Variations in hydraulic efficiency of the subglacial drainage landsystem control surging and streaming regimes of outlet glaciers

open access: yesJournal of Glaciology, 2023
Surging and streaming of glaciers are modulated by meltwater availability and pressure which controls mechanical coupling at their beds. Using laboratory-scale experimental modelling and palaeoglaciological mapping, we explore how subglacial drainage ...

Melting dynamics of ice in the mesoscopic regime [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance The complete unfolding of the melting process, from the nucleation onset to the achievement of a bulk liquid structure, is not known to date for the timescales and the sizes of the heterogeneities involved. Here, we observe in ice the archetypal H-bonded molecular crystal, the evolution of solid/liquid interfaces generated by the

Crystallisation of the amorphous ices in the intermediate pressure regime [PDF]

open access: yesScientific Reports, 2017
AbstractThe crystallisation behaviour of very high-density amorphous ice (VHDA) and unannealed high-density amorphous ice (uHDA) has been studied in situ by volumetry and ex situ by powder x-ray diffraction in the intermediate pressure range 0.7–1.8 GPa employing different heating rates (0.5, 5 and 30 K min−1).

Changes in the Thickness of Ice Cover on Water Bodies Subject to Human Pressure (Silesian Upland, Southern Poland)

open access: yesFrontiers in Earth Science, 2021
The paper discusses the reasons behind the variation in the thickness of ice on 39 anthropogenic water bodies located in the Silesian Upland (southern Poland). The studies were conducted over the course of three consecutive winter seasons.
