Accelerating glacier volume loss on Juneau Icefield driven by hypsometry and melt-accelerating feedbacks
Autor: Bethan Davies, Robert McNabb, Jacob Bendle, Jonathan Carrivick, Jeremy Ely, Tom Holt, Bradley Markle, Christopher McNeil, Lindsey Nicholson, Mauri Pelto
Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-19 (2024)
Abstract Globally, glaciers and icefields contribute significantly to sea level rise. Here we show that ice loss from Juneau Icefield, a plateau icefield in Alaska, accelerated after 2005 AD. Rates of area shrinkage were 5 times faster from 2015–20

Evolution of the dynamics of Airdrop Glacier, western Axel Heiberg Island, over a seven-decade-long advance
Autor: Benoît Lauzon, Luke Copland, Wesley Van Wychen, William Kochtitzky, Robert McNabb
Publikováno v: Arctic Science, Vol 10, Iss 1, Pp 48-68 (2024)
Various remotely sensed data, including historical aerial photographs, declassified intelligence satellite photographs, optical satellite imagery, and synthetic aperture radar data, were used to undertake the first comprehensive reconstruction of the

Dynamics throughout a complete surge of Iceberg Glacier on western Axel Heiberg Island, Canadian High Arctic
Autor: Benoît Lauzon, Luke Copland, Wesley Van Wychen, William Kochtitzky, Robert McNabb, Dorthe Dahl-Jensen
Publikováno v: Journal of Glaciology, Vol 69, Pp 1333-1350 (2023)
This study provides the first comprehensive reconstruction of the dynamics of Iceberg Glacier, located on western Axel Heiberg Island, and reveals detailed observations of a complete surge for the first time in the Canadian Arctic. Historical aerial

Basal stress controls ice-flow variability during a surge cycle of Hagen Bræ, Greenland
Autor: Øyvind A. Winton, Sebastian B. Simonsen, Anne M. Solgaard, Robert McNabb, Nanna B. Karlsson
Publikováno v: Journal of Glaciology, Vol 68, Pp 503-517 (2022)
Basal conditions play an essential role in the dynamics of outlet glaciers, but direct observations at the bed of glaciers are challenging to obtain. Instead, inverse methods can be used to infer basal parameters from surface observations. Here, we u

Kinematics of the exceptionally-short surge cycles of Sít’ Kusá (Turner Glacier), Alaska, from 1983 to 2013
Autor: Andrew Nolan, William Kochtitzky, Ellyn M. Enderlin, Robert McNabb, Karl J. Kreutz
Publikováno v: Journal of Glaciology, Vol 67, Pp 744-758 (2021)
Glacier surges are periodic episodes of mass redistribution characterized by dramatic increases in ice flow velocity and, sometimes, terminus advance. We use optical satellite imagery to document five previously unexamined surge events of Sít’ Kus
