Ice core hot-flid drilling

Antarctic Record, 1994
Fast hole production is possible using ice core hot-fluid drilling. The present paper describes a method for calculation of drill penetration rate dependent on the fluid flux, fluid temperature, physical properties of fluid, size of hot-fluid drill head ...

Effects of ENSO on the major ion record of a Qomolangma (Mount Everest) ice core

Annals of Glaciology, 2016
Correlations between a 1000 year record of the major ions in a 108.83 m ice core from East Rongbuk Glacier (28°01’N, 86°58’E; 6518ma.s.l.) on the northeast slope of Qomolangma (Mount Everest) and the Southern Oscillation Index (SOI) were examined to ...

Climate instability during the last interglacial period recorded in the GRIP ice core

, 1993
Isotope and chemical analyses of the GRIP ice core from Summit, central Greenland, reveal that climate in Greenland during the last interglacial period was characterized by a series of severe cold periods, which began extremely rapidly and lasted from ...

Past rates of accumulation in central West Antarctica [PDF]

, 2004
The spatial variation in ice accumulation is critical to the form and stability of ice sheets. In West Antarctica, knowledge of present ice accumulation rates is restricted to sparse measurements and interpolations across data free regions, while ...

Seasonal evolution of granular and columnar sea ice pore microstructure and pore network connectivity

Journal of Glaciology, 2022
Sea-ice pore microstructure constrains ice transport properties, affecting fluid flow relevant to oil-in-ice transport and biogeochemical processes. Motivated by a lack of pore microstructural data, in particular for granular ice and across the seasonal ...

The Global Stratotype Section and Point (GSSP) for the base of the Holocene Series/Epoch (Quaternary System/Period) in the NGRIP ice core

, 2008
The Greenland ice core from NorthGRIP (NGRIP) contains a proxy climate record across the Pleistocene– Holocene boundary of unprecedented clarity and resolution.

Characterizing Spatial Variability of Ice Algal Chlorophyll a and Net Primary Production between Sea Ice Habitats Using Horizontal Profiling Platforms

Frontiers in Marine Science, 2017
Assessing the role of sea ice algal biomass and primary production for polar ecosystems remains challenging due to the strong spatio-temporal variability of sea ice algae.

Initial results from geophysical surveys and shallow coring of the Northeast Greenland Ice Stream (NEGIS) [PDF]

The Cryosphere, 2014
The Northeast Greenland Ice Stream (NEGIS) is the sole interior Greenlandic ice stream. Fast flow initiates near the summit dome, and the ice stream terminates approximately 1000 km downstream in three large outlet glaciers that calve into the Greenland ...

Origin and significance of 'dispersed facies' basal ice: Svínafellsjökull, Iceland [PDF]

, 2010
Dispersed facies basal ice - massive (i.e. structureless) ice with dispersed debris aggregates - is present at the margins of many glaciers and, as a product of internal glacial processes, has the potential to provide important information about the ...
