Researchers Saikiran Tharimena, Catherine Rychert and Nicholas Harmon at the University of Southampton have published exciting results in the journal Science about the thickness of the continents and the defining mechanism of the tectonic plate. The thickness of the continental portion of Earth’s cold and rigid plates is a source of debate. Previous attempts to measure… Read More How thick are the continents?
A team of seismologists from the University of Southampton are currently on board the Royal Research Ship Discovery sailing across the Mid-Atlantic Ocean. They are out for the second phase of the PI-LAB (Passive Imaging of the Lithosphere-Asthenosphere Boundary) project, this time recovering ocean bottom stations that were deployed last year. Their scientific mission is… Read More PI-LAB phase II: The recovery
By PhD students Aude Lavayssiere and Finn Illsley-Kemp. As part of the RiftVolc project aiming to understand magmatism and rifting in the East African Rift System, Dr Derek Keir and two PhD students, Finn Illsley-Kemp and Aude Lavayssiere, went to Ethiopia last month to deploy seismic stations. RiftVolc is a project that started in September… Read More Seismic deployment in the Main Ethiopian Rift
Stretchy Slabs in Deep Earth A new paper out in Nature Geoscience, led by Caroline Eakin, suggests that subducting slabs may not be as strong as we think, but instead may be relatively weak and deform easily. When new oceanic plates form at mid-ocean ridges it is thought that they “freeze-in” a certain crystal fabric… Read More Stretchy Slabs in Deep Earth
Bedanta Goswami, and colleagues from G&G and Ifremer (France) have published a new research article in Journal of Geophysical Research: Solid Earth entitled “A joint electromagnetic and seismic study of an active pockmark within the hydrate stability field at the Vestnesa Ridge, West Svalbard margin”. Gas hydrates are ice-like crystals with a molecule of gas occupying the… Read More First joint electromagnetic and seismic investigation of gas hydrates, offshore Svalbard

At the end of 2014, a number of the Geology and Geophysics Research Group made the annual migration to San Francisco for the American Geophysical Union fall meeting. With nearly 24,000 attendees, and 23,000 poster and oral presentations, AGU is the world’s largest Earth and Space science meeting, providing an excellent stage to communicate and… Read More Strong presence by G&G Group at the American Geophysical Union (AGU) fall meeting
Melis Cevatoglu and John Davis had a successful cruise in Ardmucknish Bay (Oban, Scotland) on board R/V Seol Mara, on 23 and 24 April 2014, under the scope of the QICS Experiment (Quantifying and Monitoring Potential Ecosystem Impacts of Geological Carbon Storage). QICS experiment, funded by the Natural Environment Research Council of the UK, with… Read More Return to Ardmucknish Bay – is the CO2 still in the sub-surface?
A workshop on the structure and dynamics of the lithosphere-asthenosphere system was organized at the College de France, Paris, from 19-20 November 2013. The primary focus of the workshop was to enhance understanding of the dynamics interaction between the colder, more brittle lithosphere and the warmer, more ductile asthenosphere by combining constraints from observations and… Read More Understanding the structure and dynamics of the lithosphere-asthenosphere system
