Scientists funded through the Natural Environment Research Council’s (NERC) Ocean Margins LINK programme are helping to plug the gap in knowledge about these ocean margins. Using satellite technology, digital mapping and seismic surveys, they have developed computer models that reveal the structure, composition and evolution of the boundary between continents and oceans.
Study of the boundaries shows how continental basins form, accumulating sediments that eventually provide ideal conditions for oil and gas to collect. The resulting data and models from the programme are a prime example of how academic and industry goals can complement each other.
Richard Hardman, Chairman of the Ocean Margins LINK programme committee, said, “We have achieved new, world class science which would never have happened without this initiative. Furthermore the benefits continue. Work groups have been formed, alliances generated and scientific problem solving is under way – and is unlikely to end with the programme. I think many companies have been surprised at the value of the work done and its application to practical problems.”
One of the projects within the Ocean Margins LINK programme tackled a major problem facing the oil and gas industry. Conventional techniques used to locate oil and gas reserves in the Atlantic Ocean margins are unable to ‘see’ through the thick layers of basalt left by volcanic activity millions of years ago. The project team developed the Integrated Seismic Imaging and Modelling of Margins (iSIMM) system and from that created a commercial model. The model is such a large improvement on earlier techniques that it is already in use by the hydrocarbon industry.
In another project, researchers have found that some of the same revolutionary techniques for oil exploration can also being used to detect the use of illegal steroids in horse racing and athletics. A technique called hydropyrolysis, which breaks down samples for analyses in a very selective manner, can solve problems where conventional analysis fails – such as in reconstructing the history of a particular petroleum basin to determine whether it’s worth drilling. The same methods of analysis can detect the illicit use of steroids. Work continues to explore the commercial possibilities for both uses.
These and some of the other projects carried out under the Ocean Margins LINK programme will be discussed at a conference at the Royal Society in London on Thursday 15 February.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
