PP21D:
Evolution of the Earth System I

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17491

Session Description:
Earth has evolved as a coupled system, with rich interactions between biology, geology,

chemistry and climate. A wide array of geochemical and climatic states have existed through a continuously

habitable period of at least 4 billion years. Understanding this evolution is necessarily an interdisciplinary problem.

We welcome contributions which chart or explain this evolution, with either observational or theoretical

approaches, for any period in Earth history. Topics will include evolution of major geochemical cycles (C, O, N),

major climatic events and the co-evolution of life and the environment.
