Applied Glaciology—the Utilization of Ice and Snow in Arctic Operations [PDF]

open access: yesJournal of Glaciology, 1960
AbstractIn addition to field observations and quantitative analyses of natural phenomena, an opportunity exists for the application of glaciological knowledge. Major problems preventing the widespread use of ice and snow as structural materials are related to processing methods, properties of ice and snow, and deterioration during the melt season ...

Progress toward globally complete frontal ablation estimates of marine-terminating glaciers

open access: yesAnnals of Glaciology, 2022
Knowledge of frontal ablation from marine-terminating glaciers (i.e., mass lost at the calving face) is critical for constraining glacier mass balance, improving projections of mass change, and identifying the processes that govern frontal mass loss ...

Modelling last glacial cycle ice dynamics in the Alps [PDF]

open access: yesThe Cryosphere, 2018
The European Alps, the cradle of pioneering glacial studies, are one of the regions where geological markers of past glaciations are most abundant and well-studied.

A Roadmap for Using Hybridisation Capture-Based Target Enrichment of Ancient Environmental DNA in Palaeoecology. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Recovering ancient DNA from environmental samples is transforming the way we understand historical ecosystems. While high‐throughput sequencing of the total DNA in environmental samples (shotgun metagenomic sequencing) reveals the taxonomic contents of these samples, the genetic signals of some taxa (e.g., eukaryotes) can be weak compared to ...

Using a Web Map Service to map Little Ice Age glacier extents at regional scales

open access: yesAnnals of Glaciology, 2023
Extending the record of glacier area changes into the past improves our understanding of climate change impacts. Although analogue maps showing historic glacier extents are abundant, digital outlines from before the satellite era are sparse as the ...

Recent trends in melting conditions on the Antarctic Peninsula and their implications for ice-sheet mass balance and sea level [PDF]

open access: yes, 2006
Long-term records from meteorological stations on the Antarctic Peninsula show strong rising trends in the annual duration of melting conditions. In each case, the trend is statistically significant and represents a major increase in the potential for ...

Basal seismicity of the Northeast Greenland Ice Stream

open access: yesJournal of Glaciology, 2020
Seismic studies of glaciers yield insights into spatio-temporal processes within and beneath glaciers on scales relevant to flow and deformation of the ice.

Chemical and isotopic switching within the subglacial environment of a high Arctic glacier. [PDF]

open access: yes, 2006
Natural environmental isotopes of nitrate, sulphate and inorganic carbon are discussed in conjunction with major ion chemistry of subglacial runoff from a High Arctic glacier, Midre Lovénbreen, Svalbard. The chemical composition of meltwaters is observed

Eurasian ice-sheet dynamics and sensitivity to subglacial hydrology

open access: yesJournal of Glaciology, 2017
Ice-stream dynamics are strongly controlled by processes taking place at the ice/bed interface where subglacial water both lubricates the base and saturates any existing, underlying sediment. Large parts of the former Eurasian ice sheet were underlain by
