    Description: Oxygen isotope analyses of well-preserved foraminifera from Blake Nose (30°N paleolatitude, North Atlantic) and globally distributed deep-sea sites provide a long-term paleotemperature record for the late Albian-Maastrichtian interval that is difficult to reconcile with the existence of significant Cretaceous ice sheets. Given reasonable assumptions about the isotopic composition of Cretaceous seawater, our results suggest that middle bathyal water temperatures at Blake Nose increased from ~12°C in the late Albian through middle Cenomanian to a maximum of 20°C during the latest Cenomanian and earliest Turonian. Bottom waters were again ~12°C during the middle Campanian and cooled to a minimum of 9°C during the Maastrichtian. Correlative middle bathyal foraminifera from other ocean basins yield paleotemperature estimates that are very similar to those from Blake Nose. Comparison of global bottom-water temperatures and latitudinal thermal gradients suggests that global climate changed from a warm greenhouse state during the late Albian through late Cenomanian to a hot greenhouse phase during the latest Cenomanian through early Campanian, then to cool greenhouse conditions during the mid-Campanian through Maastrichtian.

    (Table T2) Stable carbon and oxygen isotopes of DSDP Leg 30, Leg 33, ODP Leg 130 and Leg 192 sites, Ontong Java Plateau (2004)
    PANGAEA
    Details
    Publication Date: 2024-01-09
    Description: Stable isotopic analyses of bulk carbonates recovered from Ontong Java Plateau during Ocean Drilling Program (ODP) Leg 192 (Holes 1183A and 1186A) show an ~0.5 per mil increase in d18O values from the upper Campanian/lower Maastrichtian to the upper Maastrichtian. This shift is consistent with widespread evidence for cooling at this time. Similar shifts were found at other localities on Ontong Java Plateau (Deep Sea Drilling Project [DSDP] Sites 288 and 289 and ODP Site 807) and at DSDP Site 317 on Manihiki Plateau. These data extend evidence for Maastrichtian cooling into the southwestern tropical and subtropical Pacific. The record of apparent cooling survives despite a significant diagenetic overprint at all sites. Comparing average Maastrichtian d18O values among sites suggests that diagenesis caused d18O to first be shifted toward higher values and then back toward lower values as burial depth increased. Carbon isotopes at the six sites show no apparent primary shifts, but at four sites, the Cretaceous/Tertiary boundary interval coincides with a negative excursion attributed to alteration of sediments near the boundary.

    (Table T1) Strontium isotope ratio and ages of ODP Hole 192-1183A and Hole 192-1186A sediments, Ontong Java Plateau (2004)

    Description: Strontium isotope stratigraphy of the Cretaceous sections recovered in Holes 1183A and 1186A generally matches trends expected from the seawater Sr isotope curve. Combined with biostratigraphic data, the 87Sr/86Sr measurements provide a good chronostratigraphic framework for these holes. In the mid-Cretaceous where the seawater Sr isotopic curve changes direction several times, biostratigraphy removes ambiguity in interpreting 87Sr/86Sr values. Furthermore, 87Sr/86Sr values refine the interpretation of several mid-Cretaceous unconformities suggested by nannofossil biostratigraphy. For the Campanian-Maastrichtian sediments in both holes, ages predicted from Sr isotope stratigraphy are as much as 2.5 m.y. younger than those from nannofossil stratigraphy. This offset likely results from differences in the way that ages are calibrated to nannofossil datums and the seawater Sr isotopic curve. Numerous Sr isotope values are high for their stratigraphic position, suggesting incorporation of excess 87Sr presumably derived from terrigenous clays. Other Sr isotope values suggest minor errors in the estimated ages of nannofossil datums.
