Polar Scientists Will Reveal 50 Million Years Of Climate History

26.07.2004


Invitation to a press conference for the start of the Integrated Ocean Drilling Program’s Arctic Coring Expedition, ACEX, on board the icebreaker Oden in the port of Tromsø, Norway on Friday 6 August 2004 at 11.00



Three icebreakers will carry a team of international scientists to the Arctic Ocean next month (8 August), to study its geological history. The Arctic Coring Expedition, ACEX, aims to reach several hundreds of metres into the sediments of the Lomonosov Ridge, an underwater mountain chain, which contain millions of years of climate history. No operation on this scale has ever before been attempted by scientists in such a hostile environment and the project has the highest scientific priority.

By analysing samples from the 500 metre-thick sediment on top of the ridge scientists will reconstruct the climatic and environmental history of the Arctic. The Arctic plays a fundamental role to the climate and the complexity of this basin can only be examined by direct sampling of sediments.


Climate change, from hothouse to icehouse, and the cause of this change is vigorously debated among scientists and the ACEX team will make a valuable contribution to the discussions by revealing the long-term history of Arctic sea ice.

The Lomonosov Ridge, about 1000 metres under the sea-surface, located at 88°N about 250 kilometres from the North Pole. The expedition will return after six weeks, in mid-September, and later during the year the analysing work will start at Bremen University in Germany.

ACEX is a very complex mission and the operational plan includes three icebreakers; the Swedish registered Vidar Viking which will serve as the coring vessel, the Swedish icebreaker Oden which will be a “protection shield” as well as the operational HQ and the Russian icebreaker Sovetskiy Soyuz will be the main icebreaker. As the Arctic weather and ice conditions can be very harsh it is a great challenge to keep the vessel-mounted rig stationary while it retrieves cores from the seabed below.

Im Focus: Making lightweight construction suitable for series production

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...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

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...

Im Focus: Deep inside Galaxy M87

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...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

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...
