Clean Low-Biomass Procedures and Their Application to Ancient Ice Core Microorganisms [PDF]

open access: yesFrontiers in Microbiology, 2018
Microorganisms in glacier ice provide tens to hundreds of thousands of years archive for a changing climate and microbial responses to it. Analyzing ancient ice is impeded by technical issues, including limited ice, low biomass, and contamination.

Deep ice-core drilling to 800 m at Dome A in East Antarctica

open access: yesAnnals of Glaciology, 2021
A deep ice core was drilled at Dome A, Antarctic Plateau, East Antarctica, which started with the installation of a casing in January 2012 and reached 800.8 m in January 2017. To date, a total of 337 successful ice-core drilling runs have been conducted,

Optimization of hot-water ice-coring drills

open access: yesAnnals of Glaciology, 2021
Hot-water ice-coring drills are often used to recover ice core samples from desirable depths in conjunction with full-scale hot-water drilling systems. However, the recovered cores exhibit varying qualities.

Drilling operations for the South Pole Ice Core (SPICEcore) project

open access: yesAnnals of Glaciology, 2021
Over the course of the 2014/15 and 2015/16 austral summer seasons, the South Pole Ice Core project recovered a 1751 m deep ice core at the South Pole. This core provided a high-resolution record of paleoclimate conditions in East Antarctica during the ...

Core handling, transportation and processing for the South Pole ice core (SPICEcore) project

open access: yesAnnals of Glaciology, 2021
An intermediate-depth (1751 m) ice core was drilled at the South Pole between 2014 and 2016 using the newly designed US Intermediate Depth Drill. The South Pole ice core is the highest-resolution interior East Antarctic ice core record that extends into ...

A stratigraphy-based method for reconstructing ice core orientation

open access: yesAnnals 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

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.
