This work, carried put in the Dpt. of Geodynamics of the University of Granada (Universidad de Granada, [http://www.ugr.es]) and the Andalusian Institute of Earth Sciences, has given rise, for the time being, to four publications in prestigious international scientific journals. “Intense earthquakes can be registered in the area, reaching 7 degrees in the Richter scale, whose tectonic content is similar to that of other densely populated regions of the planet, like the San Andreas Fault (California, United States), the Caribbean arc or Japan”, Bohoyo points out.
Working on the ground is quite difficult. ”The campaign is brought up in Granada in detail, but once there the climatic conditions and the enormous ice blocks limit the possibilities, leaving wide unexplored sectors”, the young scientist says. Expeditions take place on board the Hespérides, ceded to the CSIC (Higher Council of Scientific Research) and crewed by the staff of the Spanish Ministry of Defence.
“The main objective is to study tectonic blocks´ fragmentation and evolution”, Professor Jesús Galindo Zaldívar explains, who is one of the persons in charge for the work, together with Andrés Maldonado López. With data of different scientific nature, researchers from Granada have obtained a map of the morphology and tectonic evolution of the area; thanks to them it has been possible to determine the expansion age of the Scotia Sea oceanic bowls. Galindo adds that “it is a continental crust area that formed a barrier between the Atlantic and the Pacific, between South America and the Antarctic Peninsula, thirty million years ago”.
Circumpolar antarctic current
The opening of this big barrier that connects the two oceans, gave rise to a circumpolar current that, at the present day, influences in a determinant way the planet´s climatology. It is the most important current in Antactica, which connects with others, isolating the anctartic continent. In fact, its existence is one of the keys of the extremely cold anctartic climate and one of the most important international scientific lines at present.
The scientific dimension of this group of the University of Granada is very relevant. Last week (the last week of August), Galindo and Bohoyo were present in the biannual meeting of the SCAR (Scientific Committee on Antarctic Research) in Bremen (Germany). This International Scientific Committee concentrates a total of 28 countries involved in the scientific knowledge of the Antarctica.
Before the work of the researchers from Granada, there were hardly a few scarcely systematized data about the Scotia Arc, from British expeditions in the seventies. As a matter of fact, Fernando Bohoyo goes to the British Antarctic Center, one of the international reference centres on the subject, at the end of this week, to go deeply into data on the external part of the tectonic arc and the northern part of the Scotia Sea. In December, they will go back to the Antarctica to collect more data and continue with this promising scientific study.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
