Synchronizing ice cores from the Renland and Agassiz ice caps to the Greenland Ice Core Chronology [PDF]
Journal of Geophysical Research, 2008 Four ice cores from the Agassiz ice cap in the Canadian high arctic and one ice core from the Renland ice cap in eastern Greenland have been synchronized to the Greenland Ice Core Chronology 2005 (GICC05) which is based on annual layer counts in the DYE‐3, GRIP and NGRIP ice cores.

Regional variability of diatoms in ice cores from the Antarctic Peninsula and Ellsworth Land, Antarctica [PDF]
The Cryosphere, 2022 The presence of marine microfossils (diatoms) in glacier ice and ice cores has been documented from numerous sites in Antarctica, Greenland, as well as from sites in the Andes and the Altai mountains, and attributed to entrainment and transport by winds.

Local-scale spatial variability in firn properties in Southwest Greenland
Frontiers in Earth Science, 2022 The increasing mass loss from the Greenland ice sheet is becoming growingly important to present-day global sea level rise. Meltwater export to the ocean may be amplified by near-surface ice layers in firn (i.e., snow that has survived at least one melt ...

Journal of Marine Science and Engineering, 2021 Small-scale variation in the physical and biological properties of sea ice was examined by collecting nine sea ice cores within 1 m2 in a land-fast first-year ice in southwest Greenland in late winter.

A multi-ice-core, annual-layer-counted Greenland ice-core chronology for the last 3800 years: GICC21 [PDF]
Climate of the Past, 2022 Ice-core timescales are vital for the understanding of past climate; hence they should be updated whenever significant amounts of new data become available.

A stratigraphy-based method for reconstructing ice core orientation
Annals of Glaciology, 2021 Ever since the first deep ice cores were drilled, it has been a challenge to determine their original, in-situ orientation. In general, the orientation of an ice core is lost as the drill is free to rotate during transport to the surface. For shallow ice

Age ranges of the Tibetan ice cores with emphasis on the Chongce ice cores, western Kunlun Mountains [PDF]
The Cryosphere, 2018 An accurate chronology is the essential first step for a sound understanding of ice core records. However, dating ice cores drilled from the high-elevation glaciers is challenging and often problematic, leading to great uncertainties.

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 ...

On the occurrence of annual layers in Dome Fuji ice core early Holocene ice [PDF]
Climate of the Past, 2015 Whereas ice cores from high-accumulation sites in coastal Antarctica clearly demonstrate annual layering, it is debated whether a seasonal signal is also preserved in ice cores from lower-accumulation sites further inland and particularly on the East ...

Apparent discrepancy of Tibetan ice core δ18O records may be attributed to misinterpretation of chronology [PDF]
The Cryosphere, 2019 Ice cores from the Tibetan Plateau (TP) are widely used for reconstructing past climatic and environmental conditions that extend beyond the instrumental period.
