National Oceanography Centre, Southampton: Geochemistry - Research is focused on two main themes, quantifying geochemical exchanges between Earth reservoirs and quantifying, forecasting, and mitigating the effects of climate change, pollution, global consumption and geohazards on society. Petroleum and Environmental Geochemistry Group - At the School of Geography, Earth and Environmental Sciences, University of Plymouth, UK. Includes details of the Group, the research being undertaken and publications. Geochemistry Research Group: University of Bristol - Research into understand natural processes on a range of temporal and spatial scales, specialising in the use of isotopic tracers to understand the nature and chronology of cycling between the major reservoirs of the Earth. Environmental Geochemistry Group - At the Johannes Gutenberg-University in Mainz, Germany. Undertaking basic and applied research into speciation and transformation of trace metals and metalloids during biogeochemical processes in both natural and anthropogenic environments. Woods Hole Oceanographic Institution Marine Chemistry and Geochemistry - Devoted to the study of chemical processes in the ocean and chemical fluxes to and from the oceans. Staff lists, facilities, talk schedules, and research summaries. 7*M Research Group at Arizona State University - This diverse research group's interests center on meteorites, mercury geochemistry, microprobe analysis, mineralogy and other associated fields. Includes details of current projects, publications, facilities and personnel. Organic Geochemistry Unit - At the School of Chemistry, Bristol University, UK. Research is focused on understanding the biogeochemistry of modern-day and ancient environments and the way that it is affected by natural processes and the actions of mankind. Division of Geochemistry: Lamont-Doherty Earth Observatory - Researchers seek to understand Earth’s environments by studying its history and the processes that have governed these environments, using chemical and isotope analyses of samples of air, water, biological remains, rocks and meteorites Environmenal Geochemistry Research - At the Byrd Polar Research Center, Ohio State University, USA. Includes details of the people and the varied research projects in which they are involved.
