Jacobshavn


Jakobshavns Discharge:
24 km3 / yr (5.6 mile3 / yr) in 1996
46 km3 / yr (10.8 mile3 / yr)in 2005
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.

NEEM 2008
“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.”

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
How does our changing climate influence the oceans and
ice sheets and how are they interacting?
