    Description: The deep ocean has long been recognized as the reservoir that stores the carbon dioxide (CO2) removed from the atmosphere during Pleistocene glacial periods. The removal of glacial atmospheric CO2 into the ocean is likely modulated by an increase in the degree of utilization of macronutrients at the sea surface and enhanced storage of respired CO2 in the deep ocean, known as enhanced efficiency of the biological pump. Enhanced biological pump efficiency during glacial periods is most easily documented in the deep ocean using proxies for oxygen concentrations, which are directly linked to respiratory CO2 levels. We document the enhanced storage of respired CO2 during the Last Glacial Maximum (LGM) in the Pacific Southern Ocean and deepest Equatorial Pacific using records of deglacial authigenic manganese, which form as relict peaks during increases in bottom water oxygen (BWO) concentration. These peaks are found at depths and regions where other oxygenation histories have been ambiguous, due to diagenetic alteration of authigenic uranium, another proxy for BWO. Our results require that the entirety of the abyssal Pacific below approximately 1,000 m was enriched in respired CO2 and depleted in oxygen during the LGM. The presence of authigenic Mn enrichment in the deep Equatorial Pacific for each of the last five deglaciations suggests that the storage of respired CO2 in the deep ocean is a ubiquitous feature of late-Pleistocene ice ages.
    Description: This work was performed with support from the National Science Foundation (NSF) over about 30 years. The TT013 and NBP9802 cores were collected during the U.S. JGOFS program. Their collection and analyses were supported by NSF OCE-9022301 and OPP-95303398 to R. F. Anderson, and NSF OCE 9301097 to R. W. Murray. Coring and radiocarbon analyses on NBP1702 were funded by NSF OPP-1542962. XRF analysis on NBP9802 and NBP1702 cores, as well as additional radiocarbon measurements, was funded by an LDEO Climate Center Grant to F. J. Pavia.

    Description: A series of catastrophic iceberg discharges termed Heinrich events punctuated the last ice age in the North Atlantic. During Heinrich events, coarse terrigenous debris released from the drifting icebergs and preserved in deep-sea sediments serves as an indicator of their passage. Quantifying the vertical flux of ice-rafted debris (IRD) in pelagic sediments can resolve questions regarding the timing and variation in ice sheet calving intensity. In this study, 230Thxs-based IRD flux was measured throughout the last glacial period in a deep-sea sediment core from the western North Atlantic (EW9303-37JPC, 43.68°N, 46.28°W, 3981 m), and complemented during Marine Isotope Stages (MIS) 1-3 by measurements from DY081-GVY01 (50.16°N, 45.51°W, 3721m) in the Labrador Sea. The cores are downstream from the Hudson Strait, a leading candidate for the conduit of the icebergs from the Laurentide ice sheet (LIS). We compare our results with the directly equivalent existing data in the eastern North Atlantic, and show that EW37JPC and DY001GVY have higher IRD fluxes during all Heinrich events, notably including 3 and 6. This study demonstrates that the Laurentide played a role in all Heinrich events and raises the likelihood that a single mechanism can account for their genesis.
