An EGU session that may be of interest (abstract deadline Jan 10): Large-scale experiments on ecohydrological and biogeochemical processes of the Critical Zone (co-organized)
SSS12.6/BG1.60/GI4.14/GM5.11/HS11.4 https://meetingorganizer.copernicus.org/EGU2019/session/31518 Convener: Werner Gerwin Co-conveners: Jin Lin , Laura Meredith Abstract submission Hydrological cycles and soil-related biogeochemical processes are the backbone of the Critical Zone and their existence is crucial for central ecosystem functions and services. Most of these basic processes are not directly accessible and several of them become apparent only after disturbance or system modifications when single ecosystem processes produce distinct signals. Thus, experiments are widely used for elucidating Critical Zone processes. Large-scale experiments with whole ecosystems or even parts of them are expensive and time-consuming and, therefore, not that widely spread. Nonetheless, large-scale experiments on Critical Zone behavior have been carried out in the past and also today several exciting experiments using sophisticated infrastructures and monitoring techniques are in use at different sites worldwide. Well-known flagship sites in this sense are, e.g., Biosphere2 in the USA or Hydrohill in China. In addition, post-mining landscapes worldwide offer multiple opportunities for establishing artificial experimental sites for various purposes. Many experimental sites are based on hydrological catchments as integrative landscape units. Other large-scale experiments focus on selected parts of ecosystems which were modified or transplanted. Against this background this session tries to create a global overview on large-scale landscape experiments on ecohydrological, pedological, biogeochemical or ecological processes within the Critical Zone. Insights into flagship sites of Critical Zone research are envisaged as well as papers presenting other kinds of landscape observatories in natural or constructed environments. We invite interdisciplinary contributions dealing with (1) exemplary concepts of large-scale experimental sites and landscape observatories in Critical Zone research, (2) concepts for monitoring Critical Zone processes in experimental landscape observatories, (3) results of experiments and monitoring studies, as well as (4) modelling approaches for explaining process behavior.
