This document describes the columns of the Central West Antarctic Glaciochemistry data sets.
The glaciochemical records represent the major ionic species present in Antarctic snow: Na+, K+, Mg2+, Ca2+, Cl-, NO3- and SO42-.
| Column 1 | Top Depth (in meters) |
| Column 2 | Bottom Depth (in meters) |
| Column 3 | Top Time (in years before 2000 A.D.) |
| Column 4 | Bottom Time (in years before 2000 A.D.) |
| Column 5 | Mid Year (decimal year of midpoint of the specific section of core) |
| Column 6 | Na+ Sodium (ppb - parts per billion) |
| Column 7 | K+ Potassium (ppb) |
| Column 8 | Mg2+ Magnesium (ppb) |
| Column 9 | Ca2+ Calcium (ppb) |
| Column 10 | Cl- Chloride (ppb) |
| Column 11 | NO3- Nitrate (ppb) |
| Column 12 | SO42- Sulfate (ppb) |
