North Greenland Eemian Ice Drilling (NEEM) 2008 S3 Firn Core Impurity Data
This dataset was used to create a depth-age scale of the NEEM (North Greenland Eemian Ice Drilling) 2008 S3 firn core using annual layer counting of multiple seasonally-varying chemical parameters (McConnell et al., 2007). This depth-age scale was used to date the layers of other NEEM firn cores, in...
