The samples for objective 1 were collected during the Exp. 396 sampling party to Bremen and during fieldwork in Svalbard August 2023. The data for this objective were collected during the secondment visits to University of Utrecht and by sending off samples prepared at the University of Oslo for stable isotope analysis. Some of the findings were presented at EGU 2023 (Vickers et al., 2023, EGU23-5465). The publications arising are in prep. The data for Objective 2 were collected during the secondment trips to both University of Utrecht and ETH Zürich. The data and initial interpretations were presented at EGU 2022. One paper dealing with clumped isotope methodology has been published in GCA (Looser et al., 2022) and the main paper arising from this work is in prep. The scope of objective 3 was expanded to cover glendonites from all geological time. The database has been made yet remains to be entirely published (2 arising publications still in review or in prep.), but parts of the database have been published in Counts et al. (accepted, JSR); Vickers et al., (2024, CoP); Schultz et al. (2023, NJG), and Vickers et al. (2022, GCA). A further two papers are in review (Jelby et al. (GSL Spec. Pub.) or in prep (Vickers et al., Cret. Res.). Further data was presented at several international conferences, including Goldschmidt 2023 and CBEP 2022.
Objective 4 set out to develop a model to explain the evidence for cooling during the early Paleogene prevailing greenhouse – hothouse climate, building on the findings from the pervious objectives. Various potential hypotheses to explain the evidence for cooling are presented in Vickers et al. (2024 CoP), and a paper presenting evidence to support one particular hypothesis is in prep.
