The dynamics of submarine gravity currents

Esther Sumner has two new papers on the dynamics of field-scale submarine gravity currents in the Black Sea. Both studies made use of NERCs state-of-the-art autonomous underwater vehicle Autosub3 to measure the dynamics of the flow. A paper published in Geophysical Research Letters presents the first direct measurements of hydraulic jumps in an active submarine… Read More The dynamics of submarine gravity currents

Seismic imaging of lithospheric structure and the onset of melting beneath Galapagos

Kate Rychert and Nick Harmon have a new paper published in Earth and Planetary Science Letters about seismic imaging of crust and mantle discontinuity structure beneath the Galapagos Archipelago. They image a lithosphere-asthenosphere boundary that is too thick to be consistent with a thermally defined plate, indicating a compositional component. They also image discontinuities related… Read More Seismic imaging of lithospheric structure and the onset of melting beneath Galapagos

GSNOCS part of NERC funded Centre for Doctoral Training in Oil & Gas Research

Today we can announce the Graduate School of the National Oceanography Centre Southampton’s (GSNOCS) participation in a new, NERC co-funded £8 million Centre for Doctoral Training in geological and environmental research relevant to the oil and gas sector (see the full press announcement). As a consequence we have three funded PhD studentships on offer every… Read More GSNOCS part of NERC funded Centre for Doctoral Training in Oil & Gas Research

7th annual Universities High Voltage Network Colloquium UHVNet 2013

John Emeana and Tim Hughes are two second year PhD students in the Geology and Geophysics group here at the University of Southampton. Both John and Tim’s work is focused on investigating how thermal properties of marine sediments affects the performance of high voltage (HV) cables that are buried under the seafloor. Both work as… Read More 7th annual Universities High Voltage Network Colloquium UHVNet 2013

Magma fluxes at Soufrière Hills Volcano, Montserrat

Catherine Annen from Bristol University,  with Tim Minshull and former PhD student Michele Paulatto from G&G, have published a paper in the Journal of Petrology in which they estimate on different timescales the rate that magma flows into the magma storage region beneath the active Soufriere Hills Volcano.  They use computer models of magma chamber… Read More Magma fluxes at Soufrière Hills Volcano, Montserrat
