Airborne Validation of ICESat-2 ATLAS Data over Crevassed Surfaces and Other Complex Glacial Environments: Results from Experiments of Laser Altimeter and Kinematic GPS Data Collection from a Helicopter over a Surging Arctic Glacier (Negribreen, Svalbard)

open access: yesRemote Sensing, 2022
The topic of this paper is the airborne evaluation of ICESat-2 Advanced Topographic Laser Altimeter System (ATLAS) measurement capabilities and surface-height-determination over crevassed glacial terrain, with a focus on the geodetical accuracy of ...

Changes in the Structure of the Snow Cover of Hansbreen (S Spitsbergen) Derived from Repeated High-Frequency Radio-Echo Sounding

open access: yesRemote Sensing, 2022
This paper explores the potential of ground-penetrating radar (GPR) monitoring for an advanced understanding of snow cover processes and structure. For this purpose, the study uses the Hansbreen (SW Spitsbergen) records that are among the longest and the

Application of the radionuclide 210Pb in glaciology – an overview

open access: yesJournal of Glaciology, 2020
210Pb is an environmental radionuclide with a half-life of 22.3 years, formed in the atmosphere via radioactive decay of radon (222Rn). 222Rn itself is a noble gas with a half-life of 3.8 days and is formed via radioactive decay of uranium (238U ...

Data assimilation in glaciology [PDF]

open access: yes, 2014
Abstract This chapter addresses an inverse problem in glaciology, namely how to infer a climatic scenario (i.e. how to reconstruct past polar temperature) from ice volume records. Ice volume observations are available from oceanic records, giving information about sea level, and therefore about the amount of water stored in ice sheets ...

PyTrx: A Python-Based Monoscopic Terrestrial Photogrammetry Toolset for Glaciology

open access: yesFrontiers in Earth Science, 2020
Terrestrial time-lapse photogrammetry is a rapidly growing method for deriving measurements from glacial environments because it provides high spatio-temporal resolution records of change.

On ice floe across the Weddell Sea (thirty years since the opening of the first Antarctic drifting station)

open access: yesЛëд и снег, 2022
The year 2022 marks the 30th anniversary from operation of the Russian-American drifting station in the Antarctic. It was first experience of organizing a research station on sea ice in the South Polar exploration. Russia and the U.S.

The K-transect in west Greenland: Automatic weather station data (1993–2016)

open access: yesArctic, Antarctic, and Alpine Research, 2018
We present twenty-three years (1993–2016) of automatic weather station (AWS) data, collected along the K-transect near Kangerlussuaq in west Greenland. The transect runs from east to west, roughly perpendicular to the ice sheet edge at about 67° N. The K-

Distributed acoustic sensing of microseismic sources and wave propagation in glaciated terrain

open access: yesNature Communications, 2020
In this study, Walter and colleagues deploy a 1 km long fiber optics cable on a glacier surface. Via the use of distributed acoustic sensing, the authors are capable of monitoring glacier dynamics and Alpine mass movements.

Grounding‐Zone Flow Variability of Priestley Glacier, Antarctica, in a Diurnal Tidal Regime

open access: yesGeophysical Research Letters, 2021
Tidal modulation of ice streams and their adjacent ice shelves is a real‐world experiment to understand ice‐dynamic processes. We observe the dynamics of Priestley Glacier, Antarctica, using Terrestrial Radar Interferometry (TRI) and GNSS.
