    Description: Orbital tuning and understanding climate response to astronomical forcing in the Miocene require detailed knowledge of the effect of tidal dissipation (Td) and dynamical ellipticity (dE) on astronomical solutions used to compute insolation and orbital target curves for paleoclimatic studies. These Earth parameters affect precession and obliquity; the determination of their effect is of fundamental importance, as phase relations between astronomical forcing and climate response can only be accurately calculated when the relative phasing between precession and obliquity is known. This determination can be achieved through comparison of solutions having different values for Td and/or dE with well‐understood paleoclimate data. In this paper we use quantitative color records of precession‐obliquity interference recorded in two successive 2.4 Myr eccentricity minima (9–9.6 and 11.5–12.1 Ma) in the Monte dei Corvi section in northern Italy to constrain the effect of Td, using the assumption of a direct response of sapropels to insolation. This quantitative approach results in a minimum uncertainty of astronomically tuned age models of ± 0.8 kyr and Td values 0.95 and 1.05 for the 9–9.6 Ma interval and of +4/−1 kyr (Td values between 0.95 and 1.15) for the 11.5–12.1 Ma interval. This (un)certainty not only limits the precision of determining phase relations but also improves our understanding of the limitations of tuned time scales and determining phase relations in the Miocene.

    Description: Marine sediment records from the Oligocene and Miocene reveal clear 400,000-year (400-kyr) climate cycles related to variations in orbital eccentricity. These cycles are also observed in the Plio-Pleistocene records of the global carbon cycle. However they are absent in the Late Pleistocene ice-age record over the past 1.5 million years. Here, we present a simulation of global ice volume over the past 5 million years with a coupled system of four 3-D ice-sheet models. Our simulation shows that the 400-kyr long eccentricity cycles of Antarctica vary coherently with d13C records during the Pleistocene suggesting that they drive the long-term carbon cycle changes throughout the past 35 million years. The 400-kyr response of Antarctica is eventually suppressed by the dominant 100-kyr glacial cycles of the large ice sheets in the Northern Hemisphere (NH).

    Late Pliocene benthic δ¹³C and δ¹⁸O from ODP Site 959 and δ13C from ODP Site 662 in the eastern equatorial Atlantic (2020)
    PANGAEA
    Details
    Publication Date: 2023-01-30
    Description: We present high-resolution late Pliocene (~2.7-3.5 Ma) benthic foraminiferal stable isotope records from eastern equatorial Atlantic ODP Site 959 (δ^13^C and δ^18^O) and ODP Site 662 (δ^13^C). The complementary δ^18^O record from Site 662 was published in Lisiecki and Raymo (2005; doi:10.1029/2004PA001071). Site 959 data was generated using the epibenthic species Cibicides wuellerstorfi and stable isotope analysis was performed at Utrecht University in 2016 on either a Thermo-Finnigan Kiel III automated preparation system coupled to a Thermo-Finnigan MAT 253 mass spectrometer, or a Thermo Finnigan GasBench-II carbonate preparation device coupled to a Thermo Finnigan Delta-V mass spectrometer. Site 662 data was generated using Cibicides wuellerstorfi when possible, and alternatively, a combination of Cibicides species (Cibicides spp.) was used. Stable isotope analysis was performed in the early 1990s at Massachusetts Institute of Technology using a VG Prism mass spectrometer. These new records are combined with previously published benthic δ¹³C and δ¹⁸O records. By assuming that both δ¹³C and δ¹⁸O behave as conservative tracers, we estimate the isotopic end-members of deep Atlantic water masses. At least three endmembers are needed to explain the spatial δ¹³C-δ¹⁸O variability in the deep North Atlantic Ocean: two Northern Component Water (NCW) and one Southern Component Water (SCW) water masses. We use a ternary mixing model to quantify the mixing proportions between SCW and NCW in the deep Atlantic ocean.

    Mediterranean Outflow Water variability during the Early Pleistocene (2017)

    Description: Gaining insights into the evolution of Mediterranean Outflow Water (MOW) during the Early Pleistocene climate transition has been so far hampered by the lack of available paleoclimatic archives. Here we present the first benthic foraminifera stable oxygen and carbon isotope records and grain-size data from IODP Expedition 339 Site U1389 presently located within the upper core of the MOW in the Gulf of Cadiz for the time interval between 2.6 and 1.8 Ma. A comparison with an intermediate water mass record from the Mediterranean Sea strongly suggest an active MOW supplying Site U1389 on glacial-interglacial timescales during the Early Pleistocene. We also find indication that the increasing presence of MOW in the Gulf of Cadiz during the investigated time interval aligns with the progressive northward protrusion of Mediterranean sourced intermediate water masses into the North Atlantic, possibly modulating the intensification of the North Atlantic Meridional Overturning Circulation at the same time. Additionally, our results suggest that MOW flow strength was already governed by precession and semi-precession cyclicity during the Early Pleistocene against the background of glacial-interglacial variability dominated by the obliquity cycle of Earth's inclination axis.

    Glacial Mediterranean Outflow recoinstruction at IODP Site 339-U1390 (2018)

    Description: The state of Atlantic Meridional Overturning Circulation (AMOC) is influenced by both the strength and the location of the Mediterranean Outflow (MOW) plume in the Gulf of Cadiz. To evaluate the influence of MOW on AMOC over deglaciations, precise and accurate salinity and temperature reconstructions are needed. For this purpose, we measured Mg/Ca and clumped isotopes of several benthic foraminiferal species at IODP Site U1390 in the Gulf of Cadiz. The clumped isotope results of Cibicidoides pachyderma, Uvigerina mediterranea and Pyrgo spp. are consistent between species and record no significant difference in Glacial to Holocene DWT. Over the deglaciation, the Mg/Ca-based temperatures derived from U. mediterranea indicate three periods of MOW absence at site U1390. Mg/Ca-based temperatures of Hoeglundina elegans and C. pachyderma are on average 6 °C too cold when compared to the present core-top temperature, which we explain by a carbonate ion effect on these epibenthic species related to the high alkalinity of the MOW. Combining DWT estimates with the benthic oxygen isotope data and considering different relationships between seawater oxygen isotopes and salinity, we infer a salinity decrease of MOWby 3 to 8 units over the deglaciation, and 4 units during S1, accounting for the global d18O depletion due to the decrease in ice volume. Our findings confirm that the Mediterranean Sea accumulates excess salt during a glacial low stand, and suggest that this salt surged into the Atlantic over the deglaciation, presumably during HS1.
