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

Annals 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 ...
