Tracking the Filling, Outburst Flood and Resulting Subglacial Water Channel From a Large Canadian Arctic Subglacial Lake
GEOPHYSICAL RESEARCH LETTERS
07 october 2024
Laurence Gray, Karen E. Alley, Luke Copland, Chris...
We use digital elevation models (DEMs) and ICESat‐2 data to study the filling and outflow from a large subglacial lake under Manson Icefield ...

Closing Greenland's Mass Balance: Frontal Ablation of Every Greenlandic Glacier From 2000 to 2020
GEOPHYSICAL RESEARCH LETTERS
07 september 2023
William H. Kochtitzky, Luke Copland, Michalea D. K...
In Greenland, 87% of the glacierized area terminates in the ocean, but mass lost at the ice‐ocean interface, or frontal ablation, has not yet...

Retreat of Northern Hemisphere Marine‐Terminating Glaciers, 2000–2020
GEOPHYSICAL RESEARCH LETTERS
31 january 2022
William H. Kochtitzky, Luke Copland
We mapped the terminus position for every marine‐terminating glacier in the Northern Hemisphere for 2000, 2010, and 2020, including the Green...
Gftt: an open-source tool for evaluating remotely sensed glacier velocity products
COMMUNITY TOOLS AND PRODUCTS FOR CRYOSPHERE DISCOVERY AND APPLICATION II POSTER
cryosphere | 17 december 2021
Whyjay Zheng, Shashank Bhushan, Maximillian S. Van...
Glacier velocity reflects the dynamics of ice flow, and its change over time serves a key role in predicting the future sea-level rise. Glacier featur...

2020 Dickinson Sidkap Hackweek: Glacier changes near Canada’s most northern community, Grise Fiord, Nunavut, Canada
OBSERVATIONS AND MODELS OF GLACIER CHANGE III POSTERS
cryosphere | 11 december 2020
Isabel Ruff, William H. Kochtitzky, Benjamin R. Ed...
Grise Fiord is the northernmost community in Canada and depends on glacier meltwater for much of its freshwater supply. In 1959, the peninsula on whic...
