With growing technical sophistication in the earth sciences and increasing specialization within its subdisciplines, geoscientists face an organizational problem when we want to tackle grand research challenges that span many disciplines. How do we bring the various fields together to leverage their individual strengths and create something more than the sum of the parts? This is the problem that CIDER (Cooperative Institute for Dynamic Earth Research) attempts to solve...
