Antarctic subglacial drilling rig: Part II. Ice and Bedrock Electromechanical Drill (IBED)
Annals of Glaciology, 2021 A new, modified version of the cable-suspended Ice and Bedrock Electromechanical Drill (IBED) was designed for drilling in firn, ice, debris-rich ice and rock.

Proceedings of the National Academy of Sciences, 1997 Air trapped in glacial ice offers a means of reconstructing variations in the concentrations of atmospheric gases over time scales ranging from anthropogenic (last 200 yr) to glacial/interglacial (hundreds of thousands of years). In this paper, we review the glaciological processes by which air is trapped in the ice and discuss ...

Identification of core ion cyclotron instabilities on HL-2A tokamak
Nuclear Fusion, 2023 Instabilities in multiplies of ion cyclotron frequency range are identified and termed as core ion cyclotron emission (ICE) in recent HL-2A neutral beam injection heated experiments.

Upstream flow effects revealed in the EastGRIP ice core using Monte Carlo inversion of a two-dimensional ice-flow model [PDF]
The Cryosphere, 2021 The Northeast Greenland Ice Stream (NEGIS) is the largest active ice stream on the Greenland Ice Sheet (GrIS) and a crucial contributor to the ice-sheet mass balance.

A glaciochemical study of the 120 m ice core from Mill Island, East Antarctica [PDF]
Climate of the Past, 2017 A 120 m ice core was drilled on Mill Island, East Antarctica (65°30′ S, 100°40′ E) during the 2009/2010 Australian Antarctic field season. Contiguous discrete 5 cm samples were measured for hydrogen peroxide, water stable isotopes, and trace ion ...

Burning-derived vanillic acid in an Arctic ice core from Tunu, northeastern Greenland [PDF]
Climate of the Past, 2018 In this study, vanillic acid was measured in the Tunu ice core from northeastern Greenland in samples covering the past 1700 years. Vanillic acid is an aerosol-borne aromatic methoxy acid, produced by the combustion of lignin during biomass burning ...

A multi-millennial record of rock glacier ice chemistry (Lazaun, Italy)
Frontiers in Earth Science, 2023 Active rock glaciers—known as mixtures of unconsolidated debris with interstitial ice, ice lenses or a core of massive ice—are widespread indicators of mountain permafrost. The age of a frozen rock glacier core in the Central European Alps (Lazaun, Italy)

Diffusive equilibration of N2, O2 and CO2 mixing ratios in a 1.5-million-years-old ice core [PDF]
The Cryosphere, 2014 In the framework of the International Partnerships in Ice Core Sciences, one of the most important targets is to retrieve an Antarctic ice core that extends over the last 1.5 million years (i.e.
