Massive late Pleistocene detritus layers of the North Atlantic and their global climate imprint
[1] Millennial climate oscillations of the glacial interval are interrupted by extreme events, the so-called Heinrich events of the North Atlantic. Their near-global footprint is a testament toExpand
Climate change and the collapse of the Akkadian empire: Evidence from the deep sea
The Akkadian empire ruled Mesopotamia from the headwaters of the Tigris-Euphrates Rivers to the Persian Gulf during the late third millennium B.C. Archeological evidence has shown that this highlyExpand
Major middle Miocene global climate change: Evidence from East Antarctica and the Transantarctic Mountains
We present a glacial record from the western Olympus Range, East Antarctica, that documents a permanent shift in the thermal regime of local glaciers, from wet- to coldbased regimes, more than 13.94Expand
Mid-Miocene cooling and the extinction of tundra in continental Antarctica
The discovery of exceptionally well preserved fossils of lacustrine and terrestrial organisms from the McMurdo Dry Valleys sector of the Transantarctic Mountains are reported, providing novel constraints for the timing and amplitude of middle-Miocene cooling in Antarctica and revealing the ecological legacy of this global climate transition.

Initiation of the western branch of the East African Rift coeval with the eastern branch
Rifting of the eastern part of the East African Rift System was thought to have begun several million years before its western counterpart. Reconstructions of drainage development, combined withExpand
Long-lived Isotopic Tracers in Oceanography, Paleoceanography, and Ice-sheet Dynamics
This chapter focuses on the basis for using authigenic neodymium, lead, and hafnium isotopes in oceanography and paleoceanography. In particular, it reviews in detail the currently available data onExpand
Abrupt changes in Antarctic Intermediate Water circulation over the past 25,000 years
The formation and circulation of Antarctic Intermediate Water has varied over glacial–interglacial timescales. A neodymium record from the Atlantic Ocean basin suggests that changes in circulationExpand
Intensification and variability of ocean thermohaline circulation through the last deglaciation
Neodymium isotope ratios in the authigenic ferromanganese oxide component in a southeastern Atlantic core reveal a history of the global overturning circulation intensity through the lastExpand
Early Proterozoic crustal evolution: Geochemical and NdPb isotopic evidence from metasedimentary rocks, southwestern North America
Early Proterozoic ( 1X- 1.7 Ga) metasedimentary rocks in northern New Mexico and southern Colorado, USA, can be divided into turbidite successions (commonly volcanogenic) associated with mafic/Expand
