Plastic litter is considered ubiquitous in the marine environment, having been found in all of the world's ocean basins, in the polar regions and at the Equator (van Sebille et al., 2015). Presently, there is a lack of knowledge regarding the transportation and distribution of this floating marine litter (van Sebille et al., 2020). Very few reliable and comparable data-sets exist on floating marine litter concentrations in the open ocean (Stanev & Ricker, 2019), and such studies are themselves very costly and prone to biases (Hardesty et al., 2017). As a result, numerical modeling has been used to advance our understanding of marine litter transport and accumulation patterns (e.g., Onink et al. (2019)).It has been shown using both observational data and particle tracking simulations that buoyant microplastics accumulate at the center of each subtropical ocean gyres in each of the five major ocean basins (Cózar et al., 2014;Eriksen et al., 2014;Law et al., 2014;van Sebille et al., 2015). The location of these accumulation zones, often termed 'ocean garbage patches', is attributed to the convergence of large scale open-ocean surface currents,
