A new web-based data portal gives scientists access to more than 40 years of satellite imagery, providing seasonal to long-term insights into outflows from Greenland's ice sheet.

Major Ocean Circulation Pattern at Risk from Greenland Ice Melt
The current warming trend could mean the collapse of ocean's global conveyor belt, which would have far-reaching effects on climate around the world. But this collapse could still be avoided.
Scientists Spend Arctic Winter Adrift on Sea Ice
A hovercraft-based ice drift station gives researchers access to previously inaccessible regions of the changing Arctic sea ice cover off the coast of Greenland.
Climate-Driven Change in Ice-Free Areas of Greenland
KAIRN (Kangerlussuaq International Research Network) 2nd Annual Meeting; Acadia National Park, Maine, 4–7 May 2016
A River Network Preserved Beneath the Greenland Ice Sheet
An ancient drainage basin covering one fifth of Greenland predates the ice sheet and strongly influences the modern Jakobshavn Glacier, according to a new analysis of ice-penetrating radar data.
Evidence of an Extinct Ocean Basin Detected Beneath Greenland
An analysis of a seismic and gravity anomaly discovered in the middle mantle sheds new light on ancient oceans, the mantle's evolution, and ancient magmatism in the Arctic.
Giant Balls of Bacteria Pile Up on Arctic Lake Beds, Ooze Toxin
Researchers have found cyanobacteria colonies as big as softballs thriving unexpectedly on shallow Greenland lake bottoms, exuding liver-damaging microcystin. Locals dubbed them "sea tomatoes."
Sea Level Rise Due to Warming, Weakening of Greenland Glaciers
Increasing ice temperatures and decreasing ice viscosities could lead to "thermal-viscous collapse" of the Greenland ice sheet, raising sea levels as much as 51 centimeters over the next 500 years.
Near-Surface Aquifer Discovered on Svalbard Glacier
Arctic glacier aquifer may respond more rapidly to climate change than larger aquifers found on the Greenland ice sheet.
What Darkens the Greenland Ice Sheet?
Limited observational data sets and incomplete surface energy balance models constrain understanding of the driving processes for Greenland's ice sheet.
