Millennial And Orbital-scale Variability In A Fifty Four,000-year Document Of Total Air Content From The South Pole Ice Core

Reference Bassinot, Lebeyrie, Vincent, Quidelleur, Shackleton and LancelotCuffey and Vimeux (2001) give a great illustration of how delicate the small print of isotope paleorecords are to changes in their water-vapor sources and, hence, to their origins. Thus, the above estimates could also be understood if the ages from two completely different series with statistically unbiased perturbations (errors) of 4–6 kyr are intercompared. These conclusions are important and permit us to make use of the GMTS and DHVTS age–depth correlation factors to constrain the ice-flow model in the Vostok space on common, with minimum systematic errors in ice age predictions to a depth of 3350 m.

“Light” oxygen-16, with eight protons and 8 neutrons, is the commonest isotope present in nature, followed by a lot lesser quantities of “heavy” oxygen-18, with eight protons and 10 neutrons. SST alignment to Antarctic temperature variations was made at marked transitions within the temperature record, similar to Antarctic Isotopic Maxima32, the onset of the early and late deglacial warming, or the start of the Antarctic Cold Reversal. Knowledge of history, including the history of papers published within the Journal of Glaciology, reveals that ice-core science is indeed dependable. The value of disciplinary journals such as the Journal of Glaciology is proven very clearly. Care is taken to monitor transport and storage situations, and to quantify any post-recovery adjustments affecting the ice and contained gases (e.g. Reference Bereiter, Schwander, Stocker and LuthiBereiter and others, 2009). I am a Senior Lecturer at Newcastle Univeristy, specialising in glaciology and glacial geology.
