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 Jakobshavns Discharge: 24 km 3 / yr ( 5.6 mile 3 / yr) in km 3 / yr ( 10.8 mile 3 / yr )in 2005

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 2008GAMBIT 2008/09

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.

The Earth, its resources and inhabitants face challenges related to changing climate and natural disasters Climate Change Natural Disasters How does our changing climate influence the oceans and ice sheets and how are they interacting? How do the tectonic plates and fault systems interact to produce earthquakes?
