The fate and transport pathways of floating debris are still not completely understood. The material with densities exceeding that of seawater is expected to sink to deeper water layers and eventually reach the seafloor. However, the fate of the plastic waste with lower density is complicated to determine, amongst others, due to complex weathering processes including biofilm formation on its surface. However, several studies have identified accumulation areas at the sea surface. The so-called “Great Pacific Garbage Patch” in the North Pacific Subtropical Gyre is probably the most recognized one among these areas, which likely continues to accumulate plastic rapidly.
