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
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
Southampton Geologists and Geophysicists, along with colleagues in the UK, Greece, the rest of Europe and the US, have been working in the active Corinth rift in Greece for the last 10-15 years – this is one of the most seismically active areas of Europe and one of the most rapidly extending regions on Earth.… Read More Progress on Future Drilling in the Active Corinth Rift, Greece

Starting September 2014, PhD student Chen Chen and post-docs Louise Watremez and Manel Prada (DIAS, Dublin) are working together to define the crustal structure across Porcupine Basin, which is located offshore SW Ireland. The degree of crustal thinning increases from North to South, allowing us to observe the structures of the crustal thinning at different… Read More The Porcupine Basin project
PhD students Ryan Gallacher and Finn Illsley-Kemp have recently completed a two week trip to Lake Tanganyika in Tanzania. They were performing a service run on the seismic network that was deployed earlier in the year. The project, “Active fault kinematics during non-volcanic rifting in East Africa”, is in collaboration with Beach Petroleum (Tanzania) Ltd., the… Read More G&G pgr students complete seismic service run at Lake Tanganyika, Tanzania
A new paper, titled “Deriving shallow-water sediment properties using post-stack acoustic impedance inversion”, has recently been published in the peer-reviewed journal Near Surface Geophysics by Geology and Geophysics Research Fellow, Dr Mark E. Vardy. In the paper, Mark demonstrates a method whereby key physical properties of the sediments that comprise shallow subsurface can be derived… Read More Deriving shallow water sediment properties from seismic reflection data
A new paper has been published in Geophysical Research Letters, with contribution from current G&G postgraduate research student Thomas Hall, investigating Segmentation of the Sumatran fault. In this paper the authors use a clustering algorithm to partition seismicity into discrete clusters. From a seismology point of view cluster are representatives of source zones and depending on the spatial… Read More New paper on “Segmentation of the Sumatran fault” in GRL
Tim Minshull from G&G has just been awarded a grant to analyse seismic data from the Porcupine Basin west of Ireland, a region where the continental crust has been highly extended but not quite enough to form an ocean basin. Â The project is in collaboration with the Dublin Institute of Advanced Studies (DIAS), the University… Read More Understanding the Porcupine Basin west of Ireland
