Ocean and Earth Science, National Oceanography Centre Southampton

Research Group: Geochemistry

Geochemistry comprises more than 30 researchers and postgraduate students who apply state-of-the-art geochemical analysis and modelling to scientific questions of major societal, economic and environmental importance.

Currently Active: Yes

Group Overview

Our diverse research activicty can be broadly divided into 8 themes. Click the theme title for more information.

Past Present and Future Environmental Change

  • We aim to achieve a better understanding of the major geochemical cycles of the Earth System and the impact of humanities action upon them. Our work also focuses on the reconstruction of the climate of the past to better understand the drivers of natural climate and environmental change.

Environmental Geochemistry and Radioactivity

  • Research into how we interact with our environment and its impact on us
  • Encompasses specialist radioanalytical research and specialist services offered by our Industrial Advisory Unit, GAU-Radioanalytical

Volcanic Processes

Hydrothermal Processes and Mineral Deposits

  • Hydrothermal processes represent one of the major mechanisms for chemical and heat transfer on Earth. They have a profound influence on ocean chemistry and they play host to unique ecosystems. In addition many of the world's most important resources are sourced from deposits that formed as a result of hydrothermal activity.

Formation and Evolution of the Ocean Crust

Medical Geochemistry

Geochemical Ecology

Carbon Storage and Geoengineering

Our strengths include:

  • ultra-low level trace element analyses
  • radiogenic isotope geochemistry and geochronology
  • fluid and volatile analysis
  • environmental radiochemistry
  • geochemical ecology and biominerals
  • speciation and reaction modelling
  • analytical technique development and refinement
