Abstract in brief

The study models how microplastic particles, influenced by biofouling such as algal growth, sink in the ocean and finds that smaller particles (around 0.1 mm) sink quickly and take longer to reach their initial sinking depth, with sinking timescales mainly dependent on particle size rather than density.
It reveals that in nutrient-poor areas like subtropical gyres, particles between 0.01 and 1 mm may not sink within 90 days, implying biological processes like algal growth might contribute to these plastics remaining afloat, complementing physical factors.
The research shows that larger particles (around 1 m) tend to sink due to vertical water movement (advection), especially in gyres, but in the equatorial Pacific, biofouling plays a bigger role, with minor seasonal variations such as increased sinking during spring algal blooms.]
