Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Development of the British Antarctic Survey Rapid Access Isotope Drill

Journal of Glaciology, 2019
The British Antarctic Survey Rapid Access Isotope Drill is an innovative new class of electromechanical ice drill, which has recently been used to drill the deepest dry hole drilled by an electromechanical auger drill. The record-breaking depth of 461.58

Initial psychometric evaluation of the canine brief pain inventory in a Danish sample of dogs with pain related to osteoarthritis.

Research in Veterinary Science
INTRODUCTION Osteoarthritis (OA) is the most diagnosed arthropathy in dogs. Since the characteristic manifestation of OA is pain, clinical metrology instruments for OA should detect observable outcomes related to OA pain and be validated in the ...

Lidar-based snow monitoring from aerial lifts: Gondola deployment in the Austrian Alps

Journal of Glaciology
Monitoring snow distribution in alpine terrain is critical for hydrology, avalanche safety, and climate research, yet traditional surveys are costly, hazardous, and spatially sparse.

Calving of Fuerza Aérea Glacier (Greenwich Island, Antarctica) observed with terrestrial laser scanning and continuous video monitoring

Journal of Glaciology, 2016
A short-term series of quantitative observations of calving activity of Fuerza Aérea Glacier (Greenwich Island, the South Shetland Islands, Antarctica) was conducted in order to test new methods of monitoring calving.

Assessing the applicability of terrestrial laser scanning for mapping englacial conduits

Journal of Glaciology, 2018
The morphology of englacial drainage networks and their temporal evolution are poorly characterised, particularly within cold ice masses. At present, direct observations of englacial channels are restricted in both spatial and temporal resolution ...

Development of a Video Consultation Patient-Satisfaction Questionnaire (vCare-PSQ): A Cross-Sectional Explorative Study

JMIR Formative Research
Background Since the COVID-19 pandemic, the use of video consultation (VC) in primary care has expanded considerably in many countries. VC and other telehealth formats are often touted as a solution to improved health care access, with numerous studies ...

Quantifying bioalbedo: a new physically based model and discussion of empirical methods for characterising biological influence on ice and snow albedo

, 2017
. The darkening effects of biological impurities on ice and snow have been recognised as a control on the surface energy balance of terrestrial snow, sea ice, glaciers and ice sheets.

Spectral signatures of submicron scale light-absorbing impurities in snow and ice using hyperspectral microscopy

Journal of Glaciology, 2018
Light-absorbing impurities (LAI) can darken snow and ice surfaces, reduce snow/ice albedo and accelerate melt. Efforts to allocate the relative contribution of different LAI to snow/ice albedo reductions have been limited by uncertainties in the optical ...
