Description
Summary:Earth's climate during the Maastrichtian (latest Cretaceous) was punctuated by brief warming and cooling episodes, accompanied by perturbations of the global carbon cycle. Superimposed on a long-term cooling trend, the middle Maastrichtian is characterized by deep-sea warming and relatively high values of stable carbon-isotope ratios, followed by strong climatic variability towards the end of the Cretaceous. A lack of knowledge on the timing of climatic change inhibits our understanding of underlying causal mechanisms. We present an integrated stratigraphy from Integrated Ocean Drilling Program (IODP) Site U1403, providing an expanded deep ocean record from the North Atlantic (Expedition 342, Newfoundland Margin). Distinct sedimentary cyclicity suggests that orbital forcing played a major role in depositional processes, which is confirmed by statistical analyses of high resolution elemental data obtained by X-ray fluorescence (XRF) core scanning. Astronomical calibration reveals that the investigated ... : Supplement to: Batenburg, Sietske J; Friedrich, Oliver; Moriya, Kazuyoshi; Voigt, Silke; Cournède, Cécile; Moebius, Iris; Blum, Peter; Bornemann, André; Fiebig, Jens; Hasegawa, Takashi; Hull, Pincelli M; Norris, Richard D; Röhl, Ursula; Sexton, Philip F; Westerhold, Thomas; Wilson, Paul A; IODP Expedition 342 Scientists (2017): Late Maastrichtian carbon isotope stratigraphy and cyclostratigraphy of the Newfoundland Margin (Site U1403, IODP Leg 342).
