Without ever opening their textbooks, my high school biology students can usually give a plausible-sounding account of biogeochemical
Riaz has been selected to spend eight weeks at the Department of Aquatic Ecology and Environmental Biology, Institute of Water and Wetland Research (IWWR), Radboud University, the Netherlands, where he will learn techniques for using stable isotopes in the biogeochemical
cycling of nutrients, especially nitrogen and carbon.
Younger sediments are enriched with organic matter and, under certain biogeochemical
conditions, arsenic from soil gets released into the groundwater," explained Shah, who has published his findings in the scientific journal Current Science.
In a paper published in Global Biogeochemical
Cycles, (1) Dr Canadell and his co-authors concluded from modelling studies that frozen high-latitude soils contain vast quantities of carbon, about twice as much carbon as is currently in the atmosphere, and that destabilisation of this frozen 'carbon pool' could influence carbon-climate feedbacks.
Research topics include local, regional and global water pollution, exposure and health problems, health risk analysis of water pollution, methods of quantification and analysis of risk under uncertainty, aquatic biogeochemical
processes in antural and engineered systems and health effects, analysis of pollution, exposure and health data.
He lists his main research interests as stratospheric and tropospheric chemistry, and their role in the biogeochemical
cycles and climate.
Ron teaches graduate courses in Chemical Oceanography, Sediment Biogeochemistry, Ocean Variability and Global Change, Marine Microbial Ecology, Marine Biogeochemical
Processes and Seminar in Marine Science.
All sides in the limits-to-growth debate would probably agree on the following two observations: First, the dynamic, interactive system of complex biogeochemical
cycles that constitutes Earth's surface environment is falling increasingly under the influence of a single dominant life form: us.
provided $950,000 to support a research cruise led by WHOI geophysicist Maurice Tivey in July that will use the WHOI-operated underwater vehicles Jason and ABE to explore the biogeochemical
phenomena that created gold-rich seafloor deposits 30 miles off Papua New Guinea, to which the company has mining rights.
Characterizing the biogeochemical
processes influencing climate is a major objective of Earth system science.
Marine viruses and their biogeochemical
and ecological effects.
The HgSe interaction is apparent throughout the Hg cycle, influencing its transport, biogeochemical
exposure, bioavailability, toxicological consequences, and remediation.
