Ocean and Earth Science, National Oceanography Centre Southampton

Research Group: Geology and Geophysics

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.

Currently Active: Yes

Group Overview

Our specific research strengths include:

  • the tectonics and dynamics of active plate boundaries and continental margins including subseabed fluid flow processes
  • deep-water sedimentation processes including mass-wasting, geohazards, environmental geology and ecosystems
  • the role of fault system growth and evolution in crustal deformation
  • high resolution geophysics, including geophysical marine archaeology and sediment acoustics.

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

Geosciences Advisory Unit (GAU)

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

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.

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.

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.

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.
