| Description | Compilation and generation of new data confirms that tropical sea surface temperatures did decreased during the Eocene during a time of global cooling. Although SSTs changed by only a small amount, this indicates that a tropical thermostat (in the strictest sense) did not exist. Also modelling work that indicates that this decrease was due to CO2, rather than changing tectonics. |
| Exploitation Route | Developing collaborations with renewable energy sector: Our results highlight the important role of atmospheric carbon dioxide as a climate driver, emphasising the need to move to a carbon neutral economy. |

| Title | Data for: A long-term, high-latitude record of Eocene hydrological change in the Greenland region |
| Description | The following supplementary information includes additional figures (Figure S1-S3) and datasets. Dataset S1, which is uploaded separately, contains 8 tables: Table 1: Temperature and precipitation data obtained via HadCM3L Table 2: Plant-derived n-alkane distributions at ODP Site 913 during Eocene Table 3: Plant-derived di- and triterpenoids at ODP Site 913 during the Eocene Table 4: Hopanoid thermal maturity parameters at ODP Site 913 during the Eocene Table 5: GDGT distributions and temperature estimates at ODP Site 913 during the Eocene Table 6: Hydrogen isotopic composition of leaf wax biomarkers at ODP Site 913 during the Eocene Table 7: Apparent fractionations between leaf wax and source water compared between major taxanomic categories in modern plants Table 8: Estimates of modern-day precipitation d2Hprecip for locations on the Greenland coast. Estimates are derived from the Online Isotopes in Precipitation Calculator (Bowen, 2016) |
