IceSpec: An ice-core hyperspectral imaging framework

Payne Institute Earth Observation Group Senior Research Associate Mikhail Zhizhin and research associates write about how IceSpec, a novel hyperspectral line-scan imaging system for ice cores, 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.  October 29, 2025.
