Responses of the Pine Island and Thwaites glaciers to melt and sliding parameterizations

I Joughin, D Shapero, P Dutrieux - The Cryosphere, 2024 - tc.copernicus.org
The Pine Island and Thwaites glaciers are the two largest contributors to sea level rise from
Antarctica. Here we examine the influence of basal friction and ice shelf basal melt in …

[HTML][HTML] A new vertically integrated MOno-Layer Higher-Order (MOLHO) ice flow model

T Dias dos Santos, M Morlighem, D Brinkerhoff - The Cryosphere, 2022 - tc.copernicus.org
Numerical simulations of ice sheets rely on the momentum balance to determine how ice
