2. Questions 1.What are the patterns and surprises in sensor data, and what do they tell us about how external drivers influence lake physical, chemical, and biological processes? 2.How do large gradients in geology, hydrology, and climate influence lake responses to external drivers? 3.What are the essential emergent characteristics from lakes that allow us to generalize processes from a few, highly instrumented lakes to regional and global scales?

10. Technology will… 1. access large repositories of data, and move data seamlessly through a web of models and repositories; 2.accomplish a complex series of tasks in dependable ways; 3.support the interconnection of models, some of which are extremely compute intensive, in flexible and fast ways; 4.provide on-demand access to GLEON scientists from around the world. This functionality extends existing GLEON technology by leveraging proven workflow and distributed technologies available through Condor and data access, visualization and transport technologies through NCHC.
