The Corinth Rift, Greece, has been forming over the last 5 million years and is a rare example of continental rifting in its initial stages of development. The main active rift today (1.5-2.5 million years old) has a closed drainage system, high sedimentation rates and high extension rates making it an ideal natural laboratory to examine early rift development and how the landscape responds to tectonic and climate forcing factors. Furthermore, with high strain rates across the rift and with high sedimentation rates, it may be possible to gain an insight into the rifting process with unprecedented resolution in both space (1-10’s kms) and time (20-50 thousands of years). Thus from October 2017, a team of scientists, drillers and staff from the European Consortium for Ocean Research Drilling Science Operator  (ECORD-ESO) will take part in International Ocean Drilling Programme (IODP)  Expedition 381, to drill the offshore Corinth Rift. As a member of the science party for this exciting expedition, and a proponent of the original proposal to IODP, I will present an introduction to the project, detailing the various results of the virtual site survey that was used to identify the achievable targets for coring as well as elaborating on the major goals of the expedition.

Casey has a BSc With Honors from the University of Edinburgh and a PhD from the University of Southampton from 2013. After this he worked as a Post Doctoral Research Fellow at the University of Southampton working on the Virtual Site Survey for drilling the offshore Corinth Rift. This survey was the basis for the IODP expedition, which is now about to be conducted, and was performed together with a group of scientists who submitted the proposal to the IODP. From 2015, Casey has been working as a VISTA Scholar at GEO.
