At the end of 2017, I spent two months on a scientific expedition into the Southern Ocean to look at Cretaceous climate and tectonics with the International Ocean Discovery Program and ECORD. It was an incredible experience with many stories still to tell. Here I produced a video with filming and editing work by Cristiane Delfina for BBC Future about what life is like onboard a world at sea. Watch the video at the link below. You can check out where the boat is now and what scientific secrets it is uncovering here.
