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...

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 an effort to date the layers of interesting physical property and chemical impurities layers. The 2008 S3 chronology is consistent with the independently layer-counted 2011 S1 (Sigl et al., 2015) and D4 core chronologies (McConnell et al., 2007) at >10 volcanic tie points between 1750 and 2008.
