View Catalog Page

Entry ID

NSIDC-0110

Summary

This data set consists of electron microprobe geochemical analyses of glass shards sampled from Siple Dome and Taylor Dome ice cores during the 1999-2000 field season. Geochemical data are in tab-delimited ASCII and Excel formats. Backscattered electron images of tephra samples are in TIFF format. Data are available via ftp.
