This document includes ice drill site information and ice core repository information for select ice cores retrieved between 1958 and 2022. Included data are not representative of all ice cores drilled during this time period, nor are they representative of all ice core samples collected and maintained by all of the contributing programs and facilities. Data are presented as they were provided by contributing facilities in 2022, when they were used to generate a figure for an article in Past Global Changes Magazine (doi.org/10.22498/pages.30.2.98). The data describe ice core drilling sites (latitude, longitude, elevation, site name), ice core samples (bottom depth, bottom age, core diameter, core completion date, corresponding publications), and ice core storage facilities (latitude, longitude, name). Contributing facilities include the following: Alfred Wegener Institute (Germany), Australian Antarctic Division (Australia), Australian Antarctic Program Partnership (Australia), Byrd Polar Center - University of Ohio (United States of America), Canadian Ice Core Lab (Canada), Chiba University (Japan), Commonwealth Scientific and Industrial Research Organization (Australia), Institute of Environmental Geosciences - University of Grenoble (France), Institute of Low Temperature Science - University of Hokkaido (Japan), Institute of Polar Science and Engineering - Jilin University (China), Karakoram International University (Pakistan), Lanzhou Institute of Glaciology and Geocryology (China), Nagoya University (Japan), National Institute of Polar Research (Japan), National Science Foundation Ice Core Facility (United States of America), New Zealand National Ice Core Facility (New Zealand, Physics of Ice Climate and Earth - University of Copenhagen (Denmark), Polar Research Institute of China (China), Research Institute for Humanity and Nature (Japan), and Tibet University. We are grateful to each of these facilities for contributing details of their ice core collections for this work. Electronic data accessibility and sample request procedures for a few of these facilities of which the authors are aware are listed below. Australia: data can be obtained from the Australian Antarctic Data Centre (https://data.aad.gov.au); access to ice from the Australian Antarctic Program is via application (see https://www.antarctica.gov.au/science/information-for-scientists/) Denmark: data can be obtained from www.iceandclimate.nbi.ku.dk/data; the ice sampling request procedure is listed here: https://www.iceandclimate.nbi.ku.dk/data/samplingprocedure/ United States: many ice core datasets can be found at the NOAA World Data Center (https://www.ncei.noaa.gov/products/paleoclimatology/ice-core); the allocation policy for ice core samples can be found here: https://icecores.org/policy.
