Earth's Future, Volume 10, Issue 12, December 2022., 2022 Abstract Anthropogenic greenhouse gas emissions are causing unprecedented changes to the climate. In 2015, at the United Nations (UN) Conference of the Parties in Paris, France, countries agreed to limit the global mean temperature (GMT) increase to 2°C above preindustrial levels, and to pursue efforts to limit warming to 1.5°C.

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]
, 2012 Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

Journal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022 Abstract Many meandering rivers migrate, at rates that vary both along‐stream and inversely with the observation interval. Many numerical models have been developed to predict this migration; their success is usually evaluated statistically or by qualitative comparison to observations in map view.

DISCO: An optical instrument to calibrate neutrino detection in complex media [PDF]
arXiv, 2023 We present a conceptual design of a high-performance camera system with applications to neutrino detectors, deep sea exploration, and glaciology. The design combines ultra-sensitive cameras with a number of well-calibrated light sources enclosed in a pressure vessel.

Suitability of a constant air temperature lapse rate over an Alpine glacier: testing the Greuell and Böhm model as an alternative [PDF]
, 2013 Near-surface air temperature, typically measured at a height of 2 m, is the most important control on the energy exchange and the melt rate at a snow or ice surface.

Repeating Low Frequency Icequakes in the Mont‐Blanc Massif Triggered by Snowfalls
Journal of Geophysical Research: Earth Surface, Volume 127, Issue 12, December 2022., 2022 Abstract Deformation mechanisms of glaciers are highly sensitive to basal temperature; the motion of temperate glaciers is dominated by basal slip while cold‐based glaciers deform mainly by internal creep. While basal slip is usually aseismic, unstable slip sometimes occurs and can be detected by seismometers.

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 ...

Journal of Advances in Modeling Earth Systems, 2021 Ice shelf fracture is responsible for roughly half of Antarctic ice mass loss in the form of calving and can weaken buttressing of upstream ice flow.

Present and future impact of snow cover and glaciers on runoff from mountain regions [PDF]
, 2010 The aim of this contribution is to show how snow- and glaciermelt influence runoff today and in the future under the assumption that global warming continues.

Boreas, Volume 52, Issue 1, Page 109-123, January 2023., 2023 The recurrent latent‐heat polynya characterizing Storfjorden (Svalbard, Norway) triggers seasonal formation of thin first‐year sea ice. This leads to the production of dense, salty, and corrosive brines that cascade towards the sea floor and mix with shelf waters. The bottom topography of the fjord is responsible for the retention of these dense waters
