Climate change biogeochemical cycles
Current Projects
A principal research activity is the cycle of carbon dioxide. The current atmospheric CO2 increase is only half the carbon emission from fossil fuel combustion. Where is the missing carbon? We use details of the atmospheric CO2 distribution (e.g. the difference in hemispheric loading, the changes in the seasonal amplitude over time) together with atmospheric transport models to deduce the location of the carbon sink. We hypothesized that the terrestrial biosphere of the northern hemisphere may be as important as the oceans as a repository for anthropogenic CO2. By combining satellite observations of the biosphere, observations of the year-to-year variations in the atmosphere and biosphere, and in-situ process studies, we identify the sensitive ecosystems and the processes responsible for the carbon sequestration.
Another research focus is the dust cycle. Fine dust particles lofted from arid surfaces are transported long distances. While airborne, they reflect sunlight, but may, depending on their sizes and composition, absorb terrestrial radiation. When deposited to the surface oceans, the iron in the dust may be the critical limiting micronutrient for marine productivity in some ocean regions. To tackle this problem, we are combining mineralogic information about soil particles, satellite and in-situ observations, atmospheric circulation models and ocean biology models to gain an appreciation of the many roles of dust. Our finding that about half the atmospheric dust loading may be from recent disturbances (e.g. cultivation, Sahel-Sahara boundary shifts) leads to new questions about how land clearing may have consequences on marine productivity and the abundance of carbon dioxide in the atmosphere.
