Abstract:
Compilation of improved CH4 data derived from the European Project for Ice Coring in Antarctica (EPICA) Dome C ice core covering Marine Isotope Stage (MIS) 9e - 12a. For this compilation, vertically contiguous (i.e. directly neighbouring) replicate measurements of the source CH4 dataset Nehrbass-Ahles et al. (2020) (https://doi.org/10.1594/PANGAEA.914907) have been averaged and are reported as single data points.

Latitude: -75.100000 * Longitude: 123.350000
Date/Time Start: 1993-01-01T00:00:00 * Date/Time End: 2004-12-31T00:00:00

Event(s):
EDC (EPICA Dome C) * Latitude: -75.100000 * Longitude: 123.350000 * Date/Time Start: 1993-01-01T00:00:00 * Date/Time End: 2004-12-31T00:00:00 * Elevation: 3233.0 m * Recovery: 3300 m * Location: Dome C, Antarctica * Campaign: Dome C * Method/Device: Ice drill (ICEDRILL) * Comment: Drill site is 56 km from the site of a previous Dome C core that provided records extending into the last glacial period, and 560 km from the site of the Vostok cores. The completion of the Dome C core was delayed when the first drilling became stuck at 788 m in 1999 (EDC96).
