That is the question that Prof. Alan Deidun, resident academic within the Department of Geosciences of the Faculty of Science, along with a cohort of high-profile co-authors, posed within a study recently published in the Microplastics and Nanoplastics journal. Specifically, the study overviews a plethora of marine litter monitoring survey data available for different regions of the world ocean, as well as modeling data, in order to answer this compelling question.
