Firn density and ice content at sites along the west EGIG line, Greenland, 2018 and 2019

This archive contains data collected at sites located along the lower elevation portion of the Expéditions Glaciologiques Internationales au Groenland (EGIG) line, western Greenland Ice Sheet. The data include the physical stratigraphy measured in firn cores extending to depths of up to ~30 meters (m) with measurements of firn density and refrozen ice content. The data were collected as part of a project funded by the U.S. National Science Foundation. Each of the study sites is in the Greenland Ice Sheet’s Percolation Zone. The data were collected during May-June of 2018 and 2019. This dataset will be associated with additional datasets collected as part of a NSF Arctic Observing Network project, including physical stratigraphy and density measured in ice cores and firn temperature time series measured in core holes, as they become available in future years.
