TL;DR: Analysis of deep-sea coral boron isotope data, as a proxy for pH and thus CO2 chemistry, provides evidence of CO2 storage in the deep Southern Ocean during the last ice age, and its rapid release on millennial to centennial timescales during deglaciation.

TL;DR: Radiocarbon data from uranium-thorium–dated deep-sea corals in the Equatorial Atlantic and Drake Passage over the past 25,000 years is reported, providing compelling evidence for a close coupling of ocean circulation and centennial climate events during the last deglaciation.

TL;DR: A consistent signal of the 231Pa/230Th proxy reveals a spatially coherent picture of western Atlantic circulation changes over the last deglaciation, which reveals a two-step AMOC slowdown at the beginning of the deglacial period.

TL;DR: Measurements of the 15N/14N of fossil-bound organic matter in the stony deep-sea coral Desmophyllum dianthus, a tool for reconstructing surface ocean nutrient conditions, provide the most spatially comprehensive evidence to date in support of the proposal that the entire Southern Ocean was nutrient-depleted during the last ice age relative to modern conditions.

TL;DR: The radiogenic strontium (Sr) and neodymium (Nd) isotope compositions of the detrital fraction of surface and subsurface sediments have been determined to trace sediment provenance and contributions from Asian dust off the east coast of Luzon Islands in the western Philippine Sea as discussed by the authors.
