland and Antarctic ice sheets will be the dominant contributors within the next two millennia, according to the findings.

Glaciers Contribute One Third to Sea Level Rise
Glaciers Contribute One Third to Sea Level Rise
Ninety-nine percent of all of Earth's land ice is locked up in the massive Greenland and Antarctic ice sheets. However, over the period 2003 to 2009, the melting of the world's other land ice stored in glaciers contributed just as much to sea level rise as the two ice sheets combined. This is the result of a new study led by Alex Gardner from Clark University (USA), which has been published in the current issue of the journal Science.

Climate Change: Water Reservoir Glacier
Innsbruck climatologists demand a differentiated discussion Glaciers of large mountain regions contribute, to some extent considerably, to the water supply of certain populated areas. However, in a recent study conducted by Innsbruck glaciologists and climatologists it has been shown that there are important regional differences.

Earthquake in Chile causes days to be longer
Since the earthquake in Chile in February 2010, the "Höhere Geodäsie" [Advanced Geodesy] research group at the Institute of Geodesy and Geophysics at the Vienna University of Technology (TU Vienna) has been helping measure the earth on a global scale. First results indicate that the rotational speed of the earth has become marginally slower and days have become longer by 0.3 microseconds.

The ever-changing Earth
Researchers at the Institute of Geodesy and Geophysics at Vienna University of Technology (TU) are investigating the effects of the Earth's atmosphere on our planet's shape, its rotation and its gravitational field. The Earth's atmosphere is not only essential to support human life on Earth; it also affects our planet's shape, its rotation and its gravitational field.
