Mantle motions have major effects on topography and the distribution of ice sheets. The motions are key for researchers trying to properly parse past mantle movement.
Greenland
Finding the Frequency of a Fjord
A massive tsunami churned up a mysterious 9-day noise in East Greenland. As the climate warms, more fjords may start singing.
The 16 September 2023 landslide on the margin of Dickson Fjord in Greenland
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. There has been quite a stir over the last week regarding a remarkable paper (Svennevig et al. 2024) that was published in the journal Science, describing a series of events that occurred […]
Swedish Icebreaker Is the First to Dig Into Greenland’s Remote Victoria Fjord
Data collected aboard Oden will shed light on the dynamics of the Greenland Ice Sheet.
Scientists Find Clues to Atlantic Current’s Future in Ancient Iceberg Debris
Modern ice loss from Greenland rivals the most dramatic episodes of ice sheet collapse.
Greenland Could Have Records of 3.7-billion-year-old Geomagnetic Fields
Scientists argue that paleomagnetic field tests preserve a geomagnetic field record acquired as chemical remnant magnetization in banded iron formations in southwest Greenland.
Beneath the Ice: Greenland’s Geology Revealed in New Map
Advances in remote sensing offered an opportunity to redraw Greenland’s geologic map for the first time in 15 years.
Monitoring Polar Ice Change in the Twilight Zone
Landsat’s new extended data collection program is mapping Arctic and Antarctic regions year-round, even in polar twilight.
How Did We Miss 20% of Greenland’s Ice Loss?
The ice loss was hidden in places existing monitoring methods can’t reach, such as hard-to-map fjords. Machine learning helped scientist revise mass loss estimates and uncover patterns in glacial retreat.
Glaciers Rise and Fall—and Melt—with Tides
The effect of ocean water creeping beneath Greenland ice is stronger than scientists realized.
