The mission of this International Polar Year (IPY) project is to uncover secrets of the enigmatic Gamburtsev subglacial mountains that are buried by up to 4 km of ice; to hunt for the oldest ice on our planet; to study subglacial lakes and to discover new clues of past, present and future climate change.
The Gamburtsev subglacial mountains are thought to be the birthplace of the vast East Antarctic Ice Sheet. This project will reveal clues to how the mountains were formed and provide scientists with the best location for future ice core drilling campaigns.
Geophysicist Dr Fausto Ferraccioli of BAS is leading the UK science effort. He says,
“This is both an exciting and challenging project. It is a bit like preparing to go to Mars. Because of IPY, scientists from six countries are working together to do the unthinkable, to explore the deep interior of East Antarctica – one of the last frontier regions of our planet. For two and a half months our international teams will pool their resources and expertise to survey mountains the size of the Alps buried under the ice sheet that currently defy any reasonable geological explanation. At the same time, we will hunt for ice that is more than 1.2 million years old. Locked in this ancient ice is a detailed record of past climate change that will assist in making better predictions for our future.”
Working at high altitude in temperatures of minus 40ºC, science teams will operate from two remote field camps to complete the first major geophysical survey to ‘map’ the mysterious landscape that lies beneath the vast ice sheet.
The science teams will use a range of state-of-the-art technologies to build an unprecedented 3-dimensional view of this secret world. BAS and the US National Science Foundation (NSF) will work together with the German Federal Institute for Geosciences and Natural Resources (BGR) to deploy two survey aircraft, equipped with ice-penetrating radar, gravimeters and magnetic sensors. US, Chinese and Japanese teams will study the deeper structure under the Gamburtsev subglacial mountains using seismology.
Mounting this scientific expedition is an enormous and challenging international effort involving six countries, nine aircraft and two deep-field science camps. All this is supported from US Amundsen-Scott Station at South Pole, McMurdo Research Station, from the Australian Davis Station and the BAS Rothera Research Station. Science and support teams on the Chinese tractor-train from South Pole to Zhongshan Station will sample ice cores and decommission the UK-Australian Camp.
Professor Nicholas Owens, Director of British Antarctic Survey says,
“There’s an amazing history of our planet locked in Antarctica’s ice and rocks. It’s only now that we have the technology to start uncovering the secrets from this unique natural laboratory. This is really big science and it can be done only by working with partners from other national Antarctic programmes. It’s exciting, very demanding in terms of physical hardship and logistics coordination, but this joint effort will yield the kind of information that scientists need to understand our past, present and future climate. In a changing world, with so much uncertainty about our future it is absolutely crucial for society that we find answers to fundamental questions about our Earth.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
