Atmospheric Exchange with Marine and Terrestrial Ecosystems

Session ID#: 159254

Session Description:
The atmospheric flux of nutrients and pollutants to and from ecosystems links land, atmosphere, and ocean processes within the Earth system. Interactions between elements and ecosystems modulate carbon and nitrogen cycles and changing fluxes have significant impacts on global biogeochemistry, climate, and society across spatiotemporal scales. Biogeochemical cycles are undergoing rapid change due to anthropogenic activity, requiring an interdisciplinary approach to understanding connections between element cycles, climate, and ecosystem health. We encourage submissions detailing measurements from remote sensing, field campaigns, and laboratory experiments, as well as studies which consider past, present, or future modelling perspectives. Topics of particular interest are, but not limited to:

  1. Links between atmospheric aerosol deposition, from natural and anthropogenic sources, and ecosystem productivity in nutrient limited areas,
  2. Links between aerosol nutrient inputs to ecosystems and past abrupt pCO2 changes in the atmosphere,
  3. Insights on the biogeochemistry of past land aerosol precursors from continental proxy records,
  4. Projections of how nutrient fluxes may change in a changing climate, and the impacts for biogeochemical cycles, climate, and society
