Abstract:
Here we present the triple isotopic composition of atmospheric oxygen (Δ17O of O2) measured from EPICA Dome C (EDC) ice core, Antarctica, over 58.0-150.0, 233.2-238.1, and 445.6-796.3 ka, in order to reconstruct the past global biosphere productivity (Luz et al., 1999). The data were produced between Feb. 2019 and Oct. 2020 at Laboratoire des Sciences du Climat et de l'Environnement (LSCE), Gif-sur-Yvette, France. The air samples trapped in EDC ice cores were extracted and purified by a semi-automated system of LSCE, following the identical principles of Barkan and Luz (2005).

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).
