AB The accelerated discard and mismanagement of human-made products are resulting in the continued input oflitter into the oceans. Models and field observations show how floating litter can accumulate in remote areasthroughout the global ocean, but far less is known about the non-floating litter fraction. Seagrass meadows playan important role in the sediment and natural-debris dynamics, and likely also in the storage and processing ofnon-floating litter. In this work, non-floating litter was studied across six Posidonia oceanica meadows. Litteraccumulated mainly around the landside edge of the meadow. The outer margin of the edge predominantlytrapped macro-litter, whilst microplastics accumulated mainly along the inner margin. On average, macro-litterconcentrations increased 3-fold after heavy rainfall. Retention of non-floating litter by coastal meadows facilitates the recurrent landward-seaward conveyance of the easily-transportable litter (mainly plastic items) and itsfragmentation before it is buried or transferred to deeper areas.
