Returning to the University of Leicester for the fifth year, the ECORD Summer School: Downhole Logging for IODP Science focuses on downhole logging within IODP and the applications of downhole measurements in various geoscientific fields, including paleoclimatology and sedimentology, as well as for broader geological and ecological processes. The Summer School is a 1-week long CPD-accredited course offering 36 hours of training in the core principles of petrophysics and downhole logging, from data collection to interpretation. The School will be hosted at the University of Leicester (UK) and will run from the 4th July to the 10th of July 2020. The course is open to applicants from the international community, but applications from early career researchers (including PhD students) are particularly encouraged. U.S.-affiliated students and researchers may also apply for travel support through the U.S. Science Support Program. A limited number of travel grants are available and priority may be given to applicants actively engaged or interested in research using IODP data. The deadline to apply for travel support and for the course has been extended to February 21, 2020.
