  4. Greenland • Changes in the Velocity Structure of the Greenland Ice Sheet • Eric Rignot and Pannir Kanagaratnam • Science 17 February 2006: Vol. 311. no. 5763, pp. 986 – 990

  5. Jacobshavn • Greenland’s mass loss doubled in the last decade: • The Greenland ice sheet contains enough water to cause a global sea level rise of seven meters. Since 2000, the ice sheet has lost about 1500 Gt in total (1 Gt is the mass of 1 cubic kilometre of water) representing on average a global sea level rise of about half a millimeter per year, or 5 mm since 2000. Jakobshavns Discharge: 24 km3 / yr (5.6 mile3 / yr) in 1996 46 km3 / yr (10.8 mile3 / yr)in 2005

  6. Support CReSIS with Cyberinfrastructure • Base and Field Camps for Arctic and Antarctic expeditions • Training and education resources at ECSU • Collaboration Technology at ECSU • Lower-48 System at Indiana University and ECSU to support off line data analysis and large scale simulations (next stage) • Full system to be installed in next month (total ~ 20 TF)

  7. PolarGrid Greenland 2008 Base System (Ilulissat Airborne Radar) 8U, 64 core cluster, 48TB external fibre-channel array Laptops (one off processing and image manipulation) 2TB MyBook tertiary storage Total data acquisition 12TB (plus 2 back up copies) Satellite transceiver available if needed, but used wired network at airport used for sending data back to IU Base System (NEEM Surface Radar, Remote Deployment) 2U, 8 core system utilizing internal hard drives hot swap for data back up 4.5TB total data acquisition (plus 2 backup copies) Satellite transceiver used for sending data back to IU Laptops (one off processing and image manipulation)

  8. PolarGrid Antarctic 2008/2009 Base System (Thwaites Glacier Surface Radar) • 2U, 8 core system utilizing internal hard drives hot swap for data back up • 11TB total data acquisition (plus 2 backup copies) • Satellite transceiver used for sending data back to IU • Laptops (one-off processing and image manipulation) IU-funded Sys-Admin • 1 admin Greenland NEEM 2008 • 1 admin Greenland 2009 (March 2009) • 1 admin Antarctica 2009/2010 (Nov 09 – Feb 2010) • Note that IU effort is a collaboration between research group and University Information Technology support groups

  9. PolarGrid goes to Greenland

  10. NEEM 2008 Base Station

  11. Field Results – 2008/09 “Without on-site processing enabled by POLARGRID, we would not have identified aircraft inverter-generated RFI. This capability allowed us to replace these “noisy” components with better quality inverters, incorporating CReSIS-developed shielding, to solve the problem mid-way through the field experiment.” Jakobshavn 2008 NEEM 2008 GAMBIT 2008/09

  12. ECSU and PolarGrid Assistant Professor, Eric Akers, and graduate student, Je’aime Powell, from ECSU travel to Greenland Initially A base camp 64-core cluster, allowing near real-time analysis of radar data by the polar field teams. An educational videoconferencing Grid to support educational activities PolarGrid Laboratory for students ECSU supports PolarGrid Cyberinfrastructure in the field

  13. PolarGrid Lab Mac OS X Public IP accessible through ECSU firewall Ubuntu Linux Windows XP Additional Software Desktop Publishing Ubuntu Linux Word Processing Web Design Programming Mathematical Applications Geographic Information Systems (GIS)

  14. Data Deluge in Earth Science • Common Themes of Data Sources • Focus on geospatial, environmental data sets • Data from computation and observation. • Rapidly increasing data sizes • Data and data processing pipelines are inseparable.

  15. The Earth, its resources and inhabitants face challenges related to changing climate and natural disasters How does our changing climate influence the oceans and ice sheets and how are they interacting? Climate Change Guided by: Intergovernmental Panel on Climate Change Ocean temperature atmospheric exchange Changing sea ice Rising sea level How do the tectonic plates and fault systems interact to produce earthquakes? Natural Disasters Provide disaster information and understand potential for future events Guided by: OSTP CENR Subcommittee for Disaster Reduction Earthquakes Earthquakes Volcanoes

  16. Enabling Repurposing of Data: Applications to Civil Infrastructure and Crisis Management Provide access to clean water Restore and improve urban infrastructure Develop carbon sequestration methods Civil Infrastructure Guided by: Grand Challenges for Engineering Water pipe breaks Provide disaster information and understand potential for future events Crisis Management Guided by: OSTP CENR Subcommittee for Disaster Reduction

  17. Natural Disasters Earthquakes Tectonics, Plate Movement Tsunamis Broken Water Pipes (?) Indicators of Changing Earth

  18. Crisis Management Fires Floods Potential for future occurrences
