The 1979-2005 Greenland ice sheet melt extent from passive microwave data using an improved version of the melt retrieval XPGR algorithm [PDF]

, 2007
Analysis of passive microwave satellite observations over the Greenland ice sheet reveals a significant increase in surface melt over the period 1979-2005. Since 1979, the total melt area was found to have increased +1.22 x 10ˆ7 kmˆ2.

Relative Sea-Level Changes and Ice Sheet History in Finderup Land, North Greenland

Frontiers in Earth Science, 2018
Rising global sea level caused by melting ice sheets poses a major challenge in a persistently warming climate. The Greenland Ice Sheet (GrIS) is among the main contributors, and in order to make accurate predictions of future ice retreat and sea level ...

Impact of model physics on estimating the surface mass balance of the Greenland ice sheet [PDF]

, 2007
Long-term predictions of sea level rise from increased Greenland ice sheet melting have been derived using Positive Degree Day models only. It is, however, unknown precisely what uncertainties are associated with applying this simple surface melt ...

Sliding dominates slow-flowing margin regions, Greenland Ice Sheet

Science Advances, 2019
We measure sliding-dominated plug flow over a hard bed during winter and show that this flow style is typical of margins in Greenland. On the Greenland Ice Sheet (GrIS), ice flow due to deformation and sliding across the bed delivers ice to lower ...

Radiostratigraphy Reflects the Present-Day, Internal Ice Flow Field in the Ablation Zone of Western Greenland

Frontiers in Earth Science, 2018
Englacial radar reflectors in the ablation zone of the Greenland Ice Sheet are derived from layering deposited in the accumulation zone over past millennia. The original layer structure is distorted by ice flow toward the margin.

Cascading lake drainage on the Greenland Ice Sheet triggered by tensile shock and fracture

Nature Communications, 2018
Supraglacial lakes on the Greenland Ice Sheet are expanding inland, but the impact on ice flow is equivocal because interior surface conditions may preclude the transfer of surface water to the bed.

Decreasing cloud cover drives the recent mass loss on the Greenland Ice Sheet

Science Advances, 2017
Reduction in summer cloud cover over the Greenland Ice Sheet is the main driver of recent melt. The Greenland Ice Sheet (GrIS) has been losing mass at an accelerating rate since the mid-1990s.
