      Key Points

      • Late glacial oceanography and preservation of planktic foraminifera—Fram Strait
      • Dissolution of CaCO3 coincided with periods of Arctic water influence
      • Glacial CaCO3—preservation better than during the Holocene
    2. Radiocarbon dating of planktonic foraminifer shells: A cautionary tale (pages 13–29)

      Key Points

      • Foraminifer radiocarbon age versus G. menardii fragmentation index
      • Age of foraminifers offset by 3500 years; age increases with dissolution
      • Fragments generally older than whole shells
    3. Simulated changes in atmospheric dust in response to a Heinrich stadial (pages 30–43)

      Lisa N. Murphy, Amy C. Clement, Samuel Albani, Natalie M. Mahowald, Peter Swart and Monica M. Arienzo

      Key Points

      • A shift in the AEJ reduces dust deposition over the North Atlantic during HS
      • Wind changes have the largest effect on dust emission and deposition
    4. Vertical oxygen minimum zone oscillations since 20 ka in Santa Barbara Basin: A benthic foraminiferal community perspective (pages 44–57)

      Sarah E. Moffitt, Tessa M. Hill, Kenichi Ohkushi, James P. Kennett and Richard J. Behl

      Key Points

      • Bølling/Allerød OMZ shoaled to <300m of contemporaneous sea level
      • High sensitivity of OMZ vertical shoaling in response to global warming events
      • Strong interaction between margin OMZ and hypoxia within restricted basin
    5. Atlantic-Pacific seesaw and its role in outgassing CO2 during Heinrich events (pages 58–70)

      L. Menviel, M. H. England, K. J. Meissner, A. Mouchet and J. Yu

      Key Points

      • Ocean is a carbon sink when the AMOC shuts down
      • Ocean is a carbon source if AABW and NPDW strengthen during an AMOC shutdown
      • Enhanced AABW and NPDW lead to a pCO2 increase during Heinrich stadials 1 and 4
