Global Biogeochemical Cycles
The earth system involves interactions amongst the physical climate, chemical cycles and living organisms. Faculty and staff in the global biogeochemical cycles focus area work on characterizing these interactions, developing numerical models of them, and using these models to evaluate how changes in one part of the system affect other parts.
Examples of the questions studied include:
- How much carbon dioxide is taken up by terrestial ecosystems and the ocean?
- Why is atmospheric carbon dioxide lower during glacial periods?
- How will climate change affect fisheries?
- How do changes in the biosphere directly affect the physical climate?
- How do the nitrogen, carbon, and silicon cycles interact?
