Changes in deep-ocean carbon storage during the last glacial cycle were closely linked to variations in deep-water oxygenation, which reflects the combined influences of ocean ventilation and export production. Yet the relative importance of these processes remains difficult to disentangle. Whilst the …

Today, the Southern Ocean (SO) is the primary sink of anthropogenic heat and carbon, yet anthropogenic warming and ozone depletion have altered its circulation and stratification, creating uncertainty about the persistence of this sink. Evidence from the last glacial period and deglaciation …

Abstract. Understanding the evolution of deep ocean circulation and chemistry over the last glacial cycle is key for elucidating the ocean’s role in modulating atmospheric CO2 changes on millennial and orbital timescales. Marine Isotope Stage (MIS) 4 is a key paleoclimatic interval …

Antarctic ice core evidence indicates that atmospheric CO2 levels increased during Heinrich Stadial (HS) 1 and the Younger Dryas (YD) during the last deglaciation. A substantial fraction of this carbon is believed to have stemmed from the ocean interior, released, in part, …

During Heinrich Stadial 1 (HS1), δ13C decreased throughout most of the upper North Atlantic between∼ 1000 – 2500 m, and in some deeper South Atlantic sites. Most studies explain the δ13C decrease as a response to a weakening of the Atlantic circulation, …

Luminescence emitted by minerals has long been used in paleoenvironmental studies, particularly thermoluminescence (TL) from carbonates. TL emission in calcite is controlled by the type and quantity of defects in the crystal lattice, which may act as charge traps and/or recombination centers. …

Abstract. Changes in the marine reservoir age (MRA) of the surface ocean are important information used for radiocarbon dating of marine sediment cores or archaeological artifacts. MRA changes are expressed relative to the atmosphere, and as such are dependent on the prevailing …
