Geoscience Enterprise Architecture for Research (GEAR) is an EarthCube conceptual design project focused on developing the foundations of a community-driven cyberinfrastructure (CI) to address the grand challenges of integrative Earth science research and education. We are approaching EarthCube design as a complex and evolving socio-technical federation of systems, in which communication between various domain subsystems, people and organizations enables more comprehensive, data-intensive research designs and knowledge sharing. The poster presents the status and key findings of the project, describe our design methodology and challenges, and discuss main project deliverables. We specifically focus on cyberinfrastructure patterns enabling scientifically sound discovery and reuse of information resources and expertise across geoscience domains, reproducible collaborative science, and efficient scholarly communication, engagement and interaction between geoscientists and computer scientists.
