EP41F:
The Architecture and Workings of Earth's Critical Zone 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#: 18021

Session Description:
The layers of earth materials and organisms at the Earth’s surface behave as a distinct entity- the critical zone, and fundamentally differ from rock below and atmosphere above.  Although thin on a planetary scale, the critical zone is substantive for the living systems it supports, and significant in modulating the flows of water and sediment to rivers and the sea.   Dynamic interfaces at the top of the vegetation canopy, the ground surface, and at the deep transition to unweathered materials vary spatially, and co-evolve, forming the template on which hydrologic and ecologic processes occur.  Presentations in this session will highlight advances in 1) exploration of the architecture of critical zone and the processes that shape its structure, 2) interactions between organisms and the substrates they live on, and 3) analysis of spatial and temporal variations in water, energy, and biotic activity in the critical zone.
