[ Update this Record ]

Summary
Abstract: The data are 3He exposure ages from lateral moraine bands on Mount Waesche, a
volcanic nunatak in Marie Byrd Land, West Antarctica. The proximal part of the
moraine is up to 45 meters above the present ice level was deposited
approximately 10,000 years ago, well after the glacial maximum in the Ross
Embayment. The upper distal part of the moraine may record multiple earlier
ice advances. The data are all generated by crushing and melting mineral
separates (mostly olivine) in vacuo, and measurements with a noble gas mass
spectrometer at Woods Hole Oceanographic Institution. Full details can be
found in Ackert et al. (Science, 1999, vol. 286, p.276-280).
