SUMMARY:The Co-Evolution of the Geosphere and Biosphere: A “Big-Data”

DESCRIPTION:\nA fundamental goal of the geological sciences is the deep un
 derstanding of planetary evolution. Recent research employing large and gr
 owing data resources in mineralogy\, petrology\, paleobiology\, paleotecto
 nics\, geochemistry\, and proteomics underscores the intertwined influence
 s of life and rocks on Earth’s evolution. We therefore are exploring “
 big-data” approaches to longstanding problems in geology.\nData-driven d
 iscovery depends on three key developments: (1) enhanced data resources in
  diverse geo- and bio-related fields\; (2) development and implementation 
 of powerful analytical and visualization methods\; and (3) creative framin
 g of questions related to the evolving geosphere and biosphere in space an
 d time.  \n\nWe are especially interested in visualization methods that il
 lustrate multiple attributes of complex systems. In particular\, network a
 nalysis provides a dynamic\, quantitative\, and predictive visualization f
 ramework for employing “big data” to explore complex and otherwise hid
 den higher-dimensional patterns of diversity and distribution in mineralog
 y\, paleobiology\, and protein structures. Network analysis  facilitates q
 uantitative comparison of coexistence patterns simultaneously among hundre
 ds of mineral or fossil species and their localities\, exploration of vari
 ed paragenetic modes of mineral groups\, investigation of changing pattern
 s of mineral and fossil occurrence through deep time\, and comparisons of 
 lithologies from different planets and moons. Network analysis\, furthermo
 re\, represents an effective visual approach to teaching and learning in E
 arth and planetary sciences.\n
