Seafloor Explorer - Online Seminar Series

Dedicated to bring together UK/EU-based scientists working on ocean tectonic settings, across disciplines including but not limited to geology, geophysics, geochemistry, marine geosciences. Seminars are hosted virtually at 3pm UK time on Tuesdays mid-month (once a month). To suggest speakers please email us directly.
