Results of the Electron Dispersive Spectroscopy (EDS) analysis of subice sediments from the Camp Century Ice core analyzed in 2023.
Authors: Collins C, Perdrial N, Bierman P
Instrument: Oxford Instruments Aztec Elemental Mapping Energy Dispersive X-ray Spectrometer (Geology Department at Middlebury College, Vermont, USA)

For each sample, 2 sites were mapped. For each site, the data consist in:

1. a .docx report for the point-and-shoot EDS analyses
2. several .csv files of individual element maps in matrix format. The element name and emission line(s) are provided in the filename.

Some site also contain a grayscale (electron image) of the area analyzed

Sample naming: Folder: CoreTube_Section-Subsection-site#
Example of name: 1059_5_site1 --> Core tube: 1059, Section: 5, site: 1.

Samples were carbon sputter-coated prior to analysis.
EDS maps were acquired at 20 keV for a minimum of 20 frames totaling 10-minute elapsed time for each multi-elemental map.
Point-and-shoot analyses were acquired at 20 keV for 60 seconds (deadtime corrected).
