https://pastglobalchanges.org/publications/pages-magazines/pages-magazine/138632 We developed a novel hyperspectral line-scan imaging system for ice cores. The system nondestructively captures light-scattering features via dark-field illumination. Its calibrated visible and near-infrared spectral data enhance analysis and archiving, advancing research on stratigraphic impurities, ice dynamics and paleoclimate.https://doi.org/10.22498/pages.33.2.50 “IceSpec: An Ice-Core Hyperspectral Imaging Framework.” 2025.

www.pnas.org/doi/10.1073/pnas.2502681122 with DOI number 10.1073/pnas.2502681122 Paper reports the discovery of ice, that is up to 6 million years old. Isotopic temperatures from this ice indicate progressive cooling over the Pliocene; enigmatic basal ice from the Miocene is characterized by even warmer temperatures and may reflect a relic from the adolescent days of the Antarctic ice […]
