Reconstruction of the global oxygen biosphere productivity based on Δ17O of O2 measurements from Vostok, GISP2 and EDC ice cores over the last 450 ka

Reconstruction of the global oxygen biosphere productivity over the last 445 ka based on measurements of Δ17O of O2 in Vostok, GISP2 and Epica Dome C ice cores and new correction factors compared to the previous record of Blunier et al., 2012

基于沃斯托克（Vostok）、GISP2和EPICA Dome C冰芯中氧气的Δ¹⁷O（Δ17O）测量值，以及与Blunier等人2012年发布的既往记录对比得到的新校正因子，本数据集重建了过去44.5万年的全球氧生物圈生产力。
