High-resolution upper crustal structure from OBH data at the TAG Hydrothermal Field, 26°N on the Mid-Atlantic Ridge

Autor: Szu-Ying Lai, Gaye Bayrakci, Bramley Murton, Tim Minshull

The Trans-Atlantic Geotraverse (TAG) segment at 26°N on the Mid Atlantic Ridge (MAR) is notable for hosting hydrothermal mounds and seafloor massive sulphide deposits. At the slow-spreading MAR, detachment faulting plays an important role in control

Insights into exhumation and mantle hydration processes at the Deep Galicia margin from a 3D high-resolution seismic velocity model

Autor: Bhargav Boddupalli, Tim A. Minshull, Gaye Bayrakci, Gaёl Lymer, Dirk Klaeschen, Tim J. Reston

High-resolution velocity models developed using full-waveform inversion (FWI) can image fine details of the nature and structure of the subsurface. Using a 3D FWI velocity model of hyper-thinned crust at the Deep Galicia Margin (DGM) west of Iberia,

International Journal of Greenhouse Gas Control

We present porosity and free gas estimates and their uncertainties at an active methane venting site in the UK sector of the North Sea. We performed a multi-disciplinary experiment at the Scanner Pockmark area in about 150 m water depth to investigat

The offshore Bangladesh includes the northern Bengal fan, where sediment supply from the Ganges and Brahmaputra rivers has resulted in the accumulation of up to 20 km of shallow-marine, fluvio-deltaic and slope sediments that have accumulated during
