Density and ice layer stratigraphy in 24 shallow firn cores from Southwest Greenland, 2017 - 2019
Observations of near-surface firn density and ice layer stratigraphy collected on the Greenland ice sheet are rare. This dataset contains information about twenty-four shallow firn cores drilled in the percolation zone in southwest Greenland between 2017 and 2019. Seven cores ranged between 2.9 and...

Observations of near-surface firn density and ice layer stratigraphy collected on the Greenland ice sheet are rare. This dataset contains information about twenty-four shallow firn cores drilled in the percolation zone in southwest Greenland between 2017 and 2019. Seven cores ranged between 2.9 and 6.3 meter (m) depth, with the remaining seventeen cores extending to 10–27 m depths. Each core has data on density, ice layer stratigraphy, and type of material (i.e. snow, firn, or ice). Quality control was performed on all data to replace erroneous data. More details including uncertainty analysis are provided in the method section and in Rennermalm et. al., (2021).
