    800 years of carbonate ion concentration and area-density of Globigerinoides ruber from the Cariaco Basin (2019)
    PANGAEA
    In:  Supplement to: Davis, Ashley N; Davis, Catherine V; Thunell, Robert C; Osborne, Emily B; Black, David E; Benitez-Nelson, Claudia R (2019): Reconstructing 800 Years of Carbonate Ion Concentration in the Cariaco Basin Using the Area Density of Planktonic Foraminifera Shells. Paleoceanography and Paleoclimatology, 34(12), 2129-2140, https://doi.org/10.1029/2019PA003698

    Description: Record of Cariaco Basin near-surface [CO₃²⁻] from 1240-2007 C.E. derived from the area-density (shell weight (μg)/shell area (μm²)) of the planktonic foraminifer Globigerinoides ruber (pink). Area-density is used as a proxy for [CO₃²⁻] following the relationship presented in Marshall et al. (2013), using the two cores PL07-71-BC and CAR25-1

    Neodymium isotopic record of planktonic foraminifera in sediment core MD81-LC21
    PANGAEA
    In:  Supplement to: Osborne, Anne H; Marino, Gianluca; Vance, Derek; Rohling, Eelco J (2010): Eastern Mediterranean surface water Nd during Eemian sapropel S5: monitoring northerly (mid-latitude) versus southerly (sub-tropical) freshwater contributions. Quaternary Science Reviews, 29(19-20), 2473-2483, https://doi.org/10.1016/j.quascirev.2010.05.015
    Details
    Publication Date: 2023-06-27
    Description: A well developed sapropel (S5) was deposited in the eastern Mediterranean during the Last Interglacial (Eemian), 124-119 ka. Freshwater contributions to the basin at this time can be traced using the isotopic composition of Nd in planktonic foraminifera. This enables differentiation between radiogenic sources to the south, under the influence of the African monsoon, and unradiogenic sources to the north, relating to the mid-latitude westerlies. Here we compare new Nd data, from a core in the southeast Aegean Sea, with published data from the Ionian and Levantine Seas. Shifts towards more radiogenic Nd in the lower and middle parts of sapropel S5 are most pronounced in the Ionian Sea record, with epsioln-Nd and d18O G. ruber co-varying more closely here than in the Levantine and Aegean Seas. This is consistent with a freshwater source proximal to the Ionian Sea site, likely indicating a substantial reactivation of rivers flowing northward from the central Saharan watershed. The lack, during S5 deposition, of a noticeable shift towards more unradiogenic Nd in the Aegean record would exclude a large influx of water from the northern borders of the eastern Mediterranean during sapropel deposition. These findings support a scenario whereby the Last Interglacial eastern Mediterranean was influenced strongly by the remote effects of an intensified African monsoon, with more local precipitation in the northern borders contributing relatively little to the sea surface composition.

    Publication Date: 2023-06-27
    Description: These data are in association with a study conducted in the Santa Barbara Basin, California, USA that were used to develop a 20th century record of ocean acidification in the California Current Ecosystem. These data are based on the planktonic foraminifera species G. bulloides' shell characteristics, specifically area-normalized shell weight (ANSW). Carbonate system calculations for the downcore record determined based on the proxy CO32- values using the CO2SYS program are also included in this archive.
