Marine CSEM and seismic joint-interpretation for the characterization of methane hydrates and free gas deposits at deep-sea pockmarks

Gas hydrates are currently positioned in the centre of a ‘triple-junction interest’ from both the industry and academic point of view, due to their potential as an unconventional energy resource, geohazard to marine infrastructures and possible role in climate change. The aim of this study is to detect, quantify and characterize the distribution of methane… Read More Marine CSEM and seismic joint-interpretation for the characterization of methane hydrates and free gas deposits at deep-sea pockmarks

Strong presence by G&G Group at the American Geophysical Union (AGU) fall meeting

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

G&G pgr students complete seismic service run at Lake Tanganyika, Tanzania

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

G&G team studying turbulence and sediment dynamics are first to use the Fast Flow Facility at HR Wallingford

Members of the G&G group (coastal processes research theme) have recently had the privilege to be the first external users of the new HR Wallingford Fast Flow Facility (FFF). The FFF is a unique facility that allows studying wave-current-sediment interactions at a large scale. This collaboration came to support the work undertaken by postgraduate researcher Hachem… Read More G&G team studying turbulence and sediment dynamics are first to use the Fast Flow Facility at HR Wallingford

Experimental observation of water saturation effects on shear wave splitting in synthetic rock with fractures aligned at oblique angles

A new paper with experimental observation of water saturation effects on shear wave splitting in synthetic rock with fractures aligned at oblique angles has recently been published, by G&G member Kelvin Amalokwu and colleagues, in Geophysical Journal International. Abstract Fractured rocks are known to exhibit seismic anisotropy and shear wave splitting (SWS). SWS is commonly… Read More Experimental observation of water saturation effects on shear wave splitting in synthetic rock with fractures aligned at oblique angles

Deriving shallow water sediment properties from seismic reflection data

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

Sea surface temperature trends in the coastal ocean

Recent research into coastal sea surface temperature (SST) trends undertaken by Professor Carl Amos have revealed trends that are up to 10 times greater than the global average reported by the IPCC (2013). Research has been carried out in the northern Arabian Gulf (Kuwait), in the northern Adriatic (Venice lagoon), and off the British Columbian… Read More Sea surface temperature trends in the coastal ocean

Mega-scours in Bangladesh

Researchers from the Geology and Geophysics group are currently conducting fieldwork on some of the world’s largest river systems in Bangladesh. Working from river cruise boat, Jon Bull, Mark Vardy, and John Davis are using high-resolution multi-beam bathymetry and boomer seismic reflection techniques to map the surface morphology and subsurface architecture of large scours (so-called… Read More Mega-scours in Bangladesh

Research cruise investigates large submarine landslides around the Nordic Seas

During July 2014 members of the Geology and Geophysics group took part in a major National Oceanography Centre research cruise on board the RV Pelagia. The focus of the cruise, led by Dr Pete Talling, was to investigate the tsunami risk to the coastal areas of the Nordic Sea. The PhD students involved on this… Read More Research cruise investigates large submarine landslides around the Nordic Seas
