The Critical Zone is the thin Earth layer between the top of thre tree canopy down to the unweathered rocks (Giardino, 2016).
SUMMITS is an umbrella website for past and present projects on the biogeochemistry of this essential Earth’s layer in specific geographic areas mostly high altitude and high latitude areas. We are calling the Frontier Critical Zones because they are abruptly facing Global Changes.
SUMMITS clusters specific project webpages as well redirects to friend projects and pages.
