Group: Summary
This data set includes a time scale for the Vostok ice core, retrieved from
Vostok Station on the East Antarctic Plateau. This chronology is derived by
orbitally tuning to molecular oxygen to nitrogen (O2/N2)
ratios in occluded air for depths deeper than 1550 m (greater than 112,000
years old), and by gas correlation to the Greenland Ice Sheet Project 2
(GISP2) chronology for the ice core section that is shallower than 1422 m
(less than 102,000 years old). Because of poor gas preservation in air bubbles
in shallower depths, investigators could only constrain the Vostok chronology
for the section deeper than 1550 m by O2/N2. Thus for
the shallower section of the core, they synchronized the Vostok delta
oxygen-18 (δ18O) and methane (CH4) measurements to
those of the GISP2 to obtain the chronology (see Bender, et al. 2006). Note,
CH4 data are not included in this data set.
Investigators analyzed the O2/N2 and the
δ18O record ratios for approximately the past
115,000 to 400,000 years in the Vostok ice core. They combined new
measurements for O2/N2 and δ18O with
data from Bender (2002) and Petit, et al. (1999), respectively.
Data are in Microsoft Excel format and are available via FTP.
