Fig 6 - The rise and fall of the Cretaceous Hot Greenhouse climate

Fig. 6. Compiled Cretaceous oxygen and carbon isotope data for benthic and planktonic foraminifera from Sites 257 and 258 in the southern Indian Ocean and Sites 327, 511, 689 and 690 in the southern South Atlantic (this study) shown relative to (left to right): (1) proxy estimates for Cretaceous pCO 2 including the following: blue squares with crosses: Frenelopolis conifer estimates with ± 1σ around the mean pCO 2 level (Barral et al., 2017); green triangles: liverwort δ 13 C, red circles: pedogenic carbonate δ 13 C, and crosses: leaf stomata shown with LOESS best fit line through all but conifer data (from Foster et al., 2017 compilation); (2); (3) Sr isotope seawater curve (McArthur et al., 2012); (4) regional and global Oceanic Anoxic Events (Takashima et al., 2006); (5) global large igneous province (LIP) magma flux estimated by Coffin et al. (2006); and (6) global mid-ocean ridge magma flux estimated by Müller et al. (2016). Global subduction zone length estimated by van der Meer et al. (2014). Strongly negative δ 18 O and δ 13 C values across the Aptian-Albian boundary interval are considered an artifact of a more restricted and shallower depositional basin compared to later periods (see text).
