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

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.

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

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.
