    Benthic foraminiferal assemblages and epifaunal isotope record of the Agulhas Plateau
    PANGAEA
    In:  Supplement to: Diz, Paula; Hall, Ian R; Zahn, Rainer; Molyneux, Elizabeth G (2007): Paleoceanography of the southern Agulhas Plateau during the last 150 ka: Inferences from benthic foraminiferal assemblages and multispecies epifaunal carbon isotopes. Paleoceanography, 22(4), PA4218, https://doi.org/10.1029/2007PA001511

    Description: Benthic foraminiferal assemblages and the carbon isotope composition of the epifaunal benthic foraminifera Epistominella exigua and Fontbotia wuellerstorfi have been investigated along core MD02-2589 located at the southern Agulhas Plateau (41°26.03'S, 25°15.30'E, 2660 m water depth). This study aims to evaluate changes in the benthic paleoenvironment and its influence on benthic d13C with a notable focus on E. exigua, a species associated with phytodetritus deposits and poorly studied in isotope paleoceanographic reconstructions. The benthic foraminiferal assemblages (〉63 µm) show large fluctuations in species composition suggesting significant changes in the pattern of ocean surface productivity conceivably related to migrations of the Subtropical Convergence (STC) and Subantarctic Front (SAF). Low to moderate seasonality and relatively higher food supply to the seafloor are indicated during glacial marine isotope stages (MIS) 6, 4, and 2 and during MIS 3, probably associated with the northward migration of the SAF and confluence with the more stationary STC above the southern flank of the Agulhas Plateau. The lowest organic carbon supply to the seafloor is indicated from late MIS 5b to MIS 4 as a consequence of increased influence of the Agulhas Front (AF) and/or weakening of the influence of the STC over the region. Episodic delivery of fresh organic matter, similar to modern conditions at the core location, is indicated during MIS 5c-MIS 5e and at Termination I. Comparison of this paleoenvironmental information with the paired d13C records of E. exigua and F. wuellerstorfi suggests that organic carbon offsets d13C of E. exigua from ambient bottom water d13CDIC, while its d13C amplitude, on glacial-interglacial timescales, does not seem affected by changes of organic carbon supply to the seafloor. This suggests that this species calcifies preferentially during the short time span of the year when productivity peaks and phytodetritus is delivered to the seafloor. Therefore E. exigua, while offset from d13CDIC, potentially more faithfully records the amplitude of ambient bottom water d13CDIC changes than F. wuellerstorfi, notably in settings such as the Southern Ocean that experienced substantial changes through time in the organic carbon supply to the seafloor.

    Description: Sortable silt mean grain sizes together with oxygen and carbon isotopic data produced on the benthic foraminiferal species Fontbotia wuellerstorfi are used to construct high-resolution records of near-bottom flow vigour and deep water ventilation at a core site MD02-2589 located at 2660 m water depth on the southern Agulhas Plateau. The results suggest that during glacial periods (marine oxygen isotope stages 2 and 6, MIS 2 and MIS 6, respectively), there was a persistent contribution of a well-ventilated water mass within the Atlantic to Indian oceanic gateway with a d13C signature similar to present-day Northern Component Water (NCW), e.g., North Atlantic Deep Water (NADW). The records of chemical ventilation and near-bottom flow vigor reflect changes in the advection of northern source waters and meridional variability in the location of the Antarctic Circumpolar Current and its associated fronts. We suggest that during Termination II (TII), changes in chemical ventilation are largely decoupled from near-bottom physical flow speeds. A mid-TII climate optimum is associated with a low-flow speed plateau concurrent with a period of increased ventilation shown in the benthic d13C of other Southern Ocean records but not in our benthic d13C of MD02-2589. The climate optimum is followed by a period of southern cooling around 128 ka coincident with a stronger influence of NCW to interglacial levels at around 124 ka. All proxy records show a near synchronous and rapid shift during the transition from MIS 5a-4 (73 ka). This large event is attributed to a rapid decrease in NADW influence and replacement over the Agulhas Plateau by southern source waters.

    Publication Date: 2023-07-10
    Description: Benthic foraminifera (〉125 µm fraction) were analysed in sediment samples from Hole U1381C (08°25.7027′N; 84°09.48′W, 2064.6 m water depth) located off Costa Rica (East Pacific) and obtained during IODP Expedition 344. We analysed samples each 10-20 cm in the uppermost 55 meters. The relative abundance of the most abundant species in the uppermost 47 meters representing the last 650 ka was discussed in Diz et al. (2018). Here we provide the full counts for the first 55 meters of the Hole U1381C.

    Bulk sedimentary nitrogen isotopes and nitrogen content of ODP Site 202-1242 (2021)
    PANGAEA
    Details
    Publication Date: 2023-07-10
    Description: The bulk sedimentary nitrogen isotopic measurements and relative contribution of nitrogen were analysed in ODP Site 202-1242 (7º51.352'N, 83º36.418'W, 1364 meters water depth) located off Costa Rica, in the East Equatorial Pacific. A selection of samples between 84 and 125 meters composite depth representing the interval between 720 and 1040 ka were dried (45ºC), ground and homogenised using a zircon ball mil. About 20 mg of sample were measured for their nitrogen isotopic composition by using an Elemental Analyzer FlashEA 1112 coupled to a ThemoFinningan MAT 253 Isotope Mass Spectrometer. The nitrogen content of the sample was measured using a micro-elemental analyser Fisons Carlo Erba EA1108.
