A high-accuracy Total Air Content setup: System performance and first results from Skytrain Ice Rise, Antarctica

Autor: Christoph Nehrbass-Ahles, Amy King, Helene Hoffmann, Mackenzie Grieman, Isobel Rowell, Jack Humby, Shaun Miller, Elizabeth Thomas, Thomas Bauska, Jochen Schmitt, Robert Mulvaney, Eric Wolff

Some modelling studies and sea level reconstructions suggest the loss of the West Antarctic Ice Sheet (WAIS) during the Last Interglacial (LIG) about ~120’000 ago, but direct evidence for a collapse of the WAIS is lacking. The WArm Climate Stabilit

The Little Ice Age CO2 drop: Natural, Anthropogenic or Artefact?

Autor: Amy King, Thomas Bauska, Ed Brook, Mike Kalk, Ivo Strawson, Jenna Epifanio, Helene Hoffman, Eric Wolff

We present new measurements of methane (CH4) and carbon dioxide (CO2) in the Skytrain ice core, with gas ages dated around 1610AD. The aim of these measurements is to improve our understanding of why there is a significant difference between measured

Climatic imprint in the mechanical properties of ice sheets and its effect on ice flow. Observations from South Pole and EPICA Dome C ice cores

Autor: Michelle Koutnik, Howard Conway, M. Reza Ershadi, Carlos Martín, Reinhard Drews, Thomas Bauska, Catherine Ritz

The climatic conditions over ice sheets at the time of snow deposition imprint distinctive crystallographic properties to the resulting ice. As it gets buried, its macroscopic structure evolves due to vertical compression and horizontal extension but

The ice core record of atmospheric CO2 variability during the Last Glacial Period: new insights from timing and isotopes

Autor: Thomas Bauska, Shaun Marcott, Ed Brook

Atmospheric carbon dioxide (CO2) concentrations during the last glacial period (70,000 – 23,000 years ago) fluctuated on millennial timescales closely following variations in Antarctic temperature. This close coupling has suggested that the sources

A paleoclimatic perspective of triple oxygen isotopes from gypsum in Holocene Thar Desert playa lakes

Autor: Alena Giesche, Yama Dixit, Fernando Gázquez, Thomas Bauska, Matthew Brady, Vikas K. Singh, Ravindra N. Singh, Cameron A. Petrie, David A. Hodell

The Thar Desert (NW India) has numerous evaporative saline playa lakes. Some are still active and others are dry and preserve up to several meters of sedimentary deposits. These deposits feature a variety of evaporite minerals, including the hydrated
