The data are measurements of carbon dioxide (CO2) from the WAIS Divide Ice Core, WDC06A, Antarctica, dating from 9,000 to 23,000 BP. Refer to Figure 1 for a map of the WAIS Divide area.
Detailed Data Description
The data are measurements of carbon dioxide (CO2) from the WAIS Divide Ice Core, WDC06A, Antarctica, dating from 9,000 to 23,000 BP. Measurements of CO2 were made at Oregon State University using a mechanical crushing system.

Data are in Microsoft Excel (.xlsx
) format.
Data are available on the FTP site in the ftp://sidads.colorado.edu/pub/DATASETS/AGDC/nsidc0651_brook/
directory.
The data file has three worksheets. Refer to Table 1 for a description of each worksheet's contents.

The data file size is 0.7 MB.
The spatial coverage is the WAIS Divide, Antarctica: latitude: 79°467' S; longitude: 112°085' W.
Spatial Resolution
Altitude of the sample area is 1766 m above sea level (a.s.l.). The core depth ranged from 1697 m to 2600 m.
Data were collected 01 June 2011. Paleo temporal coverage ranges from 9,100 to 23,541 years BP (present = 1950).
Refer to Figures 3 and 4 for examples of the data.


Software and Tools
The data can be accessed using Microsoft Excel.
Data Acquisition and Processing
The data are from a 2,800 m section of the West Antarctic Ice Sheet (WAIS) Divide ice core, collected in 2011.
Processing Steps
Measurements of CO2 were made at Oregon State University using a mechanical crushing system. See Ahn et al. for methodology. For more information on the processing of the core samples, see Marcott, et al.
