Research Group: Geology and Geophysics

Currently Active: 
Yes

The Geology and Geophysics Research Group includes about 60 staff and PhD students. We are among the most active research groups in this field in Europe.

Our specific research strengths include:

  • the tectonics and dynamics of active plate boundaries and continental margins including sub-seabed fluid flow processes
  • continental slope and deep-water sedimentation processes including mass-wasting, geohazards, environmental geology and ecosystems
  • the role of fault system growth and evolution in crustal deformation
  • coastal and continental shelf sedimentary environments and processes including the interaction with engineering structures
  • high resolution quantitative and qualitative analysis of the seabed and immediate sub-surface using active and passive acoustics and controlled source electromagnetics

Our work is underpinned by world-class facilities for controlled source electromagnetic sounding, ocean bottom seismology, high resolution sea floor imagery, and the analysis of cores and other sea-bottom samples.

Associated research themes

Coastal and Shelf Processes

High Resolution Marine Geophysics

We have over 20 years experience of collecting high resolution geophysical data for research projects as diverse as small object detection (including forensic work); wreck based surveys, Quaternary natural and archaeological landscape studies, neotectonics, and large scale sedimentological and structural analysis.

3D Chirp

3d Chirp is a surface-towed sub-bottom profiling system capable of imaging the upper tens of metres of the sub-surface on three dimensions with decimetric horizontal and centimetric vertical resolution.

Coastal Laboratories

The geology and geophysics research group operates three labs focusing on the study of coastal and shelf sea hydrodynamics and sediment dynamics. Our Coastal Processes and the Coastal Dynamics labs host a range of straight, recirculating and annular flumes equipped with a variety of high-frequency instruments and sensors, and are used for teaching and research into boundary layers, sediment transport and scour, submarine gravity flows and flow/sediment interactions with biota. The Sediment Analysis Lab is equipped with a range of tools used to analyse cohesive and non-cohesive sediment samples, including particle size distribution, grain texture and composition, and bulk sample properties; including a settling column and a Laser Sizer.

OBIC

The Ocean Bottom Instrumentation Consortium aims to provide the academic and commercial communities with access to multi-sensor, versatile seabed instruments to enable sub-surface geophysical imaging at high vertical and lateral resolution.

Seafloor EM

The university is equipped to carry out field research programmes in CSEM surveys - for both academic and applied research topics.

Geosciences Advisory Unit (GAU)

GAU-Radioanalytical is an industry and government-agency focussed organisation that offers specialist radioanalytical research and analytical services.

Rock Preparation and Thin-Sectioning Laboratory

This facility primarily focuses on making high quality sections of a range of materials for teaching and research. Cutting services, vacuum impregnation and staining techniques are also available.

Research Vessels

We have two vessels based at NOCS that are available to staff and students of Ocean and Earth Science. R.V. Callista and R.V. Bill Conway.

Palaeomagnetism and Environmental Magnetism Laboratory

This facility houses state-of-the-art instrumentation as well as a shielded room to support paleomagnetism, rock and mineral magnetism, magnet stratigraphy, and palaeoenvironment related research.

X-Ray Diffraction Facility

The XRD facility located at NOCS provides a service for the qualitative or quantitative analysis of rock samples to determine bulk mineralogy and/or clay mineralogy
