The European Petrophysics Consortium (EPC) is heavily involved in this expedition, as part of the ECORD (European Consortium for Ocean Research Drilling) Science Operator (ESO). Johanna Lofi (University of Montpellier), Erwan Le Ber and Laurence Phillpot (University of Leicester) will coordinate all of the downhole and core petrophysical measurements. Data collected downhole provide a continuous record of rock properties along the borehole. A multi-sensor core logger (MSCL) is used to measure physical properties of recovered cores, at a resolution of 2 cm. By comparing downhole and core logging the exact depth of the cores in the borehole can be calculated; a very important aspect of this expedition, as key horizons such as the PETM and the K-Pg boundary should be sampled. Finally, the combination of downhole and core petrophysical measurements will be crucial to test current hypotheses of peak ring formation. This expedition represents an exceptional opportunity to investigate a truly exciting geological feature: this unique peak ring, testimony of one of Earth’s most dramatic events.

After the offshore phase of the expedition, core samples will be sent to the IODP Bremen Core Repository in Germany, where further analyses will be done this autumn. EPC will continue to coordinate the acquisition of more petrohysical data on the core material recovered.
