Magnitude of isotope/temperature scaling for interpretation of central Antarctic ice cores

A New Technique for Dielectric Logging of Antarctic Ice Cores

Interpretation of recent Antarctic sea ice variability

[1] Trends in the satellite-derived Antarctic sea ice concentrations (1979–2002) show pronounced increase (decrease) in the central Pacific sector (Bellingshausen/ western Weddell sector) by 4–10% per decade. Confidence levels for these regional trends exceed 95%. Positive polarities of the Antarctic Oscillation (AAO) lead to more (less) ice in the eastern Ross/Amundsen sector (Bellingshausen/n...

Advanced microstructural characterization of four East Antarctic firn/ice cores

The microstructures and microchemistry of four US International Trans-Antarctic Scientific Expedition ice cores were examined, at three depths (30, 60, 90m) each, using scanning electron microscopy, including electron backscattered patterns and energy-dispersive spectroscopy (EDS), in order to assess the relationship between chemical and physical properties. The physical characteristics (grain ...

Antarctic temperatures over the past two centuries from ice cores

[1] We present a reconstruction of Antarctic mean surface temperatures over the past two centuries based on water stable isotope records from high-resolution, precisely dated ice cores. Both instrumental and reconstructed temperatures indicate large interannual to decadal scale variability, with the dominant pattern being anti-phase anomalies between the main Antarctic continent and the Antarct...
