    Description: We extend existing high-resolution Oligocene–Miocene proxy records from Ocean Drilling Program (ODP) Leg 154. The extended record spans the time interval from ~17.86 to 26.5 Ma. The data are age calibrated against a new astronomical solution that affords a re-evaluation of the intricate interaction between orbital (“Milankovitch”) forcing of the climate and ocean system, and the fidelity with which this forcing is recorded in oxygen and carbon stable isotope measurements from benthic foraminifera, and associated lithological proxy records of magnetic susceptibility, colour reflectance, and the measured sand fraction. Our records show a very strong continual imprint of the Earth's obliquity cycle, modulate in amplitude every ~41 ka, a very strong eccentricity signal in the carbon isotope records, and a strong, but probably local, imprint of climatic precession on the coarse fraction and magnetic susceptibility records. Our data allowed us to evaluate how the interaction of long, multi-million year beats in the Earth's eccentricity and obliquity are implicated in the waxing and waning of ice-sheets, presumably on Antarctica. Our refined age model confirms the revised age of the Oligocene–Miocene boundary, previously established by analysis of the lithological data, and allows a strong correlation with the geomagnetic time scale by comparison with data from ODP Site 1090, Southern Ocean.

    Description: Magnetic susceptibility record of the individual core sections from Wilkens et al., (2017, DOI: 10.5194/cp-13-779-2017) along the adjusted composite splice from this study and singular spectrum analyses (SSA, Analyseries software, Paillard et al., 1996, DOI: 10.1029/96EO00259) of this magnetic susceptibility record along adjusted composite splice from this study, with the ages from previously published age model (Wilkens et al., 2017, DOI: 10.5194/cp-13-779-2017) and revised ages (age model described in this study). This is for the interval from 105.775 mcd (adjusted, this study) to 128.895 mcd (adjusted, this study), corresponding to the time interval from 3095 ka (adjusted, this study) to 3307 ka (adjusted, this study).

    Description: Total carbon measurement (LECO CS744 elemental analyser, Bremen University). The analyses were performed by heating 0.1 g of homogenised material in a ceramic dish and measuring the resulting CO2 in IR cells. The carbonate content has been calculated as the difference between the total carbon content and the organic carbon content, measured in a second sample that was pre-treated with hydrochloric acid to remove carbonates. Both measurements have an accuracy of 0.001 mg (1 ppm) or 0.5 % relative standard deviation (RSD). The inorganic carbon was then converted to carbonate content using the molecular mass of calcium carbonate. The carbonate content data were combined with dry bulk density (DBD) and sedimentation rate (SR, this study) to calculate the carbonate accumulation rate (CaCO3 AR) as CaCO3 AR = (CaCO3 % / 100) x DBD x SR for the four time intervals MIS 5, MIS 9, MIS KM5 and MCO for the Leg 154, Site 927, Ceara Rise, tropical Atlantic Ocean. The composite depths and age model presented are from this study.
