Mantle Motion Matters for Mapping Modern (and Ancient) Ice

by Alka Tripathy-Lang 11 December 202411 December 2024

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.

Finding the Frequency of a Fjord

by J. Besl 9 October 202415 October 2024

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

by Dave Petley 18 September 202418 September 2024

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 […]

Greenland Could Have Records of 3.7-billion-year-old Geomagnetic Fields

by Agnes Kontny 7 May 20246 May 2024

Scientists argue that paleomagnetic field tests preserve a geomagnetic field record acquired as chemical remnant magnetization in banded iron formations in southwest Greenland.

How Did We Miss 20% of Greenland’s Ice Loss?

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 8 February 20242 July 2024

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.
