Numerical experiments on firn isotope diffusion with the Community Firn Model
Autor: Vasileios Gkinis, Christian Holme, Emma C. Kahle, Max C. Stevens, Eric J. Steig, Bo M. Vinther
Publikováno v: Journal of Glaciology, Vol 67, Pp 450-472 (2021)
Advances in analytical methods have made it possible to obtain high-resolution water isotopic data from ice cores. Their spectral signature contains information on the diffusion process that attenuated the isotopic signal during the firn densificatio

Publikováno v: Annals of Glaciology, Vol 62, Pp 118-130 (2021)
An intermediate-depth (1751 m) ice core was drilled at the South Pole between 2014 and 2016 using the newly designed US Intermediate Depth Drill. The South Pole ice core is the highest-resolution interior East Antarctic ice core record that extends i

Continuous-Flow Analysis of δ17O, δ18O, and δD of H2O on an Ice Core from the South Pole
Autor: Eric J. Steig, Tyler R. Jones, Andrew J. Schauer, Emma C. Kahle, Valerie A. Morris, Bruce H. Vaughn, Lindsey Davidge, James W.C. White
Publikováno v: Frontiers in Earth Science, Vol 9 (2021)
The δD and δ18O values of water are key measurements in polar ice-core research, owing to their strong and well-understood relationship with local temperature. Deuterium excess, d, the deviation from the average linear relationship between δD and

Publikováno v: eISSN
The total air content (TAC) of polar ice cores has long been considered a potential proxy for past ice sheet elevation. Recent work, however, has shown that a variety of other factors also influence this parameter. In this paper we present a high-res

Antarctic paleotemperatures It has been widely thought that East Antarctica was ∼9°C cooler during the Last Glacial Maximum, close to the ∼10°C difference between then and now determined independently for West Antarctica. Buizert et al. used bo
