Journal ArticleDOI

The middle Pleistocene transition: characteristics, mechanisms, and implications for long-term changes in atmospheric pCO2

TL;DR: In this paper, the emergence of low-frequency, high-amplitude, quasi-periodic (∼100-kyr) glacial variability during the middle Pleistocene in the absence of any significant change in orbital forcing indicates a fundamental change internal to the climate system.
Journal ArticleDOI

An updated radiocarbon-based ice margin chronology for the last deglaciation of the North American Ice Sheet Complex

April S. Dalton, +75 more
TL;DR: The most up-to-date and authoritative margin chronology for the entire ice sheet complex is featured in two publications (Geological Survey of Canada Open File 1574 [Dyke et al., 2003] and as mentioned in this paper ).
Journal ArticleDOI

Global neodymium hafnium isotope systematics — revisited

TL;DR: In this paper, the authors present new Nd and Hf isotope data on glacio-marine core-top sediments from around the perimeter of the Antarctic continent and use these calculations to test to what degree the seawater array could be a product of preferential weathering of non-zircon portions of the upper continental crust, implying retention of zircons in the solid residue of weathering.
Journal ArticleDOI

Glacial stratigraphy and paleomagnetism of late Cenozoic deposits of the north-central United States

TL;DR: The authors identified three groups of tills representing at least seven pre-Illinoian glaciations: two older groups of reverse-polarity tills containing low and intermediate proportions of crystalline clasts, respectively, and one younger group of normal porthole tills enriched in crystalline lithologies.
