Estimating ice discharge of the Antarctic Peninsula using different ice-thickness datasets

open access: yesAnnals of Glaciology, 2023
The Antarctic Peninsula Ice Sheet (APIS) has become a significant contributor to sea-level rise over recent decades. Accurately estimating the ice discharge from the outlet glaciers of the APIS is crucial to quantify the mass balance of the Antarctic ...

A comparison of contemporaneous airborne altimetry and ice-thickness measurements of Antarctic ice shelves

open access: yesJournal of Glaciology, 2023
Estimates of ice shelf mass loss are typically based on surface height measurements, assuming hydrostatic equilibrium and estimated firn thickness.

Slope estimation influences on ice thickness inversion models: a case study for Monte Tronador glaciers, North Patagonian Andes

open access: yesJournal of Glaciology, 2020
Glacier ice thickness is crucial to quantifying water resources in mountain regions, and is an essential input for ice-flow models. Using a surface velocity inversion method, we combine ice thickness measurements with detailed surface elevation and ...

Impact crater morphology and the structure of Europa's ice shell

open access: yes, 2017
We performed numerical simulations of impact crater formation on Europa to infer the thickness and structure of its ice shell. The simulations were performed using iSALE to test both the conductive ice shell over ocean and the conductive lid over warm ...

Analysis of the Variability and Influencing Factors of Ice Thickness during the Ablation Period in Qinghai Lake Using the GPR Ice Monitoring System

open access: yesRemote Sensing, 2022
As a reliable indicator of regional climate change, the growth and decline of lake ice thickness affect the regional intra–annual heat and energy balance. In this study, a ground-penetrating radar (GPR) ice monitoring system, located approximately 1.7 km
