major economic and ecological impacts. Monitoring and modeling of anthropogenic litter
comes with large uncertainties due to the wide variety of litter characteristics, including size,
mass, and item type. It is unclear as to what the effect of sample set size is on the reliability
and representativeness of litter item statistics. Reliable item statistics are needed to (1)
