Abrupt changes in climate have occurred in many locations around the globe over the last
glacial cycle, with pronounced temperature swings on timescales of decades or less in the …

Abstract The Weddell Gyre (WG) is one of the main oceanographic features of the Southern
Ocean south of the Antarctic Circumpolar Current which plays an influential role in global …

Abstract Extreme, abrupt Northern Hemisphere climate oscillations during the last glacial
cycle (140,000 years ago to present) were modulated by changes in ocean circulation and …

The most recent ice age was characterized by rapid and hemispherically asynchronous
climate oscillations, whose origin remains unresolved. Variations in oceanic meridional heat …

Abstract Antarctic Bottom Water (AABW), which fills the global ocean abyss, is derived from
dense water that forms in several distinct Antarctic shelf regions. Previous modeling studies …

Geochemical redox proxies indicate that seafloor anoxia occurred during the latest
Ordovician glacial maximum, coincident with the second pulse of the Late Ordovician mass …

The neodymium (Nd) isotopic composition of seawater is commonly used as a proxy to study
past changes in the thermohaline circulation. The modern database for such reconstructions …

Antarctic ice-core data reveal that the atmosphere experienced abrupt centennial increases
in CO2 concentration during the last deglaciation (~ 18 thousand to 11 thousand years ago) …

Over the past three million years, Earth's climate oscillated between warmer interglacials
with reduced terrestrial ice volume and cooler glacials with expanded polar ice sheets …

Radiocarbon is an extremely useful carbon cycle tracer and radiometric dating tool. Here,
we review the main principles and challenges involved in the use of radiocarbon in …
