Fine-scale gas distribution in marine sediments assessed from deep-towed seismic data

Stephan Ker from Ifremer (the French national institute for marine research) and co-authors including  Graham Westbrook and Tim Minshull from G&G have published a paper in Geophysical Journal International that uses novel deep-towed seismic data and a novel technique to infer the detailed properties of gas pockets in marine sediments.  The seismic data were collected… Read More Fine-scale gas distribution in marine sediments assessed from deep-towed seismic data

Deep-water continental margins: Geological and economic frontiers

Tiago Alves from Cardiff University, with three co-convenors including Tim Minshull from G&G, have published an introductory paper in the recent special volume of Basin Research that includes some of the work originally presented at a Geological Society conference in October 2012.  The paper summarises the contents of the volume, which cover the measurement of… Read More Deep-water continental margins: Geological and economic frontiers

Sediment storage and reworking on the shelf and in the Canyon of the Indus River-Fan System since the last glacial maximum

We might hope that the deep-water sedimentary record reflects processes on land in the region where the sediments are sourced, giving us insight into a combination of tectonic activity and climatic changes. A study looking at the Indus Shelf and Canyon offshore Pakistan led by Peter Clift and including Tim Henstock from G&G suggests this isn’t the case, even… Read More Sediment storage and reworking on the shelf and in the Canyon of the Indus River-Fan System since the last glacial maximum

Thermal models of dyke intrusion during development of continent–ocean transition

Kat Daniels from Cambridge University along with a team of scientists including Derek Keir from G&G, published a paper in EPSL highlighting the influence of dyke intrusion on heating the surrounding crust in extensional tectonic settings. They used numerical modelling to show that if intrusions repeatedly focus at the same location for just a few million… Read More Thermal models of dyke intrusion during development of continent–ocean transition

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

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

G&G Staff awarded Royal Astronomical Society Bullerwell Award for Second Year in a Row

The Royal Astronomical Society has recently announced that Dr. Kate Rychert will be the 2014 recipient of the Bullerwell award, which is given annually to “An outstanding young British Geophysicist”. As part of this award Kate will be giving an honorary lecture at EGU and the BGA research in progress meeting, both in 2014. This… Read More G&G Staff awarded Royal Astronomical Society Bullerwell Award for Second Year in a Row

The influence of coastal reefs on spatial variability in seasonal sand fluxes

A new paper led by G&G Research Fellow, Shari Gallop, has just been published in Marine Geology. The focus of the paper was on how the topography of coastal reefs drives alongshore variation in the mode and magnitude of erosion and accretion on a sandy beach in southwestern Australia. To achieve this, sub aerial beach surveys were… Read More The influence of coastal reefs on spatial variability in seasonal sand fluxes
