Paleogene marine and terrestrial development of the West Antarctic Rift System: Biomarker Data Set

Abstract: This data set includes biomarker data presented in Paleogene marine and terrestrial development of the West Antarctic Rift System. Included in the alkane sheet are the Terrestrial/aquatic (T/A) n-alkane ratio, total long (C27-C33)- and mid-chain (C23 and C25) n-alkane concentrations in units of ng alkanes per g sediment extracted, and the n-alkane average chain-length (ACL). Included in the glycerol dialkyl glycerol tetraethers (GDGT) sheet are the TEX86 sea surface temperature estimates with multiple calibrations discussed in the text, the MBT’5ME mean annual air temperature estimates, the branched and isoprenoid tetraether (BIT) index.

摘要：本数据集涵盖西南极裂谷系（West Antarctic Rift System）古近纪海相与陆相演化过程中的生物标志物数据。正构烷烃工作表中包含陆源/水生（T/A）正构烷烃（n-alkane）比值、总长链（C27~C33）及中链（C23、C25）正构烷烃浓度（单位：每克萃取沉积物中正构烷烃的纳克数），以及正构烷烃平均链长（ACL）。甘油二烷基甘油四醚（GDGT）工作表中包含文中讨论的多种校准方法对应的TEX86海表温度估算值、MBT’5ME年平均气温估算值，以及支链与类异戊二烯四醚（BIT）指数。
