MitchellLoganCEOASConstraintsLateHoloceneSupplementaryMaterials.pdf

Creator:

Mitchell, Logan, Brook, Edward J., Lee, James E., Buizert, Christo, and Sowers, Todd

Abstract:

The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Radiometric ⁸¹Kr dating identifies 120,000-year-old ice at Taylor Glacier, Antarctica

Creator:

Buizert, Christo, Baggenstos, Daniel, Jiang, Wei, Purtschert, Roland, Petrenko, Vasilii V., Lu, Zheng-Tian, Mueller, Peter, Lee, James, Severinghaus, Jeffrey P., and Brook, Edward J.

Abstract:

We present the first successful ⁸¹Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four ~350 kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA). The ⁸¹Kr radiometric ages agree with independent...

Onset of deglacial warming in West Antarctica driven by local orbital forcing

Creator:

Fudge, T. J., Steig, Eric J., Markle, Bradley R., Schoenemann, Spruce W., Ding, Qinghua, Taylor, Kendrick C., McConnell, Joseph R., Brook, Edward J., Sowers, Todd, White, James W.

Abstract:

The cause of warming in the Southern Hemisphere during the most recent deglaciation remains a matter of debate[superscript 1,2]. Hypotheses for a Northern Hemisphere trigger, through oceanic redistributions of heat, are based in part on the abrupt onset of warming seen in East Antarctic ice cores and dated to 18,000...

C., Winstrup, Mai, Wong, Gifford J., and Woodruff, Thomas E.

Abstract:

The last glacial period exhibited abrupt Dansgaard–Oeschger climatic oscillations, evidence of which is preserved in a variety of Northern Hemisphere palaeoclimate archives¹. Ice cores show that Antarctica cooled during the warm phases of the Greenland Dansgaard–Oeschger cycle and vice versa[superscript 2,3], suggesting an interhemispheric redistribution of heat through a mechanism...
