    Isotope and Mg/Ca results from ODP Site 184-1145 (2005)
    PANGAEA
    In:  Supplement to: Oppo, Delia W; Sun, Youbin (2005): Amplitude and timing of sea-surface temperature change in the northern South China Sea: Dynamic link to the East Asian monsoon. Geology, 33(10), 785-788, https://doi.org/10.1130/G21867.1

    Publication Date: 2024-01-09
    Description: Magnesium/calcium (Mg/Ca) ratios of foraminiferal shells from a sediment core from the northern South China Sea, a semi-enclosed basin in the western tropical Pacific, document variations in sea-surface temperature (SST) during the past 145 k.y. Glacial SSTs were 4°C colder than interglacial SSTs. During the last deglaciation, most of the warming was accomplished in a single abrupt step after continental ice-sheet decay had already begun, but warming and ice-sheet demise were nearly synchronous during the penultimate deglaciation. Abrupt SST changes of the past 15 k.y. were apparently synchronous with events in East Asian monsoon rainfall, suggesting that variations in monsoon winds and their influence on surface circulation of the western Pacific exerted a strong control on northern South China Sea SSTs. We suggest that this link persisted for the previous 130 k.y., during which time orbital-scale 2-3°C SST changes and several small (〈/=2°C) abrupt SST events occurred in the northern South China Sea. The similar timing of northern South China Sea SST, on a benthic d18O time scale, to a well-dated speleothem record from eastern China suggests that the demise of ice sheets associated with the penultimate deglaciation did not precede Northern Hemisphere summer insolation increase. Our results suggest that surface waters had higher d18O values during times of strong summer monsoon than during times of weak monsoon, likely reflecting a redistribution of 18O-depleted rainfall from land during times of strong summer monsoons, to the western Pacific during times of weaker summer monsoons.

    In:  Supplement to: Marchitto, Thomas M; Oppo, Delia W; Curry, William B (2002): Paired benthic foraminiferal Cd/Ca and Zn/Ca evidence for a greatly increased presence of Southern Ocean Water in the glacial North Atlantic. Paleoceanography, 17(3), 10-1-10-18, https://doi.org/10.1029/2000PA000598

    Description: Benthic foraminiferal d13C and Cd/Ca studies suggest that deep Atlantic circulation during the Last Glacial Maximum was very different from today, with high-nutrient (low d13C, high Cd) deep Southern Ocean Water (SOW) penetrating far into the North Atlantic. However, if some glacial d13C values are biased by productivity artifacts and/or air-sea exchange processes, then the existing d13C data may be consistent with the continual dominance of North Atlantic Deep Water (NADW). Cibicidoides wuellerstorfi Cd/Ca results presented here indicate that the glacial North Atlantic was strongly enriched in dissolved Cd below ~2500 m depth. If NADW formation was still vigorous relative to SOW formation, these data could be explained by either increased preformed nutrient levels in the high-latitude North Atlantic or by increased organic matter remineralization within lower NADW. High glacial Zn/Ca values in the same samples, however, are best explained by a substantially increased mixing with Zn-rich SOW. The cause was most likely a partial replacement of NADW by less dense Glacial North Atlantic Intermediate Water. This reorganization also lowered deep North Atlantic [CO3]2- concentrations by perhaps 10 to 15 µmol/kg.

    In:  Supplement to: Came, Rosemarie E; Oppo, Delia W; McManus, Jerry F (2007): Amplitude and timing of temperature and salinity variability in the subpolar North Atlantic over the past 10 k.y. Geology, 35(4), 315-318, https://doi.org/10.1130/G23455A.1
    Details
    Publication Date: 2024-03-02
    Description: Paired planktic foraminiferal d18O and Mg/Ca data reveal trends of increasing temperatures (~3 °C) and salinities in the subpolar North Atlantic over the course of the Holocene, which were punctuated by abrupt events. The trends likely reflect an insolation-forced northward retreat of the boundary between polar and North Atlantic subsurface waters. The superimposed variability does not appear to be periodic, but tends to recur within a broad millennial band. The records provide convincing evidence of open-ocean cooling (nearly 2°C) and freshening during the 8.2 ka event, and suggest similar conditions at 9.3 ka. However, the two largest temperature oscillations in our record (~2°C) occurred during the past 4 k.y., suggesting a recent increase in temperature variability relative to the mid-Holocene, perhaps in response to neoglaciation, which began at about this time.
