Evolution of the Global Overturning Circulation since the Last Glacial Maximum based on marine authigenic neodymium isotopes
Abstract The Global Overturning Circulation is linked to climate change on glacial-
interglacial and multi-millennial timescales. The understanding of past climate-circulation …

[HTML][HTML] Atmospheric CO2 during the Mid-Piacenzian Warm Period and the M2 glaciation
The Piacenzian stage of the Pliocene (2.6 to 3.6 Ma) is the most recent past interval of
sustained global warmth with mean global temperatures markedly higher (by~ 2–3 C) than …

North Atlantic deep water during Pleistocene interglacials and glacials
The global ocean overturning circulation is a major means of distributing heat around the
Earth, and an important trigger or amplifier of climate change. This study presents a 1.5-Myr …

North Atlantic deep water production during the Last Glacial Maximum
Abstract Changes in deep ocean ventilation are commonly invoked as the primary cause of
lower glacial atmospheric CO2. The water mass structure of the glacial deep Atlantic Ocean …

Antarctic icebergs reorganize ocean circulation during Pleistocene glacials
The dominant feature of large-scale mass transfer in the modern ocean is the Atlantic
meridional overturning circulation (AMOC). The geometry and vigour of this circulation …

The large-scale evolution of neodymium isotopic composition in the global modern and Holocene ocean revealed from seawater and archive data
Abstract Neodymium isotopic compositions (143 Nd/144 Nd or ε Nd) have been used as a
tracer of water masses and lithogenic inputs to the ocean. To further evaluate the …

Evidence for a Northern Hemispheric trigger of the 100,000-y glacial cyclicity
The causes of the Mid-Pleistocene Transition, the shift from∼ 41-ky to 100-ky interglacial–
glacial cycles and more intense ice ages, remain intensely debated, as this fundamental …

Mode transitions in Northern Hemisphere glaciation: co-evolution of millennial and orbital variability in Quaternary climate
DA Hodell, JET Channell - Climate of the Past, 2016 - cp.copernicus.org
We present a 3.2 Myr record of stable isotopes and physical properties at IODP Site U1308
(reoccupation of DSDP Site 609) located within the ice-rafted detritus (IRD) belt of the North …

Global and regional temperature change over the past 4.5 million years
Much of our understanding of Cenozoic climate is based on the record of δ18O measured in
benthic foraminifera. However, this measurement reflects a combined signal of global …
