... cores. Here we present a record of sea surface temperature change across the Paleocene-Eocene boundary for a nearshore, shallow marine section located on the eastern margin of North America. The SST record, as inferred from TEX 86 data, indicates a minimum of 8 °C of warming, with peak temperatures...

Figure 2. Global correlation of TEX86 (tetraether index of 86 carbon atoms) values with temperature (T) in Holocene surface sediments for T > 0 °C (dashed line A; after Schouten et al., 2002) and correlation of TEX86 values with temperature in selected Holocene surface sediments for T > 20 °C (solid line B). Gray band indicates range of TEX86 values in most middle Cretaceous sedimentary rocks.

Carbon-isotope stratigraphy (Dickson et al., 2017), TEX86 data, calculated sea-surface temperatures (SSTs), and depth intervals (A–D; described in text) from Ocean Drilling Program Site 1138, Core 69R. SSTs calculated using the following empirical calibrations: TEX-linear (O’Brien et al., 2017); TEX86H (Kim et al., 2010); and the deep-time version of BAYSPAR (Tierney and Tingley, 2015).
