Journal ArticleDOI
The middle Pleistocene transition: characteristics, mechanisms, and implications for long-term changes in atmospheric pCO2
Peter U. Clark,David Archer,David Pollard,Joel D. Blum,J. A. Rial,Victor Brovkin,Alan C. Mix,Nicklas G Pisias,Martin Roy +8 more
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

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
Tina van de Flierdt,Steven L. Goldstein,Sidney R. Hemming,Martin Roy,Martin Roy,Martin Frank,Alex N. Halliday +6 more
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
Evidence for iceberg armadas from East Antarctica in the Southern Ocean during the late Miocene and early Pliocene
Trevor Williams,Tina van de Flierdt,Tina van de Flierdt,Tina van de Flierdt,Sidney R. Hemming,Sidney R. Hemming,Elena Chung,Elena Chung,Martin Roy,Martin Roy,Steven L. Goldstein,Steven L. Goldstein +11 more
TL;DR: Sediments from Ocean Drilling Program Site 1165 in the Indian Ocean sector of the Southern Ocean (off Prydz Bay) contain a series of layers that are rich in ice-rafted debris (IRD) as mentioned in this paper.
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.
