Ethane measurements in air extracted from Greenland and Antarctic ice cores, Version 1.0

This dataset contains the results of ethane (C2H6) analysis in air extracted from 27 ice core samples from Summit, Greenland (GISP2B ice core) and 33 samples from West Antarctic Ice Sheet Divide, Antarctica (WDC-05A ice core). The data is in Excel (.xlsx) format with data from the two sites provided in separate worksheets named after the ice cores. In addition to ethane, dichlorodifluoromethane (CFC-12) measurements are also reported for all samples. The presence of CFC-12 can indicate presence of modern air in an ice core sample.
