Steph, who is normally based at the University of Exeter, talked about the research she’s been doing en route. She’s asking two main questions: 1) where on our route will we find the most plastic and plankton occurring together; 2) can we find ‘real world’ evidence (as opposed to lab-based evidence, which already exists) that plankton ingest plastic? The critical question is the second one, and the method is brilliant.
