Interannual and seasonal evolution of supraglacial drainage systems on Nivlisen Ice Shelf, East Antarctica

This dataset provides mapped surface meltwater and supraglacial drainage components on Nivlisen Ice Shelf, East Antarctica. It includes interannual datasets as well as seasonal observations from the 2018-2019 melt season. Surface meltwater is provided as polygon shapefiles, and supraglacial channels/drainage components are provided as polyline shapefiles. Mapping methods and data processing are described in the associated publication. Users of this dataset are requested to cite the associated article when using these data in publications, presentations, analyses, or other research outputs: https://doi.org/10.5194/egusphere-2025-5562, 2026
