TL;DR: In this paper, a chrono-stratigraphy was developed on the high-sedimentation rate core MD94-103 (Indian Southern Ocean, 45°35′S 86°31′E, 3560 m water depth) by geomagnetic synchronization between the later core and NAPIS75, and 14C dates.

TL;DR: In this paper, the authors show that the observed changes can be explained by large-scale reorganization of intermediate water masses in the Atlantic and Indian Oceans over the last deglaciation, and they show that during Heinrich event 1 and the Younger Dryas, brine formation in the North Atlantic and Nordic Seas led to the production of intermediate waters that extended far enough in the South Atlantic to be deflected by the circumpolar currents into the Indian Ocean basin, creating a circulation branch at intermediate depths that was more active than today.

TL;DR: In this article, simple box model calculations are used to simulate the oceanic circulation during the last glacial maximum (LGM) and the main features of the δ13C and Δ14C distributions and of the lysocline depth may be explained by a circulation pattern very different from the modem one.

TL;DR: In this article, a new calibration data set based on 234 replicate analyses of 9 planktonic and 2 benthic species of foraminifera collected from recent core-top sediments, with calcification temperatures ranging from −2 to 25°C.

TL;DR: In this article, more than 1700 δ13C observations of the benthic foraminifera genus Cibicides from late Holocene sediments (δ13CCibnat) are compiled and compared with newly updated estimates of the natural (preindustrial) water column δ 13C of dissolved inorganic carbon (´13CDICnat) as part of the international Ocean Circulation and Carbon Cycling (OC3) project.
