The Ocean Training Partnership is an international alliance of marine science organisations that coordinates research vessel-based experiential teaching and learning. It is an initiative led by Partnership for Observation of the Global Ocean (POGO) in collaboration with the Strategic Marine Alliance for Research and Training (SMART) and the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI). The project is funded by the Nippon Foundation and hosted by Marinetraining.eu. The Partnership aims to develop a collaborative, sustainable approach to train competent marine science graduates and equip them with the technical skills and practical experience necessary to work across multiple oceanographic disciplines in challenging environments.
