 Joellen L. Russell
Assistant Professor, Biogeochemical Dynamics
Biogeochemical dynamics refers to interactions between the biological, geological and chemical components of the Earth's environment.
These dynamics are influenced by interactions between organisms and their surroundings, including water, air, soil and sediments. In the
Biogeochemical Dynamics Laboratory (BGDL), we use (and when possible, collect) in situ and satellite measurements of the ocean, the atmosphere,
terrestrial vegetation and ocean bottom sediments. We interpret these data using statistical analyses, ocean general circulation models
and coupled climate models.

Research
Current BGDL research focuses on the impact of global climate changes on interannual variability in the carbon cycle.
Changes in the physical climate system affect fluxes between reservoirs of carbon.
One example is the changes in the Westerly Winds, which have moved
poleward and increased over the last 30 years in both hemispheres, possibly as the first and most ferocious of the impacts of global warming.
In the ocean, the shift of the Westerly Winds over the Southern Ocean around Antarctica is changing the creation and destruction of the water masses
critical to the global ocean uptake of carbon dioxide and heat.
On land, the primary impact of this shift in the Northern Hemisphere Westerly Winds on atmospheric carbon dioxide is expressed through changes in
Northern Hemisphere terrestrial vegetation.
