Centennial Session: Biogeosciences at the threshold: What our living planet has taught us so far
Session ID#: 83438
Session Description:
Biogeosciences has come to represent a broad research community’s attempts to understand the linkages and feedbacks between the physical, chemical, and biological processes on Earth and beyond. It has matured into a robust field of research, exploiting the tools of Geochemistry, Biogeophysics, Ecology (Terrestrial, Marine, Microbial), Molecular Biology and Astrobiology. Transformative research has led to key insights regarding ecosystem function, the origins of life, the interactions between the biosphere, lithosphere, hydrosphere and atmosphere, and perhaps most critically, the role of modern society in the earth system. This session focuses on the state of the art in concepts, observation, experimentation, modeling, and emerging means that provide the foundation to explore processes and interactions over the next century.
