EGU2013 - GCII Session BG5.1: Biospheric feedbacks on the Earth system

Event Dates: 7-12 April 2013
Location: Vienna, Austria
Convenors: Andrew Friend, Bethan Jones, Meike Vogt, Sönke Zahele, Han Dolman, Aideen Foley, Mehera Kidston, Gerardo López-Saldaña, Ioannis Bistinas, Catherine Morfopoulos

This session examined the biogeochemical processes that are likely to affect the evolution of the Earth system over the coming decades, with a focus on the dynamics of marine and terrestrial ecosystems and the development of improved understanding through (a) fieldwork and laboratory experiments, (b) development of new observational datasets, both modern and palaeo, and (c) simulations using numerical models. Novel approaches combining observational datasets with models to improve constraints were particularly well represented. This session not only included contributions from all the GREENCYCLESII fellows, but it also included significant contributions from non-network members with an inviated talk from Dr. Yiqi Luo, University of Oklahoma. Further details on the presentations made during the oral and poster sessions can be found below.
