An Ice Core Slice Scanning Tool based on Line-scan Camera [PDF]

open access: yesE3S Web of Conferences, 2021
The ice core from polar ice sheet is one of the most valuable archives of past climate and environment. The ice core visual stratigraphy, based on optical scanning analysis, provides the most intuitive information of the micro-particles and/or air ...

Inclusions in ice layers formed by melting and refreezing processes in a Greenland ice core

open access: yesJournal of Glaciology, 2023
In recent decades, surface melting on the inland Greenland ice sheet has increased, leading to significant meltwater-refreezing in the snow and firn.

Antarctic subglacial drilling rig: Part II. Ice and Bedrock Electromechanical Drill (IBED)

open access: yesAnnals 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.

Identification of core ion cyclotron instabilities on HL-2A tokamak

open access: yesNuclear 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.

A stratigraphic link across 1100 km of the Antarctic Ice Sheet between the Vostok ice-core site and Titan Dome (near South Pole) [PDF]

open access: yes, 2000
Isochronous internal ice-sheet layering, measured from airborne 60 MHz radar, was traced between Lake Vostok and the Titan Ice Dome (100 km from South Pole Station), Antarctica. Three layers were selected between Ridge B and Titan Dome, and between Ridge

The future of ice coring: International Partnerships in Ice Core Sciences (IPICS) [PDF]

open access: yesPAGES news, 2006
Ice cores provide information about past climate and environmental conditions on timescales from decades to hundreds of millennia, and direct records of the composition of the atmosphere. As such, they are cornerstones of global change research. For example, ice cores play a central role in showing how closely climate and greenhouse gas concentrations ...

High-resolution atmospheric cadmium record for AD 1776–2004 in a high-altitude ice core from the eastern Tien Shan, central Asia

open access: yesAnnals of Glaciology, 2016
Two ice cores drilled to the bottom were recovered from Miaoergou flat-topped glacier (43°03'19“N, 94°19'21“E; 4512 ma.s.l.), eastern Tien Shan, central Asia, in 2005.

New modeling of the Vostok ice flow line and implication for the glaciological chronology of the Vostok ice core [PDF]

open access: yes, 2004
We have used new spaceborne (elevation) and airborne (ice thickness) data to constrain a 2D1/2 model of snow accumulation and ice flow along the Ridge B-Vostok station ice flow line (East Antarctica).

Variations in atmospheric dust loading since AD 1951 recorded in an ice core from the northern Tibetan Plateau

open access: yesAnnals of Glaciology, 2016
An ice core was extracted from the Zangser Kangri (ZK) ice field in the northern Tibetan Plateau (NTP), a location with limited instrumental and proxy records. In this paper, we present a continuous high–resolution dust concentration time series spanning
