Evaluating Greenland glacial isostatic adjustment corrections using GRACE, altimetry and surface mass balance data

Environmental Research Letters, 2014
Glacial isostatic adjustment (GIA) represents a source of uncertainty for ice sheet mass balance estimates from the Gravity Recovery and Climate Experiment (GRACE) time-variable gravity measurements.

Synthesis of field and satellite data to elucidate recent mass balance of five ice rises in Dronning Maud Land, Antarctica

Frontiers in Earth Science, 2022
We investigated mass balance changes over five ice rises in the last few decades near Fimbul and Nivl ice shelves in central Dronning Maud Land. We use the Input-Output Method constrained using field-based geophysical measurements conducted during the ...

A note on hysteresis in glaciology

Applied Mathematics Letters, 2000
AbstractRecent studies on the mechanism governing the Laurentide ice sheet oscillations of the Last Ice Age focus on the most critical effect of the basal hydraulic processes enhanced when the ice is sliding along soft deformable beds. To understand the import of this, we consider Fowler and Johnson's 0-D hydrological flow model describing the sudden ...

Modeling of ocean‐induced ice melt rates of five west Greenland glaciers over the past two decades

Geophysical Research Letters, 2016
High‐resolution, three‐dimensional simulations from the Massachusetts Institute of Technology general circulation model ocean model are used to calculate the subaqueous melt rate of the calving faces of Umiamako, Rinks, Kangerdlugssup, Store, and ...

Mapping Surface Flow Velocity of Glaciers at Regional Scale Using a Multiple Sensors Approach

Remote Sensing, 2019
We explore and compare the capabilities and limitations of different optical sensors (Sentinel-2/ESA, Landsat 7/8/USGS, Ven μ s/CNES-ISA, Pléiades/AirbusD&S and Planet Labs images) for mapping the surface speeds of mountain glaciers on ...

A multidimensional approach to knowledge coproduction in glaciology

Journal of Glaciology
This work presents a reflection on the meaning and significance of knowledge coproduction in the field of glaciology. We start by invoking the paradigm of Structure–Form–Environment Interplay (SFEI) to formulate a generalised definition of glaciology ...

Structural glaciology of Isunguata Sermia, West Greenland

Journal of maps, 2018
We present a 1:42,000 scale map of Isunguata Sermia, a land-terminating outlet glacier draining the western-sector of the Greenland Ice Sheet. Structure-from-Motion software applied to ∼3,600 aerial images collected by a fixed-wing unmanned aerial ...
